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.


Program to Find the Transpose of a Matrix

#include 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
