Everything here is about C++ programming in Windows. Why to program? Professional programmers do it to make a living. Just users just want to be advanced users. And an advanced user is the one who can program.
It's possible to find free or buy ready programs which can do whatever we want. But not everything and as a rule not the way we want it. We don't have control over them, we cannot change programs without being able to program and having its source code.
Programming is needed to master computer, to use all of its resources. In most cases one may need it to perform personal specific tasks, to achieve certain goals which no ready programs can do exactly as we need. And if it is our program we can always modify it to meet all our requirements, to do exactly what we want.
This site is about C++ syntax, semantics, ideas about which C++ compiler is the best, source code etc. Here you can find some tutorials.
Programming under Linux looks more interesting. But there is a problem. Some programs exist only for Windows operating system. Most computer users use Windows operating system. Number of Linux users is growing, but not very fast. Therefore creating programs in C++ for Windows is a great help.
