[C]指针与结构变量

 

//pointer to structure
#include <stdio.h>

struct Person
{
    char name[10];
    char character[20];
    int age;
};

void display(struct Person *t);

int main()
{
    struct Person man = {"jerry", "fastidious", 45};
    display(&man); //取地址,与数组不一样,数组名就是地址,不需要取地址符号&
    return 0;
}

void display(struct Person *t)
{
    printf("My name is %s, I'm %d years old. And my friends always complain I'm so %s.\n", t->name, t->age, t->character);
    //or:
    // printf("My name is %s, I'm %d years old. And my friends always complain I'm so %s.\n", (*t).name, (*t).age, (*t).character);
}
