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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 |
#include<stdio.h> int main() { int a[5][5],i,j,m,n; printf("How many rows?"); scanf("%d",&n); printf("How many columns?"); scanf("%d",&m); printf("\nEnter the matrix:\n"); for(i=0;i<m;++i) for(j=0;j<n;++j) scanf("%d",&a[i][j]); printf("\nTranspose of given matrix:\n"); for(i=0;i<m;++i) { for(j=0;j<n;++j) printf("%d ",a[j][i]); printf("\n"); } return 0; } |

**Output**

*How many rows?3*

*How many columns?3*

*Enter the matrix:*

*1 2 3*

*4 5 6*

*7 8 9*

*Transpose of given matrix:*

*1 4 7*

*2 5 8*

*3 6 9*
