C++基础六-结构体

/*C/C++ 数组允许定义可存储相同类型数据项的变量,但是结构是 C++ 中另一种用户自定义的可用的数据类型,它允许您存储不同类型的数据项。*/
#include <iostream>
#include <string>

//1.定义结构体

struct Food { string name; int price; };
struct Member { string name; int age; int score; struct Food f1; };

void Printstruct(Member m) { cout <<"函数中"<< m.name <<endl; };


int main() {
    //2.结构体创建,通过(.)赋值与访问。
    //2.1

    //2.2
    struct Member m2 = { "mick",19,60 };
    cout << m1.name << endl;
    cout << m2.name << endl;
    cout << endl;


    /*3.结构体数组*/
