Difference between structured and object oriented programming
Advantages of object oriented programming
C++ is an object-oriented programming language that is a superset of C and was created by Bjarne Stroustrup at Bell Labs in the early 1980s. C++ supports features like classes, inheritance, and object-oriented design while also being compatible with C. Some key characteristics of C++ include its support for object-oriented programming, portability, modular programming, and C compatibility. C++ programs are made up of tokens like identifiers, keywords, literals, punctuators, and operators.
This document discusses variables in C programming. It explains that variables are names that refer to memory locations where values can be stored and changed during program execution. It provides the syntax for declaring variables using different data types like int, float, double, and char. Rules for variable names are also outlined, such as starting with a letter or underscore and avoiding reserved words.
Constants are values that do not change during program execution and include numeric constants like integers and floating point numbers, as well as string or character constants. Variables are identifiers that are used to refer to values that can change during program execution. Common variable types in C include integers, floating point numbers, characters, and strings. Variables must be declared with a data type before being assigned values and have naming conventions like starting with a letter and being less than 32 characters.
This document discusses pushdown automata (PDA) and how they can be used to accept context-free languages. It defines a PDA as a 7-tuple that includes a finite set of states, input symbols, stack symbols, initial state, initial stack symbol, set of final states, and a transition function. A context-free grammar is also defined as a 4-tuple that includes variables, terminals, production rules, and a start symbol. The document then shows how to construct a PDA that is equivalent to a given context-free grammar by defining transition rules based on the grammar productions. An example of converting a grammar to a PDA using this construction method is also provided.

Data file handling in python binary & csv fileskeeeerty
This document discusses binary files and CSV (comma separated value) files in Python. It covers creating and reading binary files using the pickle module's dump() and load() methods. It also covers various binary file operations like inserting/appending, searching, updating and deleting records. For CSV files, it describes the characteristics and advantages/disadvantages of CSV format. It provides examples of writing to and reading from CSV files in Python using the csv module.
The document provides an overview of compilers by discussing:
1. Compilers translate source code into executable target code by going through several phases including lexical analysis, syntax analysis, semantic analysis, code optimization, and code generation.
2. An interpreter directly executes source code statement by statement while a compiler produces target code as translation. Compiled code generally runs faster than interpreted code.
3. The phases of a compiler include a front end that analyzes the source code and produces intermediate code, and a back end that optimizes and generates the target code.

C was developed in the early 1970s by Dennis Ritchie at Bell Labs. It was created based on earlier languages like ALGOL and BCPL and was strongly integrated with the UNIX operating system. In 1983, the ANSI committee standardized C, creating ANSI C, and in 1990 the ISO standardized C, creating ANSI/ISO C. C is an important systems programming language due to its efficiency, portability, and ability to interface with assembly language. A basic C program structure includes header files, a main function, and statements between curly braces.
Looping Statements and Control Statements in PythonPriyankaC44
This document discusses looping statements and control statements in Python. It explains while loops, for loops, and the use of break, continue, else and pass statements. Some key points:
- While loops repeatedly execute statements as long as a condition is true. For loops iterate over a sequence.
- Break and continue statements can alter loop flow - break exits the entire loop, continue skips to the next iteration.
- The else block in loops runs when the condition becomes false (while) or the sequence is complete (for).
- Pass is a null operation used when syntax requires a statement but no operation is needed.
Several examples of loops and control statements are provided to demonstrate their usage.
The document discusses the benefits and advantages of the Python programming language. Python is described as a high-level, easy to use language that can be used for general programming as well as mobile and web development. It has many advantages, such as being easy to learn and use, having a large standard library, and being cross-platform. Some disadvantages are that it requires more memory than languages like C/C++ and has limited database access.
This document provides a history of the C programming language. It discusses how C evolved from earlier languages like BCPL and B that were used for operating systems and were typeless. It then describes key events like Dennis Ritchie creating C at Bell Labs in 1972 and the influential book The C Programming Language by Kernighan & Ritchie in 1978 that helped popularize C. The document also gives brief overviews of influential earlier languages like ALGOL and BCPL that influenced the creation of C.
Functions allow programmers to organize code into reusable blocks. A function is defined using the def keyword and can accept parameters. The body of a function contains a set of statements that run when the function is called. Functions can return values and allow code to be reused, reducing errors and improving readability. Parameters allow information to be passed into functions, while return values allow functions to provide results.

