这是我写的重载运算符的小程序但是有错误，希望大家帮忙看一下。谢谢！
#include<iostream>
using namespace std;
class Point {
private:int m;
public: Point(int a){m=a;}
Point operator ++(int){ Point point=*this;
++( *this);
return point;}
Point operator --(int){Point point=*this;
--(*this);
return point;}
};
void main(){
int m;
cout<<"please enter your numbaer:"<<endl;
cin>>m;
Point point(m);
cout<<"point++"<<point++<<endl<<"point--:"<<point--<<endl;
}
错误调试：

11.cpp
D:\学习文件\CL\8-10\11\11.cpp(7) : error C2675: unary '++' : 'class Point' does not define this operator or a conversion to a type acceptable to the predefined operator

执行 cl.exe 时出错.

11.obj - 1 error(s), 0 warning(s)

Point operator ++(int){
++(this.m);
return this;}
Point operator --(int){
--(this.m);
return this;}
再重载“<<";

能写详细点吗 ？我对运算符重载不太会，希望你能帮我一下！谢谢版主啦！麻烦你了！

cout<<"point++"<<point++<<endl<<"point--:"<<point--<<endl;
}
这里没有<<运算符
另外Point operator ++(int){ Point point=*this;
++( *this);这是什么??你不是正在做这个么???
2楼对了
