There are 4 storage class specifiers in C - auto, extern, static, and register - that determine where a variable is stored in memory and the scope and lifetime of the variable. Auto variables are stored in CPU memory and last within the function, extern variables can be defined anywhere but last till the end of the program, static variables retain their value between function calls and are stored in CPU memory, and register variables are stored in register memory and also last within the function but access the fastest.

Storage classess of C progamming 
There are four storage classes in C programming that determine how long a variable exists: 1) automatic variables exist within the function they are declared in and do not retain their value between calls, 2) external variables can be accessed from any function but must be declared in only one file, 3) static variables retain their value between function calls, and 4) register variables attempt to be stored in processor registers for faster access but may be stored in memory instead if registers are full.
Storage Class Specifiers in C++
The document discusses storage classes in C++. It explains that every variable has a storage class and scope. The storage class determines where storage is allocated and how long it exists, while scope specifies visibility. It describes the auto, register, static, and extern storage classes. Auto variables are allocated and destroyed on block entry/exit, register suggests register storage, static retains value between function calls, and extern extends scope to other files. It provides examples of each storage class and their differences between C and C++.
Storage Classes and Functions
The document discusses storage classes and functions in C/C++. It explains the four storage classes - automatic, external, static, and register - and what keyword is used for each. It provides examples of how to declare variables of each storage class. The document also discusses different types of functions like library functions, user-defined functions, function declaration, definition, categories based on arguments and return values, actual and formal arguments, default arguments, and recursion.
Storage classes
Storage classes in C determine the scope, lifetime, and visibility of variables. The four main storage classes are auto, extern, static, and register. Auto variables are local to a block or function and allocated on the stack. Extern variables are defined elsewhere but declared in the current file, making them global. Static variables retain their value between function calls and are allocated statically. Register variables attempt to store in CPU registers for faster access but may be allocated on the stack if no registers are available.
Storage Class in C Progrmming
The document discusses the different storage classes in C programming language: auto, extern, static, and register. Auto variables are local variables that are destroyed when the block ends. Extern variables have global scope and lifetime until the end of the program. Static variables retain their value between function calls and have lifetime throughout the program. Register variables behave like auto but are stored in CPU registers for faster access.
Storage class in c
Storage classes in C determine where variables are stored in memory and their scope. The main storage classes are automatic, static, external, and register. Automatic variables are declared within a function and exist only during its execution. Static variables retain their value between function calls. External variables have global scope and exist throughout program execution. Register variables are stored in processor registers for faster access but only a limited number can be register variables.

Storage classes in c language
The document discusses storage classes in C programming which determine where a variable is stored in memory and the scope and lifetime of a variable. There are four main storage classes - automatic, external, static and register. Automatic variables are local to a block and vanish after the block ends. External variables can be accessed from other files. Static variables retain their value between function calls and last the lifetime of the program. Register variables are stored in CPU registers for faster access but there are limited registers.
Notes of Important Programming Fundamental Questions
A function is a named block of code that performs a specific task. The function header contains the return type, name, and parameters. The function body contains the code that is executed when the function is called. Functions make code reusable and easier to maintain. Variables declared inside a function are local and can only be accessed within the function. Variables declared outside functions are global and can be accessed throughout the program. Arrays store multiple values of the same type and allow accessing elements via an index. One-dimensional arrays use a single index while two-dimensional arrays use two indexes.
11 lec 11 storage class
The document discusses storage classes in C which determine where a variable is stored in memory and how long it exists. There are four main storage classes: automatic, register, static, and external. Automatic is the default and variables exist for the duration of the block they are declared in. Register variables store in CPU registers but cannot be used with scanf. Static variables retain their value between function calls while existing in the block. External variables are global and visible throughout a program.
C language 2
Loops allow blocks of code to be repeatedly executed. The three types of loops in C are while loops, for loops, and do-while loops. While loops check the condition before each iteration. For loops allow initialization, condition checking, and increment/decrement in the loop header. Do-while loops check the condition after executing the block at least once. Break and continue statements can be used to exit or skip portions of loops. Switch statements compare a value to multiple case values and execute the corresponding block.
FUNCTION CPU
This document discusses functions in C programming. It defines functions as a group of statements that perform a specific task and have a name. Main functions must be included in every C program as it is where program execution begins. Functions help facilitate modular programming by dividing programs into smaller parts. Functions can be user-defined or built-in library functions. Parameters can be passed to functions by value or by reference. Functions can call themselves through recursion. Variables have different storage classes like auto, register, static, and external that determine scope and lifetime.
Storage class in C Language
The storage class determines where a variable is stored in memory (CPU registers or RAM) and its scope and lifetime. There are four storage classes in C: automatic, register, static, and external. Automatic variables are stored in memory, have block scope, and are reinitialized each time the block is entered. Register variables try to store in CPU registers for faster access but may be stored in memory. Static variables are also stored in memory but retain their value between function calls. External variables have global scope and lifetime across the entire program.
Storage classes in c++
The document discusses different storage classes in C++ including automatic, external, static, register, and mutable. It provides the syntax and examples of each:
- Automatic variables are declared with auto and have function block scope and lifetime.
- External variables use extern and have whole program global visibility.
- Static variables are declared with static and have whole program lifetime but local visibility.
- Register variables are intended for fast access and declared with register but storage is implementation-defined.
- Mutable variables allow changing class member values in const member functions and are declared with mutable.
C language
C is a widely used programming language that is easy to learn and can create efficient programs. It allows working with low-level activities and can be compiled on many platforms. A C program consists of preprocessor commands, functions, variables, statements, expressions, and comments. A basic "Hello World" program is presented that prints the message using a printf statement.

