结构体和函数
结构体是一种数据类型，作为数据类型，它就可以定义变量，同时也可以作为函数的形式参数，或者让函数的返回值为一个结构体类型。下面通过一个代码来说明这一点：
#include <iostream>
using namespace std;
struct people
{
int weight;
int tall;
bool sex;
int age;
};
const int class=60;
people &sum(people1,people2);
void show(people);
int main()
{
people a=(80,190,1,19);
people b=(90,200,1,21);
people *number=&total(a,b);
cout<<"两人总计为："<<endl;
show(*number);
delete number;
return 0;
}
people &sum(people t1,people t2)
{
people *total=new people;
total->tall=t1.tall+t2.tall;
total->weight=t1.weight+t2.weight;
return *total;
}
void show(people t3)
{
cout<<t3.tall<<endl;
}
