Hey people!!!
Bit of a simple question for you all but it might solve a few
porblems for me.
basially, i want to know if the '\n' character is put into the buffer
everytime i press enter after a 'scanf' or 'fgets' .etc
And if this is the case do i need to leave two extra characters to
house the resulting '\n' and '\0' characters?

FgetsCode:s Matches a sequence of non-white-space characters; the next pointer must be a pointer to character array that is long enough to hold the input sequence and the terminating null character (’\0’), which is added automatically. The input string stops at white space or at the maximum field width, whichever occurs first.
Code:fgets() reads in at most one less than size characters from stream and stores them into the buffer pointed to by s. Reading stops after an EOF or a newline. If a newline is read, it is stored into the buffer. A ’\0’ is stored after the last character in the buffer.

scanf is finicky with whitespace (it usually acts as an unread delimiter), and fgets stores the newline if possible.
My best code is written with the delete key.
so if the string isnt full up after the input, fgets will put the '\n' but if there is no space it's forgotten?

No, it's left for the next input call (say another fgets) to deal with.
Mostly it's not important if you pick a reasonably large buffer size. If it is, you can always look for the \n and take appropriate action.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
