my version of your factorial is this: int s, factorial = 1; std::cout << "Enter a positive integer: "; while ( std::cin >> s && s < 0 ) std::cout << "Enter positive integers only: "; for ( int i = 2; i <= s; ++i ) factorial *= i; …

I'll write a paper to the committee one day!! > I LOVE your C++ for Dummies book I can't believe I read this!! Please, don't say something like this again!

I'm waiting for someone write the matrix multiplication algotithm using C++11 std::future's! But Good Snippet, though! :D (y)

I hope you are not waiting for us to do your job, and that you actually have something done about the problem!

a piece of advice: try to work the digits separately.. and listen to the hint above!

The Boost guys made a tutorial teaching how to install it... http://www.boost.org/doc/libs/release/more/getting_started/index.html check it out!

Since usually the main constraint in C++ is performance, your code is wasting a lot of resources! Try to improve it! Get rid of unused variables and unecessary constants; declare only what you need and where you need. Try to avoid global declarations; Optimize you control structures: consider using 'switch' …

for gcc on windows, this one is better than MinGW, because is constantly updated with the latest release: [Win32](ftp://ftp.equation.com/gcc/gcc-4.7.2-32.exe) [Win64](ftp://ftp.equation.com/gcc/gcc-4.7.2-64.exe) On linux, I used a tutorial a few days ago for ubuntu: http://solarianprogrammer.com/2012/04/13/building-gcc-4-7-on-ubuntu-12-04/

hmm.. improve your grammar on next question! ;) It's more easy to do it in Java than C++, since Java has a API with graphics and sockets.. But if you are really excited ( I really hope you are!!! ), I suggest you look to use [Asio Boost Library](http://www.boost.org/doc/libs/1_51_0/doc/html/boost_asio.html), and …

You're asking in the wrong area!! You might wanna google for "Microsoft Visual C++ Redistributable"!

Plz.. use some space and identation style.. code like this is not fear with people that may help you!!

> I want to develop some soft that will give to the system and apps like Skype data in format they waiting it and take data from camera with its dll-functions so you want to develop the driver itself, right?

the srand() must be putted into your main() function, so it can seed correctly.. there is no need to change nothing else.. just put it on main() and test it!

I suggest you to study the Windows API to learn more about this... look for some tutorials about the windows.h library!

I suggest you study more, because this code is far more than messy! 1- You should follow a indentation style, and use spaces and tabs correctly; 2- Why use the ctime library if the seed number will be inserted by the user? 3- And why use the cmath library? 4- …
