Then they have to passed by reference.

Are the returned values different from the ones you are passing in?

Thanks for your reply Richard.

What does that mean?

if we have string as return type then this is specific to string only.
But in real environment, we no need to specific a particular data type.

That really does not explain what this function is trying to do. Why not show the actual function definition and explain in detail what you are trying to achieve?

What's wrong with

C++

ENUM func(std::string name);

?
If you really need to return a value then return it.

As an alternative you could pass an item by reference (see, for instance C++ Functions - Pass By Reference[^])

Another, rather ugly, alternative is changing the value of a global variable.
