Split 2d array into chunks in c++

int main(int agrc, char *argv[])
{
    const size_t w = 8;
    const size_t h = 3;
    const size_t c = 2;

    int mat[h][w] = {
        { 1, 2, 3, 4, 5, 6, 7, 8 },
        { 1, 2, 3, 4, 5, 6, 7, 8 },
        { 1, 2, 3, 4, 5, 6, 7, 8 }
    };

    int chunks[w / c][h][c];

    split(h, w, mat, c, chunks);

    for (int i = 0; i < w / c; i++) {
        for (int j = 0; j < h; j++) {
            for (int k = 0; k < c; k++) {
                printf("%3d ", chunks[i][j][k]);
            }
            printf("\n");
        }
        printf("\n\n");
    }

    return 0;
}
