c - 如何比较两个多维数组

Question

我有两个多维数组

num[line][col] = {
        { '\0', '1', '\0', '\0', '\0' },
        { '\0', '\0', '\0', '3', '\0'  },
        };  
solution[line][col] = {
        { '5', '1', '3', '4', '2' },
        { '4', '2', '5', '3', '1'  },};

1. 如何写 num ？ 2.如何比较num和solution？ 非常感谢

尝试使用memcmp来比较num和解决方案:

char num[line][col] = {
    { '\0', '1', '\0', '\0', '\0' },
    { '\0', '\0', '\0', '3', '\0'  },
    };  
char solution[line][col] = {
    { '5', '1', '3', '4', '2' },
    { '4', '2', '5', '3', '1'  }, };

int main(void)
{
    printf("Comparing num[][] to solution[][]...\n");
    int result = memcmp(num, solution, 10);

    if (result != 0)
        printf("Not equal.\n");
    else
        printf("Equal.\n");

    return 0;
}
