int **a 和 int (*a)[]的区别

关于理论知识隔壁们的教程说的很详细了我就不多赘述了。我这边主要贴一段代码来看看这两种东西使用上的区别到底在哪。

#include <stdio.h>

int main(int argc, char ** argv)
{
        int a1[2] = {1,2};
        int a2[2] = {3,4};
        int b[2][2] = {5,6,7,8};

        int *p[2] = {a1,a2};
        int (*q)[2] = b;

        printf("%d",**p);
        printf("%d",*(*p+1));
        printf("%d",**(p+1));
        printf("%d",**(p+1)+1);

        printf("\n");
        printf("%d",*q[0]);
        printf("%d",*(q[0]+1));
        printf("%d",*q[1]);
        printf("%d",*(q[1]+1));
}

Out:

1234
5678
