This program takes a matrix of order r*c from the user and computes the transpose of that matrix.

To understand this example, you should have the knowledge of following C programming topics:

In this program, user is asked to entered 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;
}
```

**Output**

Enter rows and columns of matrix: 2 3 Enter element of matrix: Enter element a11: 2 Enter element a12: 3 Enter element a13: 4 Enter element a21: 5 Enter element a22: 6 Enter element a23: 4 Entered Matrix: 2 3 4 5 6 4 Transpose of Matrix: 2 5 3 6 4 4
