结构体的嵌套使用

c

先上代码！

#include<stdio.h>
#include<stdlib.h>//包含了system("pause")
#define LEN 20
struct names{
    char first[LEN];
    char last[LEN];
};
struct guy{
    struct names handle;//结构体嵌套
    char favfood[LEN];
    char job[LEN];
    float income;
};
int main(void)
{
    struct guy fellow[2]={  //结构数组的初始化
        {{"Ewen","Villard"},
        "grilled salmon",
        "personality coach",
        58112.00
        },
        {{"Rodney","Swillbelly"},
        "tripe",
        "tabloid editor",
        232400.00
        }
    };
    struct guy * him;/*这是一个指向结构的指针 */
    printf("address #1: %p #2: %p\n", &fellow[0],&fellow[1]);
    him  = &fellow[0]; /*告诉该指针它要指向的地址*/
    printf("pointer #1: %p #2: %p\n", him,him + 1);
    printf("him->income is $%.2f: (*him).income is $%.2f\n",him->income,(*him).income);
    him++;//指向下一个结构
    printf("him->favfood is %s: him->handle.last is %s\n",him->favfood,him->handle.last);
    system("pause");
    return 0;
}

用指针访问结构体成员
him->income
(*him).income
上面这两句话是一个意思，这里出现一个新的运算符->,意思是通过指针him指向结构体的incume成员