Storage classes
The document discusses different types of storage classes in C programming:
1) Auto variables are allocated on the stack and have block scope, being destroyed when the block exits. Register variables are a type of auto variable stored in CPU registers for faster access.
2) External variables are declared outside functions and remain in memory for the program duration.
3) Static variables retain their value between function calls, stored in static storage duration. They are initialized only once.
Function in C++
A function provides a convenient way of packaging a computational recipe, so that it can be used as often as required. A function definition consists of two parts: interface and body. The interface of a function (also called its prototype) specifies how it may be used. It consists of three entities:
The function name. This is simply a unique identifier.
The function parameters (also called its signature). This is a set of zero or more typed identifiers used for passing values to and from the function.
The function return type. This specifies the type of value the function returns. A function which returns nothing should have the return type void.
The body of a function contains the computational steps (statements) that comprise the function.
storage class
The document discusses the different storage classes in C - automatic, register, static, and external. Each storage class determines where a variable is stored (memory or registers), its initial value, scope, and lifetime. The automatic class is the default, and variables have local scope and are reinitialized each time a block is entered. The register class stores variables in CPU registers for faster access but variables behave like automatic. The static class retains variable values between function calls, and external makes variables global and accessible throughout a program.
FRP
This document provides an overview of Functional Reactive Programming (FRP). It defines common FRP terminology like Observables, EventStreams, Behaviours, and Signals. It also describes the Observer interface used in FRP. The document compares two popular FRP libraries, RxJS and Bacon.js, and highlights their key features. It briefly mentions some other FRP-related libraries and languages. Finally, it provides links to resources for learning more about FRP through libraries, courses, videos, and papers.
Linq & lambda overview C#.net
Lambda expressions allow functions to be used as variables or fields through special syntax using the => operator, which separates the function parameters and body. The document provides examples of lambda expressions with different parameter types and bodies. It also explains that the => operator separates the left side (parameters) from the right side (body) and is not a comparison operator in this context. LINQ (Language Integrated Query) introduces extension methods that allow querying collections like lists and arrays, even those not yet in memory. An example uses the Average extension method to calculate the average of all elements in an integer array.

Pointers C programming
A pointer is a variable that stores the memory address of another variable. Pointers allow functions to modify variables in the caller and are useful for handling arrays and dynamic memory allocation. Pointers contain the address of the memory location they point to. Pointer variables can be declared to hold these memory addresses and can then be used to indirectly access the value at the addressed location.

