Sudoku C Programming Code
So, I'm working on a project for my Intro to Software Development course; it's a sudoku puzzle program. So far, I've encountered two big bugs:
1.) When I wrote the code in Visual C++, the display worked fine(it showed up on the
screen as a normal puzzle), but when I copied it over to linux, it displays an
entire line of the input file where only a single digit should go..Can anybody
help me out with that?
2.) At the main menu, after selecting 'e' to edit a square, it tells me that the input
coordinate is not valid. I'm not sure where the problem is there, either
Besides those two major bugs, it appears that everything else is working just fine for the time being. I'd very much appreciate any help that anyone can offer! Thanks a bunch!
(I have yet to develop the algorithms for solving the puzzle, so the last few function definitions are left empty intentionally)

Well I can't repeat the first error. the board looks fine.
The problem with the second error is a simple mistake, so no problem. You wrote this
You input the value into the THIRD coordinate of the char array. There is NO boundary
checking and there is obviously for any input a buffer overflow.
Your conditional test for coordinate[0] and coordinate[1] looks wrong.
Test that with '11' 'AA' entries and I think you will quickly find the problem.
Finally: If I get this to mark, I would be deducting serious marks for the excessive comments. Do you really really need to write the functions in peudo-code and then write the same function? Please unless you absolutely HAVE to have such a pointless comment, write a comment that says what the function is going to do e.g.
The code and the pseudo code are nearly the same, it doesn't help to say i++; // add one to i .

The principle is don't repeat code, and don't repeat code in the comments.
/how-to-load-downloaded-presets-into-serum.html. Obviously this is broken by every C++ book because they are trying to teach what the code means, but you know what the code means. Comment should be for the why and what, not how. e.g. Why do I want an to smooth this data, and that I am using a quadratic summation smoothing, but the code tells me that I am looping over all the points in the data, so no comment is necessary.
Sorry about the rant, had a bad code review today, with a junior dev. who has more than enough ability to have known better by now!
