为什么输出结果不是10,怎么回事10001呢
#include <iostream>
using namespace std;
int main()
{
struct date
{
int year;
int month;
int day;
};
//定义baby结构
struct baby
{
int num;
float weight;
date birthday;//date 为结构类型
};
//声明结构变量并初始化
baby b1 = { 10001,10,{2002,12,25} };
//下列是baby结构变量b1的引用
cout << "b1.num=" << b1.num << endl;
cout << "b1.weight=" << b1.num << endl;
cout << "b1.birthday.year=" << b1.birthday.year << endl;
cout << "b1.birthday.month=" << b1.birthday.month << endl;
cout << "b1.birthday.day=" << b1.birthday.day << endl;
cout << "___________________________________________" << endl;
//声明baby结构变量temp,并进行赋值运算
baby temp;
temp = b1;
cout << "temp.num=" << temp.num << endl;
cout << "temp.weight=" << temp.num << endl;
cout << "temp.birthday.year=" << temp.birthday.year << endl;
cout << "temp.birthday.month=" << temp.birthday.month << endl;
cout << "temp.birthday.day=" << temp.birthday.day << endl;
}
