discuss about operator overloading in c++ code example

Example 1: operator overloading in c++ <<

ostream &operator<<(ostream &output, const MyClass &myObject)
{ 
  output << "P : " << myObject.property;
  return output;            
}

Example 2: operator = overloading c++

inline bool operator==(const X& lhs, const X& rhs){ /* do actual comparison */ }
inline bool operator!=(const X& lhs, const X& rhs){ return !(lhs == rhs); }