C is a general purpose, high-level programming language that was developed in the 1970s. It is widely used to create operating systems and is the precursor to many popular languages today. C code is compiled into machine-readable code that can be run on different computer systems. C has features like control structures, looping statements, arrays, and macros that make it well-suited for both business and scientific applications. It is commonly used to write operating systems like UNIX, Windows, Mac OS, and Linux.
This document provides an introduction to the Python programming language. It discusses that Python is a popular general-purpose programming language created by Guido van Rossum in 1980. It outlines that Python is used for web development, artificial intelligence, software development, and more. It also discusses setting up the programming environment, using functions, variables, arithmetic operations, user input, comments, conditions, and loops in Python programs. Major companies that use Python are also mentioned.
There are two main types of language processing activities: program generation and program execution. Program generation aims to automatically generate a program in a target language from a source program through a program generator. Program execution can occur through either translation, which translates a source program into an equivalent target program, or interpretation, where an interpreter reads and executes the source program statement-by-statement.
this presentation will walk you through basic introduction to python, major features of python, how python runs on our system and some important commands used in python.
C is a general-purpose programming language developed in the early 1970s. It produces very fast executable code and is widely used for operating systems, language compilers, utilities and other system software. The document provides an overview of the history and development of C, why it is still useful today, basic C programming concepts like tokens, constants, variables and data types, and the overall structure and execution of a C program.
The document discusses the structure and process of a compiler. It has two major phases - the front-end and back-end. The front-end performs analysis of the source code by recognizing legal/illegal programs, understanding semantics, and producing an intermediate representation. The back-end translates the intermediate representation into target code. The general structure includes lexical analysis, syntax analysis, semantic analysis, code generation and optimization phases.
The document discusses Turing machines. It begins by introducing Alan Turing as the father of the Turing machine model. A Turing machine is a general model of a CPU that can manipulate data through a finite set of states and symbols. It consists of a tape divided into cells that can be read from and written to by a tape head. The tape head moves left and right across the cells. The document then provides examples of constructing Turing machines to accept specific languages, such as the language "aba" and checking for palindromes of even length strings. Transition tables are used to represent the state transitions of the Turing machines.
Programming involves encoding algorithms into programming languages so that computers can execute them. An algorithm is needed first to solve a problem before a program can exist. Programming languages provide control constructs like sequential processing, selection, and iteration to represent algorithmic steps. They also provide data types to represent both the process and data used in algorithms.
This document discusses how text is stored on computers. It explains that each character is assigned a unique binary code value known as ASCII (American Standard Code for Information Interchange). ASCII used 7-bit codes to represent 128 common English characters, while Extended ASCII expanded to 8 bits to include additional characters. It also describes control characters as non-printable ASCII codes that perform functions like backspace. Finally, it defines a character set as the full repertoire of symbols a computer system can represent for a given language.
This document discusses character sets like ASCII and Unicode. ASCII maps English letters, numbers, and symbols to 7-bit binary codes and was the original standard, while Unicode is now more widely used as it supports over 110,000 characters from writing systems around the world, including ASCII as a subset for compatibility. An example at the end shows converting decimal values into ASCII text using an ASCII conversion table.

This document discusses character encoding systems used to represent textual data in computing. It describes several character encoding standards including ASCII, EBCDIC, ISO 646, ISO 885, and UTF-16. ASCII is a 7-bit encoding that can represent 128 characters and was limited as it does not support languages with large character sets. EBCDIC is an 8-bit encoding mainly used on IBM mainframe computers. UTF-16 is a 16-bit Unicode encoding that can represent over 65,000 characters and supports representation of text in many languages.
The document discusses Unicode and file handling topics for an ABAP workshop. It covers characters and encoding, ASCII standards, glyphs and fonts, extended ASCII issues, character sets and code pages, little and big endian formats, Unicode, Unicode transformation formats, Unicode in SAP systems, file interfaces, and error handling for files on application and presentation servers. Unicode provides a unique number for every character to standardize representation across languages, platforms, and programs.
The document discusses different character sets used in computing. It describes the ASCII character set which uses 128 characters and numbers to represent English letters, numbers and symbols. It also discusses the extended character set which includes 255 characters like symbols and international letters. Finally, it introduces Unicode which began in 1989 and aims to support encoding for all languages and alphabets in the world using up to 65,000 characters, grouping related symbols into scripts to serve multiple languages.
ASCII (American Standard Code for Information Interchange) is a 7-bit character encoding scheme where each character is assigned a number from 0-127. It was developed in 1963 to provide a standard for coding characters like letters, numbers, and symbols. Computers use ASCII to represent text characters numerically so they can be stored and processed using binary numbers.
ASCII is an industry standard 7-bit code developed in 1963 that assigns binary values to letters, numbers, and other characters to represent text and control characters in computing devices. Most computers use the ASCII standard to represent text, allowing data to be transferred between computers. ASCII codes provide a mapping between binary data and human-readable characters so that text can be visually represented on screens and in printouts.
This is a very old presentation but if you gloss over the usage of VB6 there is plenty of value. I presented this to the VBUG Annual Conference in 2003.
The document discusses Java character sets, tokens, keywords, identifiers, literals, and data types. It provides details on:
1. Java uses the Unicode character set which supports characters from many languages.
2. The smallest individual units in a Java program are called tokens, which include keywords, identifiers, literals, punctuators, and operators.
3. Keywords are reserved words with special meanings, identifiers name variables and other items, and literals are fixed data values like integers and strings.

