Find Sum of Each Column in 3D Array Program Code

#include <stdio.h>
int main() {
    int arr[2][3][4], i, j, k;
    int layers=2, rows=3, cols=4;
    
    for(i =0;i<layers;i++)
        for(j =0;j<rows;j++)
            for(k =0;k<cols;k++)
                arr[i][j][k] = i*100 + j*10 + k;
    
    for(i =0;i<layers;i++)
        for(k =0;k<cols;k++) {
            int colSum = 0;
            for(j =0;j<rows;j++)
                colSum += arr[i][j][k];
            printf("Layer %d, Col %d sum = %d\n", i, k, colSum);
        }
    return 0;
