Function is not however the same as operating overloading - which is a different beast entirely.
Not quite, at least not in C based languages. You can't overload by return type, only by function signatures which does not include the return type.
It can be simulated sort of in both C and C++. It probably can in C# too. The question is why would you want to. That's probably indicative of a design fault.
Can you think of a groovy way to do this?
Code:
ReturnType FuncThatCanReturnIntDoubleOrString(void);
There's at least one way in C and 3 ways in C++ this can be accomplished. Can't say for C#. I'm a novice in .net world, never used it.
