The document discusses the relational model for databases. The relational model represents data as mathematical n-ary relations and uses relational algebra or relational calculus to perform operations. Relational calculus comes in two flavors: tuple relational calculus (TRC) and domain relational calculus (DRC). TRC uses tuple variables while DRC uses domain element variables. Expressions in relational calculus are called formulas and queries return tuples that make the formula evaluate to true.
Functions allow programmers to break programs into smaller, reusable parts. There are two types of functions in C: library functions and user-defined functions. User-defined functions make programs easier to understand, debug, test and maintain. Functions are declared with a return type and can accept arguments. Functions can call other functions, allowing for modular and structured program design.
Structures in C allow the user to define a custom data type that combines different data types to represent a record. A structure is similar to an array but can contain heterogeneous data types, while an array only holds the same type. Structures are defined using the struct keyword followed by structure tags and member lists. Structure variables are declared like other variables and members can be accessed using the dot operator. Arrays of structures and nested structures are also supported.

FUNCTION IN C PROGRAMMING UNIT -6 (BCA I SEM)Mansi Tyagi
A function is a block of code that performs a specific task. There are two types of functions: library functions and user-defined functions. User-defined functions are created by the programmer to perform specific tasks within a program. Recursion is when a function calls itself during its execution. For a recursive function to terminate, it must have a base case and each recursive call must get closer to the base case. An example is a recursive function to calculate the factorial of a number. Storage classes determine where variables are stored and their scope. The main storage classes are automatic, register, static, and external.

The document discusses different types of linked lists including:
- Singly linked lists that can only be traversed in one direction.
- Doubly linked lists that allow traversal in both directions using forward and backward pointers.
- Circular linked lists where the last node points back to the first node allowing continuous traversal.
- Header linked lists that include a header node at the beginning for simplified insertion and deletion. Header lists can be grounded where the last node contains a null pointer or circular where the last node points to the header.
- Two-way or doubly linked lists where each node contains a forward and backward pointer allowing bidirectional traversal through the list.
A combinational circuit is a logic circuit whose output is solely determined by the present input. It has no internal memory and its output depends only on the current inputs. A half adder is a basic combinational circuit that adds two single bits and produces a sum and carry output. A full adder adds three bits and produces a sum and carry like the half adder. Other combinational circuits discussed include half and full subtractors, decoders, encoders, and priority encoders.
Pointer is a variable that stores the memory address of another variable. Pointers allow accessing and modifying the value of the variable being pointed to using dereferencing operator (*). Pointer variables have their own memory address. Array names act as pointers to the first element of the array. Pointer arithmetic can be used to access elements of an array using pointers. NULL is a special value used to indicate an empty or uninitialized pointer.
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.
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.
The document discusses linked lists, which are a linear data structure consisting of nodes connected to each other via pointers. Each node contains data and a pointer to the next node. There are several types of linked lists including singly linked lists where each node has a next pointer, doubly linked lists where each node has next and previous pointers, and circular linked lists where the last node points to the first node. The document covers terminology, advantages and disadvantages, operations, and implementations of different types of linked lists such as dynamic vs static memory allocation and uses in applications.
The document discusses different data types in C programming language including primary, derived, and user-defined data types. It explains what structures are and how to define, declare, and access structure variables. Structures allow grouping of different data types under a single name to represent complex user-defined data types like a record. The document provides examples of defining simple and nested structures, arrays of structures, and accessing structure members using pointers. It also discusses some common programming problems that can be solved using structures.
Contiguous buffer is what makes code run fast. With the regular and compact layout, data can go through the memory hierarchy in a quick way to the processor. Numpy makes use of it to achieve the runtime almost as fast as C.
However, not all algorithms can be easily maintained or designed by using array operations. A more general ways is to use the contiguous buffer as an interface. The dynamic typing system of Python makes it easy to use but hard to optimize. The typed, fixed-shape buffer allows efficient data sharing between the fast code written in C++ and the Python application. In the end, the system is as easy to use as but much faster than Python. The runtime is the same as C++.
In this talk, I will show how to design a simple array system in C++ and make it available in Python. It may be made as a general-purpose library, or embedded for ad hoc optimization.
Pointer is a variable that stores the address of another variable. Pointers in C are used to allocate memory dynamically at runtime and can point to data of any type such as int, float, char, etc. Pointers are declared with a * before the variable name and are initialized using the address operator &. Pointers can be used to pass arguments to functions by reference and can also point to elements within structures.

Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.
Harnessing WebAssembly for Real-time Stateless Streaming PipelinesChristina Lin
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.

The CBC machine is a common diagnostic tool used by doctors to measure a patient's red blood cell count, white blood cell count and platelet count. The machine uses a small sample of the patient's blood, which is then placed into special tubes and analyzed. The results of the analysis are then displayed on a screen for the doctor to review. The CBC machine is an important tool for diagnosing various conditions, such as anemia, infection and leukemia. It can also help to monitor a patient's response to treatment.

Sinan from the Delivery Hero mobile infrastructure engineering team shares a deep dive into performance acceleration with Gradle build cache optimizations. Sinan shares their journey into solving complex build-cache problems that affect Gradle builds. By understanding the challenges and solutions found in our journey, we aim to demonstrate the possibilities for faster builds. The case study reveals how overlapping outputs and cache misconfigurations led to significant increases in build times, especially as the project scaled up with numerous modules using Paparazzi tests. The journey from diagnosing to defeating cache issues offers invaluable lessons on maintaining cache integrity without sacrificing functionality.
Electric vehicle and photovoltaic advanced roles in enhancing the financial p...IJECEIAES
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
5. Structure Initialization
struct st_record
{
int weight;
float height;
} student1 = (60, 180.75);
main()
{
struct st_record student2 = (53, 170.60);

Another method is to
initialize a structure
variable outside the
function
6. Structure Initialization
1. We cannot initialize individual members inside
the structure template.
2. The order of values enclosed in braces must
match the order of members in the structure
definition.
3. It is permitted to have a partial initialization.
4. The uninitialized members will be assigned
default values as follows:
• Zero for integer and floating point numbers
• ‘0’ for characters and strings

7. Structure Initialization
• Two variables of the same structure type can
be copied the same way as ordinary variables.
person1 = person2;
person2 = person1;
• C does not permit any logical operations on
structure variables.
person1 == person2
person1 != person2

8. Accessing members
Consider the following structure:
typedef struct
{
int x;
int y;
} VECTOR;
VECTOR v, *ptr;
ptr = &v;

9. Accessing members
The identifier ptr is known as pointer that has
been assigned the address of the structure
variable v. Now the members can be accessed in
the following three ways:
• using dot notation : v.x
• using indirection notation : (*ptr).x
• using selection notation : ptr x

10. Pointers and Structures
struct inventory
{
char name[30];
int number;
float price;
} product[2], *ptr;
This statement declares product as an array of two
elements, each of the type struct inventory and ptr as a
pointer to data objects of the type struct inventory.
Computer Programming –
Pankaj Debbarma, TIT, Narsingarh

11. Pointers and Structures
The assignment
ptr = product;
would assign the address of the zeroth element
of product to ptr. That is, the pointer ptr will
now point to product[0]. Its member can be
accessed using
ptr name
ptr number
ptr price

12. Structures and Functions
There are three methods by which values of a
structure can be transferred from one function
to another.
1. Pass each member of the structure as an
actual argument of the function call.
2. Passing a copy of the entire structure to the
called function.
3. The address location of the structure is
passed to the called function.

14. Unions
During accessing, we should make sure that we
are accessing the member whose value is
currently stored. For example, the statements
such as
code.m = 379;
code.x = 7859.36
printf(“%d”, code.m)
would produce erroneous output

15. Unions
Unions may be initialized when the variable is
declared. But, unlike structures, it can be
initialized only with a value of the same type as
the first union member.
union item abc = {100};
is valid but the declaration
union item abc = {10.75};
is invalid

16. Size of Structures
The expression
sizeof(struct x)
will evaluate the number of bytes required to hold
all the members of the structure x. If y is a simple
structure variable of type struct x, then
sizeof(y);
would also give the same answer. However, if y is an
array variable of type struct x, then it would give
the total number of bytes the array y requires.

17. Size of Structures
This kind of information would be useful to
determine the number of records in a database.
For example, the expression
sizeof(y) / sizeof(x)
would give the number of elements in the array
y.
