C Program to Find Transpose of a Matrix

Transpose of a matrix is obtained by changing rows to columns and columns to rows. In other words, transpose of A[][] is obtained by changing A[i][j] to A[j][i].

C Program to Find Transpose of a Matrix

	
#include <stdio.h>
int main() {
    int a[10][10], transpose[10][10], r, c;
    printf("Enter rows and columns: ");
    scanf("%d %d", &r, &c);

    printf("\nEnter matrix elements:\n");
    for (int i = 0; i < r; ++i)
    for (int j = 0; j < c; ++j) {
        printf("Enter element a%d%d: ", i + 1, j + 1);
        scanf("%d", &a[i][j]);
    }

    printf("\nEntered matrix: \n");
    for (int i = 0; i < r; ++i)
    for (int j = 0; j < c; ++j) {
        printf("%d  ", a[i][j]);
        if (j == c - 1)
        printf("\n");
    }
    
    for (int i = 0; i < r; ++i)
    for (int j = 0; j < c; ++j) {
        transpose[j][i] = a[i][j];
    }

    printf("\nTranspose of the matrix:\n");
    for (int i = 0; i < c; ++i)
    for (int j = 0; j < r; ++j) {
        printf("%d  ", transpose[i][j]);
        if (j == r - 1)
            printf("\n");
    }
    return 0;
}        
	

Output :
