I am a self-taught programmer. I have been studing and using Visual Basic for Applications for some years and made a pretty good living at that. I'd like advance now to C programming. I have selected C# as the most likely language to help me break through into C programming. Years ago I did some work in Borland C. The results were pretty good, but I didn't really implement classes. Evidently I'll need to become proficient with C's class structure and OOP before I'll become anything resembling a C programmer. I am grateful for every reply.