This document summarizes encodings in computing, including ASCII, ISO-8859, Unicode, and how they are handled in Ruby 1.8 and 1.9. It discusses that text encoding and content are separate concepts and recommends using UTF-8. It also explains Ruby 1.8's limited Unicode support and how Ruby 1.9 introduced multilingualization to allow setting source encoding and handling different encoded strings.
Unicode is a character encoding standard that aims to support all languages of the world. It evolved from limitations of earlier standards like ASCII that could only represent English characters. Unicode uses 16-bit or 32-bit encodings to represent over 1 million characters, as opposed to ASCII's 128 characters. Popular Unicode encodings include UTF-8, UTF-16, and UTF-32. The widespread adoption of Unicode has allowed globalization of text and the internet by supporting the simultaneous use of different languages.
This document discusses different encoding schemes and number systems used in computers. It begins by explaining how keyboard characters are mapped to binary codes that computers can understand. This is done through encoding schemes like ASCII and UNICODE which assign unique codes to characters. It then describes different number systems like decimal, binary, octal and hexadecimal that are used to represent numbers in a format understood by computers and humans. Decimal uses base-10, binary uses base-2, octal uses base-8 and hexadecimal uses base-16.
Computers represent both numeric and non-numeric characters using predefined codes. The ASCII code represents 128 characters using 7 bits, while ASCII-8 extends this to 256 characters using 8 bits. ISCII was developed for Indian languages and allows simultaneous use of English and Indian scripts using 8 bits per character. Unicode is now the universal standard adopted by all platforms that assigns a unique number to every character worldwide for interchange, processing and display of written texts across languages.
Text is represented in computers using character encoding schemes like ASCII and Unicode that assign a unique binary number to each character. When a key is pressed on a keyboard, the character is converted to its binary number using the encoding scheme so it can be processed and displayed by the computer. ASCII encodes the most common English characters using 7-bit binary numbers, but is limited to 128 characters total. Unicode was created to support encoding characters for more languages using 16-bit or 32-bit binary representations.
C is a programming language created by Dennis Ritchie at Bell Labs in 1972 to develop the UNIX operating system. It quickly became popular due to its efficiency, flexibility, and portability. In 1989, ANSI standardized C to promote consistency, and it has since become one of the most widely used programming languages. Variables in C must be declared before use and can be numeric like integers and floats, or character strings. Variable names follow specific rules and types must be specified in declarations.
Java Course 7: Text processing, Charsets & EncodingsAnton Keks
Lecture 7 from the IAG0040 Java course in TTÜ.
See the accompanying source code written during the lectures: https://github.com/angryziber/java-course
Do you know the difference between charset & encoding? Every programmer nowadays MUST understand these terms, how they work, and how to use them. Otherwise we constantly face broken software refusing to work with international characters properly.
The document discusses various topics related to the C programming language including low-level languages, data types, operators, expressions, and control flow statements. It begins by explaining machine language, assembly language, and high-level languages. It then covers basic data types in C like integer, floating-point, character, and string constants. Various categories of operators used in C expressions are defined along with examples. Control flow statements like if-else, while, for, break and continue are also introduced.
The document discusses compilers and their role in translating high-level programming languages into machine-readable code. It provides examples of Fortran code being compiled into Java byte code. A compiler consists of a front end that analyzes syntax and semantics and a back end that generates machine code. The front end performs lexical analysis, parsing, and generates an abstract syntax tree and symbol table. The back end then takes this intermediate representation and converts it into executable machine instructions.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...indexPub
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.

5. WHAT IS A CHARACTER SET?
A character set is the set of valid characters that a language
can recognize. It can be a letter, a digit , a symbol or some
control characters such as backspace, tab or newline.
• A-Z(uppercase)
• a-z(lowercase)
• Alphabets from other universal languages
Alphabets
• 0-9Digits
• _ $ etc.
Special
Symbols
• n- for new line
• t for tab spaces
• b for backspace etc.
Escape
Sequences
6. ASCII & UNICODE CHARCTER SETS
We know computer understands only binary codes
i.e. codes of 0’s and 1’s.
So numbers like 65,32,46 etc. can be converted to
binary code. e.g.
65 10(100001)2
7. ASCII AND UNICODE CHARCTER SETS
You might be thinking how can we convert letters like
ABCDEF…. into binary code.
Every single key on the keyboard has number associated
to it
If we press `A` then its decimal ASCII code is 65.Now we
can convert decimal to binary to make it computer
readable and understandable.
65 10(100001)2
ASCII supports 128 characters
ranging from 0-127
ASCII takes 1 byte of memory
space
9. ASCII AND UNICODE CHARCTER SETS
ASCII Codes can represent 128 characters (alphabets(a-
z, A-Z), digits(0-9), symbols, escape sequences)
But we know that java supports alphabets and symbols
from other languages too like Greek , Arabic, Armenian
etc.
To support characters from all the languages UNICODE
Character set is used.
Unicode can support up to 256 character codes ranging
from 0-255.
First 0-127 character codes are same as that of ASCII
codes.
UNICODE takes 2 bytes of memory space.
10. ASCII AND UNICODE CHARCTER SETS
UNICODES
Unicode can support up
to 256 character codes
ranging from
0-255.
First 0-127 character
codes are same as that
of ASCII codes.
