These pages attempt to give an overview of some basic concepts, including the structure of the C++ programming language. You can read through them below, or you can refer back to them from pages in the main tutorial when you feel you don't understand a particular topic or piece of terminology.
Unless you are just starting to program you probably already know everything in this section.
Most people find learning by example easier than working from simple descriptions, so most people will find these pages most useful for reference when looking at examples elsewhere.
These are pages on software design and good programming practices (at least in my opinion).
For C programming go out and get "The C Programming Language" 2nd Ed. (or later editions) by Brian W. Kernighan and Dennis M. Ritchie. It is perhaps not the easiest tutorial for C programming, but it is the ultimate bible of C, and you will keep referring back to it even when you are an experienced programmer.
K&R is particularly appropriate if you already know how to program in another language (even BASIC, for example). However, for programming beginners I have had Teach Yourself C in 21 Days and Teach Yourself C++ in 21 Days, both by Sam's Net publishers, recommended to me. I can't actually say anything myself, since I haven't read them.
For a bible of C++ see The C++ Programming Language 3rd Ed. by Bjarne Stroustrup. That book is probably not good for beginners, but more experienced programmers should benefit from the detailed, if somewhat theoretical approach to C++ programming.
