problem with ofstream?

[larry burns]

The code I have a problem with has been shortened so that only the relevant part is in this message. I have a problem with this code in that the value for height[a][b] vanishes from 0 to 1, from certain values of a and b, as a and b increase in the loop just under the message 'check heigh BEFORE 1st sweep'. So for example, if I have height[10][11]=1, height[15][19]=1, and height[35][12]=1, first height[10][11]=0, then height[15][19]=0 and lastly height[35][12]=0. This makes no sense as none of the conditions of

(height[a][b]=height[a+1][b]) || (height[a][b]=height[a-1][b]) || (height[a][b]=height[a][b+1]) || (height[a][b]=height[a][b-1])

are satisfied, otherwise I would get one of the messages, such as 'WORKS NOW'. Thus, the value of the heights shouldnt change at all, let alone decrease one at a time.
