C++DAY06

01. 复习

各种重载：

? 1.1 指针运算符重载
? 1.2 复制运算符重载

02. 其他运算符重载

?2.1 逻辑运算符重载
? == != >= <=

#include <iostream>
#include <string>
using namespace std;

class Person{
public:
    Person(string name, int age):m_Name(name), m_Age(age){}
    
    bool operator==(Person &p)
    {
        if(this->m_Name == p.m_Name && this->m_Age == p.m_Age)
            return true;
        return false;
    }
    
private:
    string m_Name;
    int m_Age;
};

void test01()
{
    Person p1("Tom", 10);
    Person p2("Tom", 10);
    
    if(p1 == p2)
        cout << "p1 和 p2相等" << endl;
    else
        cout << "p1 和 p2不等" << endl;
}

int main(void)
{
    test01();
    
    return 0;
}

?2.2 函数调用运算符重载

#include <iostream>
#include <string>
using namespace std;

class MyPrint{
public:
    void operator()(string text)
    {
        cout << text << endl;
    }
};

void test01()
{
    MyPrint myprint;
    myprint("hello world!");
}

class MyAdd{
public:
    int operator()(int v1, int v2)
    {
        return v1+v2;
    }

};

void test02()
{
    MyAdd myadd;
    //cout<<myadd(1, 2)<<endl; 
    cout<<MyAdd()(1, 2)<<endl; //匿名对象
}

int main(void)
{
    //test01();
    test02();
    
    return 0;
}

test
