Thread: comparing array contents

okay now it ran, but for some reason, the entire loop was completely skipped over. that cannot be since while(1) and the only way to get out of the whole thing is if the if statements inside are true which have break; in them to get out of the loop. i never get asked for the row or column at all. it asks for names and goes to press ESC to exit...

Code:
