Please help with this: error expected declaration or statement at end of input

Solved
I've googled this problem and it seems people who had it messed up their curly braces, but I've checked a couple times and couldn't find anything wrong with my code. Maybe someone can spot something I didn't see or maybe it has nothing to do with braces in my case.

I was trying to make a text based minesweeper, the error is in the last function (all the way at the bottom)
It probably has other errors too since I wrote it fast but I'm just concerned with this one since I can't find the other errors until I fix this one

Code:

#define SOLVE 7173
#define ES 5322 //empty space - not part of visible board

You indentation is wrong after this line; I am guessing you are missing a closing

Thanks so much, I thought the problem was in the solvearea function so I kept searching that, I didn't know it could be in other parts of the program.

**~~CommonTater~~** · 04-28-2011

It may be compiler dependent but most often when I see that error on the last line of a file, it's because there is no newline at the end of the file. Going to the bottom of the file and tapping enter a couple of times usually dlears it up... all else being correct, that is/
