For example:

wxString aaa(wxString b) {

}

b is a optional arguement, it can be?

Thank you.

Hi!
When definnig the prototype for that function use a default argument like
wxString somefunc(wxString b = "");
You don't need to repeat defaults in the implementation of the function.

Another way would be to overload the function so that there is
wxString somefunc();
and
wxString somefunc(wxString b);

You could also use an argument list of variable length, going from 0 to n. But I guess you don't want that...

If it was hard to write, it should be hard to read!- Do. Or do not. There is no try!
