Count Even Numbers in 3D Array Program Code

#include <stdio.h>
int main() {
    int arr[2][3][4], i, j, k;
    int evenCount = 0;
    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++)

                if(arr[i][j][k] % 2 == 0)
                    evenCount++;
    
    printf("Total elements: %d\n", layers*rows*cols);
    printf("Even numbers: %d\n", evenCount);
