I Want To Learn To Program

Recommended Posts

Verran, each person learns at different rates and in different ways. I for example can't learn any algorithms or something without seeing the cold hard code with a few comments.

 

However, I respect your opinion, and I thank you for staying mature throughout the debate despite my posts.

 

EDIT: Markie, you may be right... the only debugging I've done is with Ollydbg32.exe and my Haaaandie Daaandie... Notebook- I mean Win32 System Kernel Interrupt List!
