Transpose of a Matrix in C

C Program to find the Transpose of a Matrix

  • In this problem, we are to find the transpose of an input matrix.
  • Transpose of a matrix is obtained by interchanging rows and columns. In other words, transpose of A[][] is obtained by changing A[i][j] to A[j][i].
#include <stdio.h>
int main ()
{
    int a[10][10], t[10][10], r, c, i, j;
    printf ("Enter the order of matrix: ");
    scanf ("%d %d", &r, &c);

    printf ("\nEnter the elements of matrix:\n");
    for (i = 0; i < r; ++i)
    {
        for (j = 0; j < c; ++j)
	    {
	        printf ("Enter the element a[%d %d]: ", i + 1, j + 1);
	        scanf ("%d", &a[i][j]);
	    }
    }
  
    printf ("\nInput Matrix: \n");
    for (i = 0; i < r; ++i)
    {
        for (j = 0; j < c; ++j)
	    {
	        printf ("%d ", a[i][j]);
	        if (j == c - 1)
	            printf ("\n\n");
	    }
    }

    for (i = 0; i < r; ++i)
    {
        for (j = 0; j < c; ++j)
	    {
	        t[j][i] = a[i][j];
	    }
    }

    printf ("\nTranspose of the Input Matrix:\n");
    for (i = 0; i < c; ++i)
    {
        for (j = 0; j < r; ++j)
	    {
	        printf ("%d ", t[i][j]);
	        if(j == r - 1)
	           printf ("\n\n");
	    }
    }
    return 0;
}