C language for Semester Exams for Engineers
This document provides an overview of programming languages and their classification. It discusses machine language, assembly language, and high-level languages. Machine language is directly understood by computers as binary code. Assembly language uses mnemonics instead of binary and requires an assembler. High-level languages like C use familiar syntax and require compilers or interpreters to convert code to machine language. C was created in 1972 and features portability, structured programming, and supports various data types. The document also covers C language elements like variables, constants, keywords, operators, and input/output functions.
Arrays 1D and 2D , and multi dimensional
The document discusses arrays in C programming language. It defines arrays as fixed-sized sequenced collections of elements of the same data type that share a common name. One-dimensional arrays represent lists, while two-dimensional arrays represent tables with rows and columns. Arrays must be declared before use with the size specified. Elements can be accessed using indices and initialized. Common operations like input, output, sorting and searching of array elements are demonstrated through examples.
Handling of character strings C programming
This document discusses handling of character strings in C programming. It covers declaring and initializing string variables as character arrays, reading strings from the terminal using scanf() and gets(), writing strings to the screen using printf() and puts(), performing arithmetic operations and comparisons on characters, concatenating strings, and commonly used string handling functions like strcpy(), strcat(), and strcmp().
Difference between structure and union
Structure and union differ in how they allocate memory and access members. Structure allocates memory for all members and allows accessing all members at any time, while union allocates space for the largest member and only allows accessing one member at a time. Both use struct and union keywords respectively to declare them, with struct defining elements and union defining a single element that shares the same memory space.
Function C programming
The document discusses C functions, including their definition, types, uses, and implementation. It notes that C functions allow large programs to be broken down into smaller, reusable blocks of code. There are two types of functions - library functions and user-defined functions. Functions are declared with a return type, name, and parameters. They are defined with a body of code between curly braces. Functions can be called within a program and allow code to be executed modularly and reused. Parameters can be passed by value or by reference. Functions can return values or not, and may or may not accept parameters. Overall, functions are a fundamental building block of C that improve code organization, reusability, and maintenance.
C programming for Computing Techniques

Advance Microcontroller AVR
- Microcontrollers are small computers contained on a single chip that contain a processor core, memory, and input/output interfaces. They are used in automatically controlled embedded systems.
- The AVR is a family of microcontrollers developed by Atmel in the 1990s. It uses RISC architecture and is commonly used in hobbyist and commercial projects due to its low cost and availability.
- Code is burned onto AVR microcontrollers using a software program called Atmel Studio, which allows writing code in C or assembly language. The program is then loaded onto the microcontroller through its pins.
Planers machine
The document describes a planer machine, which is used to generate flat surfaces and cut slots. It moves the entire workpiece beneath the cutting head on a reciprocating table. The main parts of a planer include the bed, table, column, cross rail, and tool head. The bed supports the machine and table, which holds the workpiece. The column and cross rail guide the reciprocating motion of the table and movement of the tool head, which can have multiple cutting tools. Planer operations include planing horizontal and vertical surfaces as well as slots. Safety precautions must be followed when using the heavy machinery.
Programming ATmega microcontroller using Embedded C
Embedded C is a subset of C used for microcontrollers. It uses header files specific to microcontrollers and removes input/output functions like scanf and printf since sensors provide input and ports provide output. Control structures like if/else statements and loops remain the same. Programs configure ports as inputs or outputs using Data Direction and Port registers and read/write values to Port registers to set pin values. An example blinks an LED connected to port B by setting the port high, waiting, and setting it low in a loop.
AVR Fundamentals
1. Calibrate the line sensor readings by taking multiple samples while turning left and right to determine the minimum and maximum values.
2. Continuously read the line sensor position and calculate the proportional, integral, and derivative terms based on the error from the center.
3. Determine the difference in motor powers needed to turn toward the center based on the PID values, without allowing negative powers.
4. Set the motor speeds based on the power difference to steer toward the center line.

Key aspects of Embedded C include data types, storage classes, arithmetic and logical operations, relational operations, and conditional branching instructions like if-else statements to direct program flow.
Conventional machining vs. non conventional machining
Conventional machining involves physically removing material from a workpiece using a harder cutting tool, typically through mechanical forces. Non-conventional machining utilizes other forms of energy like thermal, chemical, or electrical instead of mechanical forces and may not require physical contact or chip formation. While conventional machining can be used for most materials economically, non-conventional machining allows for higher precision machining of hard metals and complex parts but requires more advanced equipment and skilled operators.

Terms and Definitions.pdf
A flowchart is a pictorial representation of a program algorithm, which is the step-by-step process to execute a program. The pre-processor directive processes source code before compilation. Variables store data values like numbers and characters. C language was developed by Dennis Ritchie in 1972. Functions can be user-defined or library functions. Storage classes determine lifetime, visibility, location, and initial values of variables, including automatic, static, register, and external.
Storage classes in c language
Storage Classes in C
Storage Classes are used to describe the features of a variable/function. These features basically include the scope, visibility and life-time which help us to trace the existence of a particular variable during the runtime of a program.
Storage classes
The document discusses different storage classes in C programming language. There are several storage classes that determine where a variable is stored in memory and how long it remains in memory. The main storage classes covered are auto, static, register, and extern.
Auto variables are local variables declared within a function and stored on the stack frame. They are initialized with garbage values and exist only for the duration of the function call. Static variables are similar to auto but remain in memory for the duration of the program. Register variables hint to store in CPU registers for fast access but the compiler may ignore. Extern variables are defined in one file and declared in others to share the variable across files.

