A linked list is a fundamental data structure used in computer science to organize and store a collection of elements. Unlike arrays, linked lists do not require a contiguous block of memory and can efficiently handle dynamic memory allocation. Key Characteristics Nodes: A linked list is composed of nodes, where each …

A stack is a fundamental data structure in computer science that operates on a Last In, First Out (LIFO) principle. This means that the last element added to the stack is the first one to be removed. You can think of a stack like a stack of plates: you add new plates to the top and remove them from the top as well. Key …

A circular queue is a data structure that operates on a First-In, First-Out (FIFO) basis but with a circular arrangement. Unlike a linear queue, where elements are added at the rear and removed from the front, a circular queue connects the last position back to the first, forming a circle. This allows for efficient use …

A simple queue is a fundamental data structure that follows the First-In, First-Out (FIFO) principle. This means that the first element added to the queue will be the first one to be removed, just like people standing in line—whoever gets in first is served first. Key Operations in a Simple Queue: Enqueue (Insertion): …

An array is a data structure used in programming to store a collection of elements, typically of the same type, in a fixed-size sequence. Initialisation of Array 1#include <stdio.h> 2int main() 3{ 4 // it's not important to give size during initialisation. 5 // eg: float y[]={1.2,2,3.32}; 6 7 int g[5]; 8 int …

C is a powerful, general-purpose programming language that provides control over system resources and efficient execution. This post will cover some essential concepts in C that every programmer should understand: Control Strings, Global Variables, Strings, Switch Statements, Ternary Operators, Unformatted …

To find average of two numbers. 1#include <stdio.h> 2int main() 3{ 4 float a; 5 float b; 6 printf("give the values for a and b:\n"); 7 scanf("%f%f", &a,&b); 8 float c=(a+b)/2; 9 printf("the average of two numbers is %f\n", c); 10 return 0; 11} To find the binary equivalent of a …

Loops in C language are used to repeatedly execute a block of code based on certain conditions. They are fundamental for tasks such as iterating over arrays, processing data, and performing repetitive operations. Loops 1#include <stdio.h> 2#include <string.h> 3 4void main() 5{ 6 // loop means - to execute …

Matrices: Matrix Multiplication 1#include<stdio.h> 2int main() 3{ int m,n,p,q,a[10][10],b[10][10],c[10][10],k,i,j; 4 printf("enter the rows and column value for matrix 1:\n"); 5 scanf("%d%d",&m,&n); 6 printf("enter the rows and columns value for matrix 2:\n"); 7 …

Pointers Basics 1#include<stdio.h> 2int main() 3{ 4 int a=10; 5 printf("Address of P: %p \n", *a); 6 7 int *p; 8 9 p=&a; 10 11 *p = 30; 12 13 printf("Address of P: %p \n", p); 14 printf("Value of P: %d \n", a); 15 printf("%d", *(&a)); 16 17 18} to read the elements and …
