C++ Question Valid use of "cout"?

[eveningsky339]

Hi everyone. I'm working on a simple calculator program for Orbiter that runs through the Magic Black Box. I feel as though I may be doing something wrong... Can cin and cout be used in a class definition, or must they be confined to the main() function?

For example...

//random.h

Class Random
{

RandomFunction(double a, double b);

}

//random.cpp

RandomFunction(double a, double b)
{

[COLOR=Blue]cout << "Enter a variable: \n";
cin >> a;[/COLOR]

}

The part in blue is what concerns me.

No, you can use cin and cout anywhere in an application that you like (as long as it's a command line app)

try:

std::cout << "blabla";

"std" might be needed if the class file doesn't declare to use the std namespace.

Okay, that's what I needed to know.

try:

std::cout << "blabla";

No worries, I declared std namespace. However, I'll keep this tidbit of info in mind for future reference. :tiphat:

Using it the way you are, though, I have to think that maybe your overall conceptual design isn't the best-thought-out.
