I know all the basic stuff of C++...
But how can I actually use C/C++ to make programs which can be more than calculators on a windows-console?
For example, the FDISK program...I know its made with C,
but how and where can I learn to program USEFULL things in C/C++? On that low height?
You can't--you've come to landsend. Now, it's time to put away such childish toys and make something of yourself.Quote:

Learn more of the language.
I would disagree with your implication that the only useful things are the low-level stuff.
Anyway. The trick in low-level stuff is usually direct hardware access. Now, let me say first that modern OSs such as WinNT and Linux don't allow direct hardware access. But they might provide alternative ways of doing low-level stuff in a limited way.
Example: I believe fdisk for Linux uses the /dev/hdx devices to directly access the hard disk and modify partition information. The WinNT disk management utility might have a kernel-level part that it can communicate with. The DOS fdisk used interrupts and ports directly.
What way you do it depends in the end on the system you're developing for. System programming is by definition system-specific.
It depends on what you're looking to do. There are several libraries out there that you could use for most things, but it's all in what your goal is.
If you want to get to graphics and other things, you have a few options. You can go with OpenGL or another library or you could just learn Windows programming. Those are hard, so I wouldn't recommend that.
You could also get some libraries for File I/O, networking, and other things. These can be effective but they can be expensive or slow and difficult to use, but you probably could get a good one.
This all depends on what you want to do with your programs. Set a goal and find out how to reach it. Keep trying and you'll probably make your goal.
Hope that helps,

You mention, for example, graphic-libaries...
Well, THEY must have been programmed&coded as well..?
And how do the FDISK program do the actual formatting&partionationg work? Is it assembler?
Graphics libraries have their cores in the operating system and device drivers. Those are usually written in C, with perhaps some assembly mixed in. Like fdisk. I think if you want to do that kind of stuff you should get a big book about computer architecture, both hardware and software.
