I have no prior knowledge with C++, and I got a few books on it. What I know is that I want to write my code in a file with the .cpp extension.

However, I'm seeing a lot of other extensions in the sample projects I get online.

Examples:

.h
.ncb
.sln
.suo
.vcproj
.aps
.rc

What do they all mean? Do I have to be concerned with them? I hope you guys can help me out, thanks!

They are files you don't have to deal with generally. They are created and used by the compiler. The only extension you need to know about really is the .h file. This is a header file to define stuff in multiple .cpp files. You will use them a lot.

Of the rest in your list
.ncb I've seen but never looked into what it was
.rc defines resources the compiler will put into your executable, like icons
The rest I have no clue. .vcproj by it's name may be some kind of project information for Microsoft's Visual C/C++.
