# 指向结构的指针

结构指针类似于普通变量指针。

```c
#include <stdio.h>

struct point
{
    int x;
    int y;
};

int main(int argc, char const *argv[])
{
    struct point p1 = {100, 100};
    struct point *p2;
    p2 = &p1;
    printf("x: %d, y: %d.\n", p1.x, p1.y);
    printf("x: %d, y: %d.\n", p2->x, p2->y);
    printf("x: %d, y: %d.\n", (*p2).x, (*p2).y);
    return 0;
}
```
