    No, it is exactly your problem. Whoever guided you on your current path wasted your time; you're way off course.

    I took a little hiatus. Probably will take a longer one.

    Better? Does it have to be better? It was supposed to be more in-depth.

    It does not. Slack space sanitizers scrub only the unused parts of the disk, so that any deleted information is really gone.

    For example, when you edit a file, most programs actually write the...

    Ducol, files are allocated in blocks. If you have a very small file, say containing just text "Hello, world!", it would still occupy a full block in storage. If the file is larger than one block,...

    When you don't have access to snprintf() and other string functions, and you wish to build a fixed-size string, you may find that it is easiest to build the string from right to left.

    For example,...

    Ha ha. But no, I deem OSes that provide C libraries that by default insist on mangling the contents of the files non-sane.

    Lots. conio.h. _getch();. scanf_s() instead of scanf(), not checking its return value, and specifying an integer rather than a pointer to a integer to store the result to. You check the input number,...

    I agree with Laserlight. I shall just expand a bit on that, if I may.

    Yes, it is definitely solvable using basics.

    What on earth do you need to do that for?

    You can extend algorism's example so that you can refer to each function using its name, for example

    Are you sure you have empty lines, and not just odd-ish newlines? Maybe CR LF?

    Other than that, it looks like you have one value per line:

    I'd just pick a nonconflicting set of control keys, myself.
    I've always preferred the cursor keys over WASD, anyway.

    If you do have to use those conflicting keys, then the setxkbmap -print option...

    Do the keys actually conflict? It does not look like they do, to me.

    So, you could simply accept both W and Z for "up", and both A and Q for left (and S for down and D for right).
