C++函数 - struct结构体学习
在结构体中，定义初始化函数:
DETAILS
#include<iostream>
#include<stdio.h>
#include<string>
using namespace std;
struct userInfo
{
string userName;
int age;
string address;
userInfo():
userName("null"),
age(0),
address("null")
{}
userInfo(const string& m_userName,int m_age,const string& m_address):
userName(m_userName),
age(m_age),
address(m_address)
{}
};
struct Day
{
explicit Day(int d)
:val(d)
{}
int val;
};
int main()
{
userInfo m_userInfo("jason",26,"Nanjing");
Day m_Day(20.2);
printf("userInfo userName:%s,age:%d,address:%s\n",m_userInfo.userName.c_str(),m_userInfo.age,m_userInfo.address.c_str());
printf("m_Day:%d\n",m_Day.val);
return 0;
