C++ using private variable in public function

spudgunner · 02-06-2011, 01:53 PM

I have a class in which a have declared a private variable "time". In one of the public functions, I am returning the value of "time" (either directly by using "return time;" or by something similar to "x=time; return x;" but I keep getting a compiling error saying that "time" is not declared in this scope.

Any suggestions?

How about publishing full code ?

You must be defining the function outside of the class definition. If you had class my_class { void function(); }; make sure that you define void my_class::function() and not just void function().

Hi -

Ta0kira is quite probably correct. It's not "private" that's giving you problems - it's that, wherever you declared it, it's not *visible* where you're *using* it.
