代码整理，将学过的三种运算符重载，每个至少实现一个运算符的重载

#include <iostream>using namespace std;class Cloudy
{friend bool operator!=(const Cloudy &L,const Cloudy &R);
private:int a;
public:int b;
public:Cloudy(){}Cloudy(int a,int b):a(a),b(b){}const Cloudy operator*(const Cloudy &R)const{Cloudy temp;temp.a = a * R.a;temp.b = b * R.b;return temp;}Cloudy operator*=(Cloudy &R){a *= R.a;b *= R.b;return *this;}void show(){cout << "a =" << a << " " << "b =" << b << endl;}
};bool operator!=(const Cloudy &L,const Cloudy &R)
{if(L.a != R.a || L.b != R.b){return true;}else{return false;}
}int main()
{Cloudy c1(11,45);Cloudy c2(14,45);Cloudy c3;c3 = c2 * c1;c3.show();if(c1 != c2){cout << "c1 != c2" << endl;}c3 *= c1;c3.show();return 0;
}
