Is it possible to overload the postfix form of the ++ operator without using classes?

Question

C++ / C#

I want to overload the postfix form of the ++ operator for a variable of type string.

Tried like this:

the code

string operator ++ (string s){
  return s+"\n";
}
int main(){
  string text = "text";
  cout << ++text; 
}

but it turns out to overload only the prefix form ++.

I tried to google how to overload the postfix form but found only options using classes. It turned out something like this:

the code

class S{
  public:
   string s;
 
   S(string _s){
        s = _s;
   }

   S operator ++ (int hz){
        s += "\n";
        return *this;
   }
 
};

int main()
{
    S n("text");
    n++;
    cout << n.s ;  
}

In this case, it worked, but is there really no option without using classes (well, at least similar to my first option for the prefix form)?

Answer 1

string operator ++ (string s, int){
return s+"\n";
}
