面向对象设计C---重载运算符++ 实验上（三十四）

实现前++

#include <iostream>
#include <cstring>

using namespace std;

class Cvector
{
public:
    Cvector(int m,int n);
    Cvector operator++();

    void output();
private:
    int x;
    int y;
};

Cvector::Cvector(int m,int n)
{
    x=m;
    y=n;
}

void Cvector::output()
{
    cout<<x<<","<<y<<endl;
}

Cvector Cvector::operator++()
{
    ++this->x;
    ++this->y;
    return (*this);
}
int main()
{
    Cvector v(0,0);
    Cvector tmp= ++v;
    v.output();
   tmp.output();

    return 0;
}
