后、前++操作符重载

#include<iostream>
using namespace std;
class test{
int mvalue;
public:
        test(int i){
                mvalue = i;
        }
        int value(){
                return mvalue;
        }
        test& operator++(){
                ++mvalue;
                return *this;
        }
        //后++
        test operator++(int){
                //临时对象
                test ret(mvalue);
                mvalue++;
                return ret;
        }
};
int main(){
        test t(0);
        test tt = t++;

        cout << tt.value() << endl;
        cout << t.value() << endl;
        return 0;
}
//运行结果
