How would i licence my c command line program, e.g limited functionality without a serial number?
Depends what licensing means ...
Write the license text into the source code resp. show the license text when installing or starting the program.
If you want prevent users from copying the program, things get complicated, you might need some hardware dongle.
Or just make it GPL and give the source code away ...
Include a EULA (End User License Agreement) in your program which users will have to accept while installing/using your application. You can get lots of sample EULAs in Internet. Replace the Names appropriately. But remember, you are gonna do things at your own risk. Read the EULA well, modify it to suit your needs.

I wrote a program in the C language. Now I want to make the system documentation for that program. And, I would like to state the minimum system requirements that are needed to run my my program.
How do I find out what they are?
Things you can do:
Try running your app on the oldest machines you can find.
Remove a couple memory sticks from your computer
Do you have a define _WIN32_WINNT in your application? If not, the windows SDK you use will define the minimum OS requirement.
You can also try compiling with -D_WIN32_WINNT=xx for an older version to see how far back you can go, based on the Windows API calls you use. windows.h is pretty good at hiding APIs for versions newer than the one you specify with _WIN32_WINNT. Then keep that setting to compile your app to create test and release binaries.
Here's the MS doc on versioning with _WIN32_WINNT: https://msdn.microsoft.com/library/windows/desktop/aa383745
Silly me! I forgot to add that you MUST test on the oldest version you specify in your specs + the one most used by your target users.

I got a project that is already developed, in other words I have an API for some software that coded in C language, but the company haven't the source code, thus my mission is to write the source code for this application. Now I have the executable program and I want to write the source code, regarding to my less experience I'm asking, which is better, to write the source code from the scratch or to use some reverse engineering tool to find out the source code? But notice that reverse engineering tools results with some hard to read files since there are not enough comments!
No reverse-engineering tool will give you a source code (with or without the comments). So you can safely abandon this idea.
It is definitely better (in your case) to write new code from scratch using the existing executable as your black-box reference point.
Make sure to have many test cases that should cover as much of the original functionality as possible and when you are done writing your code run them all to affirm that your code is a reasonable replica of the original.

I'm rather new to C++/CX, and right now have an old C project which I need to port into C++/CX.
The output are flushed into text-file or standard output, but it's not that important right now since I can just take them into the Message Dialog there.
My question is that, do you have any tips for porting this project?
I just tried to copy a C file into CPP but failed to compile.
I mean, do I need to wrap the old functions into some kind of Class structure now?
Thanks in advance!
For the differences between C and C++, a starting point is David Tribble's "C99 vs C++98". Without any more details (original C environment, current C++ environment, some details on exact error messages) it is next to impossible to answer the question.

I am writing a dissertation for university final year.
I want to put a large amount of source code on a DVD for the appendix.
95% of code is written by me, but some code is copy and pasted from samples and taken from forums.
Do I have to label each bit of code that is not mine or something?
What would I write if I don't know who's code it is anymore?
You should definitely cite your source if the source specified you do so. However, if you are taking samples and adapting them to your environment you usually don't have to cite it (as long as it has changed in a significant way).
Usually, I try to include a comment in my code if I just copy and paste something, even if it is free and open to copy. However, this is more of a preference than a specification.
In the end, it is up to the people you got the code from (if they specified a license for the code) and your advisor at the university.

To protect software, you can create a validation system which requires users to provide a valid license number (Often 25 letters or digits) which they have to enter with some personal information. This then gets validated (sometimes aby using a validation server, thus requiring online access) and when valid, the user can use the registered version of an application.
Now, simple question: What kinds of solutions are there which would allow developers to implement such a licensing scheme in an easy way into their applications? I could easily create my own solution but I don't want to re-invent the wheel again...
Ezirez Intellilock has a good solution and API to implement it.
Basicly you created a function of (HW ID, Registration Key) and check if it's right.
Intellilock is just a tool to help you lock the software if the license isn't there.
