This expression does not work: "int vertClassification[numOfVerts]". The compiler says its expecting a const expression. numOfVerts is an int variable. Why cant I create an array by not using a const for the size? Or can I? Thanks in advance.

Well, that was a waste of 2 minutes of my life. Now I have to code faster to get 'em back...

You have to create it dynamicly:
int* vertClassification = new int[numOfVerts];

What''s really funny is when you define a constant and it tells you it wants a constant value. Hehe.
