Above should be

@David,<br />
Could you take a look at your if statement again. If both terms are 0, then the for &nbsp;loop is still performed.

it was supposed to be NOT equal rather than Equal. Qlemo fixed it.

I have a beginner question about c++. How I can avoid that the for loops run when FirstSession and LastSession both are 0. <br />

Currently it will run if FirstSession and LastSession are 0.

Avoid for loop with 0

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.
