How a write a global non member post decremented overloaded operator?

Question

I am beginning to programming. I am stuck in this point so I hope you guys will help me.

When we write a post decrement member function the syntax for that is

     type type::operator--(int){}

But I want this to be a friend function so how can i write it?

This is for pre increment:

   friend Mystring &operator--(  Mystring &lhs);

What is the syntax for post incrementation?

You should make it a member function: https://stackoverflow.com/questions/4421706/what-are-the-basic-rules-and-idioms-for-operator-overloading — NathanOliver, Dec 05 '18 at 13:31

Try like this:

class type
{
// ...
    // postfix operator--
    friend type operator--(type &t, int){type t1; /* some logics */ return t1;}
};
