Use of unary plus operator

Question

I\'ve heard it is used as overloaded operator+ for example

class MyClass
{
    int x;
public:
    MyClass(int num):x(num){}
    MyClass operator+(const MyCla         


        

Answer 1

This is not overloading and using unary + .. You need to either make that a free function or make the member function take 0 arguments

class MyClass
{
    int x;
public:
    MyClass(int num):x(num){}
    MyClass operator+() const
    {
        return *this;
    }
};

int main() {
  MyClass x = 42;
  + x;
}
