Another Demo: Overload the == and && relative to MyClass class.

 

#include <iostream>
using namespace std;

class MyClass {
  int x, y; 
public:
  MyClass() { 
     x=0; 
     y=0; 
  }

  MyClass(int i, int j) { 
     x=i; 
     y=j; 
  }
  void getXY(int &i, int &j) { 
     i=x; 
     j=y; 
  }
  int operator==(MyClass object2);
  int operator&&(MyClass object2);
};

// Overload the == operator for MyClass.
int MyClass::operator==(MyClass object2)
{
  return x==object2.x && y==object2.y; 
}

// Overload the && operator for MyClass.
int MyClass::operator&&(MyClass object2)
{
  return (x && object2.x) && (y && object2.y);
}
 
int main()
{
  MyClass object1(10, 10), object2(5, 3), object3(10, 10), object4(0, 0);

  if(object1==object2) 
     cout << "object1 same as object2\n";
  else 
     cout << "object1 and object2 differ\n";

  if(object1==object3) 
     cout << "object1 same as object3\n";
  else 
     cout << "object1 and object3 differ\n";

  if(object1 && object2) 
     cout << "object1 && object2 is true\n";
  else 
     cout << "object1 && object2 is false\n";

  if(object1 && object4)
