title: If statement in my loops are being skipped in C
body: <p>In function verify, I have a loop called "size" which is identical to the 3rd loop in "foodSelect" except that it works differently for some reason. It doesn't prompt me for input first, it goes straight to the if inside of it and asks <code>What size (L - Large, M - Medium, S - Small): Please enter S, M, or L only:</code>. It displays the error first, then prompts me again for input. It's weird.</p>
