Overloading by return type

by

No there isn’t. You can’t overload methods based on return type.

Overload resolution takes into account the function signature. A function signature is made up of:

  • function name
  • cv-qualifiers
  • parameter types

And here’s the quote:

1.3.11 signature

the information about a function that participates in overload
resolution (13.3): its parameter-type-list (8.3.5) and, if the
function is a class member, the cv-qualifiers (if any) on the function
itself and the class in which the member function is declared. […]

Options:

1) change the method name:

class My {
public:
    int getInt(int);
    char getChar(int);
};

2) out parameter:

class My {
public:
    void get(int, int&);
    void get(int, char&);
}

3) templates… overkill in this case.
