C Coding to Perform Matrix Multiplication -
C program, using recursion, performs Matrix multiplication of two matrices and displays the result. Use 2D array to represent a matrix and resulting matrix is stored in a different...

Check Whether Two Strings are Anagrams -
Program takes two strings as input & checks whether two strings are anagrams. Take two strings as input and store them in the arrays array1[] array2[] respectively. In the function

Representation of Graph by Incidence List -
This algorithm takes the input of the number of 'vertex and edges'. Then it takes the input of connected vertex pairs. Print the incidence list representation of the graph. And for each

Find Frequency of Each Character in String -
C Program code to 'Count Frequency' of each character in a string Using Loop. There are so many algorithms to Count Frequency of each character. Here I'm explaining the easiest one

Sort Elements Using Quick Sort Algorithm -
Two stacks to store two ends of the list in C. Entering elements in the array. Set top to stack. To print the sorted array. Enter the no of elements in the array. Enter the elements

C++ Program to Implement Vector in STL -

Prints Day Name of Week Array Constant -
Input week day number from user. Store it in a variable say week. Print Monday if week=1. I have assumed Monday as first day of week. And check condition for all 7 days & print the

Linear Search Algorithm in C++ Language -
In case of 'an array' we check that a given key or a number is present in array at any index or not by "comparing each element" of array. By traversing the whole data structure elements
