Transpose of a Matrix in C

In this tutorial, we are going to see how to transpose a matrix in C. It is done by swapping rows and columns of a matrix. For example, let’s consider the following 3 X 2 matrix:
 

 

Transpose of a Matrix in C

#include <stdio.h>

void main()
{
    int matrix[10][10], transpose[10][10];
    int i,j,n,m;
  
    printf("Enter the number of rows and columns:\n");
    scanf("%d%d",&n,&m);
  
    printf("Enter the matrix elements\n");
    for(i = 0; i < n; i++)
    {
        for(j = 0; j < m; j++)
        {
            scanf("%d", &matrix[i][j]);
        }
    }

    printf("Matrix:\n");
    for(i = 0; i < n; i++)
    {
        for(j = 0; j < m; j++)
        {
            printf("%d\t", matrix[i][j]);
        }
        printf("\n");
    }
    //Transposition
    for(i = 0; i < n; i++)
    {
        for(j = 0; j < m; j++)
        {
            transpose[j][i] = matrix[i][j];
        }
    }

    printf("The transposition of the matrix:\n");
    for(i = 0; i < m; i++)
    {
        for(j = 0; j < n; j++)
        {
            printf("%d\t", transpose[i][j]);
        }
        printf("\n");
    }
}

Output:

Enter the number of rows and columns:
3 2
Enter the matrix elements
1 2
2 4
5 6
Matrix:
1       2
2       4
5       6
The transposition of the matrix:
1       2       5
2       4       6
