10443 - Rock, Scissors, Paper

For each string you're only allocating c characters. You need one more for the null terminator.

You also don't free the memory you malloc, so there's a leak.

I'd suggest using a static two dimensional array insead.

Thank you, you are a nice guy
but could you explain this problem for me...
i can't realize it completely...
and my code got wrong answer again...

This problem is one of the most straightforward ones I have seen, so if you are struggling then you are probably doing something wrong. In that case see if the following hints help:

(1) As someone mentioned before, it's probably easier to figure out how a given cell will change based on its neighboring cells than to figure out the opposite. More explicitly, if the current cell is Scissors, it will be a Rock only if one of its neighbors is a Rock.

(2) Like many other problems, if you are storing data for a r-by-c grid, you might want to define char [r+2][c+2] instead of char [r][c] and store the data in the middle so that you don't have to do all the boundary checking. I find this quite helpful, especially for all those problems involving chessboards.

(3) Really can't think of any other tip. Just make sure you output a blank line BETWEEN cases.
