    Basically, just check if the 0th (first) letter is equal to the last,
    the 1st (second) equal to the one before last
    ...
    the nth equal to the (last-n)th
    ...
    until you've checked all of them (except maybe a single middle letter for strings with odd length).

    Wasn't that lesson #2 (lesson #1 being the famous "Hello, World!" program)?
    Did you miss the class, maybe ...

    Check the fgets() function. It is a safe way to get strings.
