This program takes a matrix of order r*c from the user and computes the transpose of the 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 <iostream>
using namespace std;
int main()
{
int a[10][10], trans[10][10], r, c, i, j;
cout << "Enter rows and columns of matrix: ";
cin >> r >> c;
// Storing element of matrix entered by user in array a[][].
cout << endl << "Enter elements of matrix: " << endl;
for(i = 0; i < r; ++i)
for(j = 0; j < c; ++j)
{
cout << "Enter elements a" << i + 1 << j + 1 << ": ";
cin >> a[i][j];
}
// Displaying the matrix a[][]
cout << endl << "Entered Matrix: " << endl;
for(i = 0; i < r; ++i)
for(j = 0; j < c; ++j)
{
cout << " " << a[i][j];
if(j == c - 1)
cout << endl << endl;
}
// Finding transpose of matrix a[][] and storing it in array trans[][].
for(i = 0; i < r; ++i)
for(j = 0; j < c; ++j)
{
trans[j][i]=a[i][j];
}
// Displaying the transpose,i.e, Displaying array trans[][].
cout << endl << "Transpose of Matrix: " << endl;
for(i = 0; i < c; ++i)
for(j = 0; j < r; ++j)
{
cout << " " << trans[i][j];
if(j == r - 1)
cout << endl << endl;
}
return 0;
}
```

**Output**

Enter rows and column of matrix: 2 3 Enter elements of matrix: Enter elements a11: 1 Enter elements a12: 2 Enter elements a13: 9 Enter elements a21: 0 Enter elements a22: 4 Enter elements a23: 7 Entered Matrix: 1 2 9 0 4 7 Transpose of Matrix: 1 0 2 4 9 7
