This might sound like a really dumb question, bout how do you create a banner in an object orientated C++ program. I know with procedural base you can use a void function and call it in several places.
Is there a specific way to do do it in OOP style or will a void function do?
For creation of banner/ticker you do not necessarily need OO concepts/design.
If you want to use OO design, you can still have a method/class function which returns void and you can call that repeatedly too.
void functions and calling them repeatedly has nothing to do with C++ or OO as well.
