Linear Search in C

Array

Here you will find program for linear search in C. Linear search is the simplest searching algorithm which is sometimes known as sequential search. In this algorithm each element of array is compared with the targeted element sequentially. Linear Search in C #include<stdio.h> int main() { int a[20],i,x,n; printf(“How many elements?”); scanf(“%d”,&n); printf(“Enter array elements:\n”); …

Transpose of Matrix in C

Array

Here is the program for transpose of matrix in C. We first read a matrix of size mxn and then find its transpose by just interchanging the rows and columns i.e. rows become columns and columns become rows. Transpose of Matrix in C #include<stdio.h> int main() { int a[5][5],i,j,m,n; printf(“How many rows?”); scanf(“%d”,&n); printf(“How many …
