transpose of a matrix cpp code example

Example: transpose of a matrix in c++

#include <stdio.h>
#define N 4
 
// This function stores transpose of A[][] in B[][]
void transpose(int A[][N], int B[][N])
{
    int i, j;
    for (i = 0; i < N; i++)
        for (j = 0; j < N; j++)
            B[i][j] = A[j][i];
}
 
int main()
{
    int A[N][N] = { {1, 1, 1, 1},
                    {2, 2, 2, 2},
                    {3, 3, 3, 3},
                    {4, 4, 4, 4}};
 
    int B[N][N], i, j;
 
    transpose(A, B);
 
    printf("Result matrix is \n");
    for (i = 0; i < N; i++)
    {
        for (j = 0; j < N; j++)
           printf("%d ", B[i][j]);
        printf("\n");
    }
 
    return 0;
}
