    You will need to remove the newline that comes along in fgets().

    You'll need a counter variable to keep track of how many times you've gone through the loop. Initialize it to 0 outside the loop and then increment it each time you go through the loop. You can alter the conditional part of the loop to include a check of this value (such that it will exit said loop once the count is 3) or you can put a check inside the loop after the increment step which calls break to exit the loop.
