c语言中求三维数组元素的和（2、4、3）。

#include <stdio.h>

int main(void)
{
    int i, j, k;
    int v[2][4][3] = {{{74,58,96},{14,25,36},{45,65,74},{45,56,96}},{{74,58,36},{45,65,23},{45,56,23},{14,23,26}}};
    int sum[4][3];
    
    for (i = 0; i < 4; i++)
    {
        for (j = 0; j < 3; j++)
        {
            sum[i][j] = 0;
            for (k = 0; k < 2; k++)
            {
                sum[i][j] += v[k][i][j];
            }
        }
    }
    for (i = 0; i < 2; i++)
    {
        printf("%dst dimention: \n", i + 1);
        for (j = 0; j < 4; j++)
        {
            for (k = 0; k < 3; k++)
            {
                printf("%4d", v[i][j][k]);
            }
            putchar(‘\n‘);
        }
    }
    puts("sum: ");
    for (i = 0; i < 4; i++)
    {
        for (j = 0; j < 3; j++)
        {
            printf("%4d", sum[i][j]);
        }
        putchar(‘\n‘);
    }
    return 0;
}
