C 结构体

基本应用

#include <iostream>
using namespace std;
struct Student
{
    string name;
    int old;
};
int main()
{
    //方式一
    Student stu;
    stu.name = "夏明";
    stu.old = 12;
    cout <<"姓名:" << stu.name<<",年龄:"<<stu.old<< endl;
    //方式二
    Student stu2 = {
        "小米"
        ,13
    };
    cout <<"姓名:" << stu2.name<<",年龄:"<<stu2.old<< endl;
    return 0;
}

姓名:夏明,年龄:12 姓名:小米,年龄:13

指针和结构体

#include <iostream>
using namespace std;
struct Student
{
    string name;
    int old;
};
int main()
{
    Student stu;
    stu.name = "夏明";
    stu.old = 12;
    Student *pStu = &stu;
    cout <<"姓名:" << pStu->name<<",年龄:"<<pStu->old<< endl;
    return 0;
}

姓名:夏明,年龄:12