C language updated
The document provides an introduction to the C programming language. It discusses that C is a general-purpose, procedural language widely used for system and application programming. The document then covers C language basics like data types, variables, constants, operators, functions, decision making structures and more with examples. It aims to help a beginner get started with learning the C language.
Storage class
Storage class defines the scope and lifetime of a variable. The main storage classes are automatic, register, static, and external. Automatic variables are allocated on the stack and have block scope, while register variables are stored in CPU registers for faster access but cannot have their address taken. Static variables retain their value between function calls and have either file or block scope. External variables are declared outside of functions and visible throughout the entire program.
01 Variables
The document discusses C variables including data types, naming rules, scope, lifetime, type modifiers, type sizes and ranges, storage specifiers, type qualifiers, and new C99 types. Key points include that variables hold data in memory, common C data types are void, char, int, float, and double, and variables can have local, global, or formal parameter scope depending on where they are declared.
Code generation errors and recovery
The document discusses code generation in compilers. It describes the code generator as taking an intermediate representation as input and producing target code. Key issues addressed include memory management, instruction selection and scheduling, and register allocation. The document also covers common compiler errors like lexical, syntactic, semantic and logical errors. It discusses different error recovery strategies used by parsers like panic mode, statement mode, and use of error productions.

1) Comments, preprocessor directives, header files, the main function, identifiers, special symbols, and punctuation that are elements of programming languages.
2) Explanations and examples of each concept like how comments annotate source code, preprocessor directives process special instructions, and header files contain function declarations.
3) The goal for students to be able to identify and understand these fundamental programming concepts after completing this chapter.
Compiler Design Material
The phases of a compiler are:
1. Lexical analysis breaks the source code into tokens
2. Syntax analysis checks the token order and builds a parse tree
3. Semantic analysis checks for type errors and builds symbol tables
4. Code generation converts the parse tree into target code
Storage classes
This document discusses different storage classes in C programming: automatic, external, static, and register. It explains where variables of each class are stored (memory vs registers), their default initial values, scopes (local vs global), and lifetimes (duration of existence). Automatic variables are local to a block/function, external variables are global, static variables can be local or global depending on declaration, and register variables are stored in CPU registers for faster access.

Computer systems consist of hardware and software. System software manages hardware components and includes device drivers, operating systems, servers, and utilities. Programming software provides tools to assist programmers. Application software aids tasks through business, design, databases, and other programs. There are low-level languages close to machine code like machine language and assembly language and high-level languages like C that are closer to English. Creating and running a C program involves writing code, compiling it, linking, loading, and executing the program.
Dineshmaterial1 091225091539-phpapp02
The document discusses the different phases of a compiler and storage allocation strategies. It describes:
1. The phases of a compiler include lexical analysis, syntax analysis, semantic analysis, intermediate code generation, code optimization, and code generation.
2. Storage allocation strategies for activation records include static allocation, stack allocation, and heap allocation. Languages like FORTRAN use static allocation while Algol uses stack allocation.
3. Parameter passing mechanisms include call-by-value, call-by-reference, copy-restore, and call-by-name. Call-by-value passes the actual parameter values while call-by-reference passes their locations.

It provides an example C program to calculate the area of a circle and explains each section of the code. Finally, it covers various C programming concepts like header files, character set, tokens, constants, variables and data types.
C programming session10
1. Embedded C requires compilers to create executable files that can be downloaded and run on microcontrollers, while C compilers typically generate code for operating systems on desktop computers.
2. Embedded systems often have real-time constraints and limited memory and other resources that require more optimization, unlike most desktop applications.
3. Programming for embedded systems focuses on optimally using limited resources and satisfying timing requirements using basic C constructs and function libraries.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

Types of storage class specifiers in c programming
- 1. Types of Storage Class Specifiers in C: There are 4 storage class specifiers available in C language. They are, 1. auto 2. extern 3. static 4. register S.No. Storage Specifier Storage place Initial / default value Scope Life 1 auto CPU Memory Garbage value local Within the function only. 2 extern CPU memory Zero Global Till the end of the main program. Variable definition might be anywhere in the C program 3 static CPU memory Zero local Retains the value of the variable between different function calls. 4 register Register memory Garbage value local Within the function Note: For faster access of a variable, it is better to go for register specifiers rather than auto specifiers. Because, register variables are stored in register memory whereas auto variables are stored in main CPU memory. Only few variables can be stored in register memory. So, we can use variables as register that are used very often in a C program.
