结构和其他数据形式 指向结构的指针

 

#include<stdio.h>
#define LEN 20

struct names{
       char first[LEN];
       char last[LEN];

struct guy{
       struct names handle;

    };
    struct guy *him;//指向结构的指针
    him = &fellow[0];//必须使用取地址符号，结构名不是地址！与数组不同
    printf("address #1:%p #2:%p\n",&fellow[0],&fellow[1]);
    printf("pointer #1:%p #2:%p\n",him,him+1);
    printf("$%.2f\n$%.2f\n",him->income,(*him).income);//两种方式获得 ，必须使用圆括号
    him++;//自增后，地址增加的字节数是一个结构单位的字节数大小
    printf("%s\n%s",him->favfood,him->handle.last);
    getchar();
    return 0;
