In this example, you will learn to find the transpose of a matrix in C programming.

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

The transpose of a matrix is a new matrix that is obtained by exchanging the rows and columns.

In this program, the user is asked to enter the number of rows
`r` and columns `c`. Their values should be less than 10 in
this program.

Then, the user is asked to enter the elements of the matrix (of order
`r*c`

).

The program below then computes the transpose of the matrix and prints 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: ");
scanf("%d %d", &r, &c);
// Assigning elements to the matrix
printf("\nEnter matrix elements:\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");
}
// 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 the 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");
}
return 0;
}
```

**Output **

Enter rows and columns: 2 3 Enter matrix elements: Enter element a11: 1 Enter element a12: 4 Enter element a13: 0 Enter element a21: -5 Enter element a22: 2 Enter element a23: 7 Entered matrix: 1 4 0 -5 2 7 Transpose of the matrix: 1 -5 4 2 0 7
