Problem at functions on dev c++ control

[Ricardo Luiz Barros de Freitas]

Some of my functions are not being shown in the class on the left side of the screen. I don't understand the problem.
I put a file with the screen and program it all.

I dont understand. The program runs without any problems.

When i used at Another program, everything is all right. But I prefer to use DevC++.

What is black box testing?

I instaled New Dec C++ and the problems continue.
