#include<iostream>

using namespace std;

class Student{

private:

string m_strName;

int m_iAge;

public:

Student() :m_strName("Name"), m_iAge(1){

cout << "初始化列表0" << endl;

}

Student(string name,int age):m_strName(name), m_iAge(age){

cout << "初始化列表" << endl;

}

void getName(){

cout << m_strName << endl;

}

void getAge(){

cout << m_iAge << endl;

}

};

int main(){

Student s1("Cjj",12);

s1.getName();

Student s2();

s2.getName();

}

//s2.getName(); 報錯?expession must have class type.

這是為什么....
