C Program to Find Transpose of a Matrix?

In this program, the user is asked to enter the number of rows r and columns c. The value of r  and c should be less than 10 in this program. The user is asked to enter elements of the matrix (of order r*c). Then, the program computes the transpose of the matrix and displays it on the screen.

#include <stdio.h>

int main()

{

    int a[10][10], transpose[10][10], r, c, i, j;

    printf("Enter rows and columns of matrix: ");

    scanf("%d %d", &r, &c);

    // Storing elements of the matrix

    printf("\nEnter elements of matrix:\n");

    for(i=0; i<r; ++i)

        for(j=0; j<c; ++j)

        {

            printf("Enter element a%d%d: ",i+1, j+1);

            scanf("%d", &a[i][j]);

        }

    // Displaying the matrix a[][] */

    printf("\nEntered 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");

        }

 // Finding the transpose of matrix a

    for(i=0; i<r; ++i)

        for(j=0; j<c; ++j)

        {

            transpose[j][i] = a[i][j];

        }

  // Displaying the transpose of matrix a

    printf("\nTranspose of Matrix:\n");

    for(i=0; i<c; ++i)

        for(j=0; j<r; ++j)

        {

            printf("%d  ",transpose[i][j]);

            if(j==r-1)

                printf("\n\n");

        }    return 0;
