One of the things which attracted my attention was that there are often newbies asking how to create a password program in C/C++, often they don't succeed, well here's my response, you can use it for any purpose you want, one thing you'll have to keep in mind is that this code will only work on compilers which support conio.h, I know that it's actually a bad habit to make use of this "library", but most of the newbies which are searching for code like this are always using a compiler which supports it, so I guess that won't be a big problem.
As compiler to compile this code I used MinGW.
(The world's best open source compiler for Windows)
You can get the command line compiler from the site, however if you're new to
C/C++ then I would rather suggest you to go and get an IDE featuring the MinGW compiler: Code::Blocks is a very good one, also often used is the Dev-C++ IDE, but there's on major disadvantage of Dev-C++: The source code editor of the IDE isn't being updated anymore (however you can still use it with the newest MinGW compiler, that would be no problem)
