advantages of 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: c++ over load operator

// This will substract one vector (math vector) from another
// Good example of how to use operator overloading

vec2 operator - (vec2 const &other) {
    return vec2(x - other.x, y - other.y);
}
