Hi,
your question is hard to answer, because there is so much about software-development and C++ to read and to learn, that it is hard for me to tell you one good location to find everything.

The first advice I can give you is to look which compiler you are using. For example: If you use Borland C++ Builder, you should go to www.borland.com directly and look at the developer-comunity-sites. Nearly each compiler-product has it's own developer-comunity on the website of the company created the compiler.

You will find lots of sample-codes on this sites. Now it's your turn to decide what kind of programming you want to do. Do you want to do client-server-apps (like me), do you want to develop graphix-applications, games etc....

It is impossible to learn all about developing, without setting a focus on something you want to realize.

Ok, there is another I recommend: Go to www.programmersheaven.com. It is a treasure-chest of really good free sourcecode not only in C++. You can find allmost everything there, from cryptographics to game-development. But you must know what you ae searching for, or you probably get lost in all that information.

another advice is to go to google or another search-engine and type in something like that:

client server programming c++ tutorial sourcecode

There'll be a lot of crap you find by this, but if you are patient, you'll find exactly what you need. By the way, I found www.codeguru.com the same way ;o)

Ok, I hope I could help you a little bit. Feel free to send me an e-mail, if you have any questions.
