scanf("%c", &yes_or_no);  
while ((yes_or_no != 'Y') && (yes_or_no != 'N'))

Well you use = where you should be using == in a whole lot of places.

And look backwards from the error line to find a line without a semi-colon.

Then look forward, to see a whole lot of lines without ;

Not to mention all the for(...) statements with only a single expression (and no semicolons) inside the parentheses...

Well, I wasn't sure how if statements worked and for statements seemed the same so I kinda used those o.O

Am new to C so I don't know all the different things like that yet :P
