#include <stdio.h>
#include <stdlib.h>


int main()
{
    struct point
    {
        int x, y;
    };

    struct rectangle
    {
           struct point upper_left, lower_right;
    };

    struct rectangle *p = malloc(sizeof(struct rectangle));

    p->upper_left = {10,25};

    return 0;
}

这给出：
