Array Help

Im having a problem with a 2d array ttGrid[2][2]
I init the int array to Zeroes
but if i set the [0][2] index to a value, the value will spill over into the [1][0] index.
so in the below example you can see im setting [0][2] to 9, well both this and [1][0] will have the value 9 now, im at a loss!...
array[2][2] creates a 2x2 array, or 4 elements.
0,0; 0,1; 0,2; 1,0; 1,1; 1,2; 2,0; 2,1; 2,2; 9 elements...
0,0; 0,1; 0,2; 1,0; 1,1; 1,2; 2,0; 2,1; 2,2; 9 elements...

which is what i want, basically a tic tac toe board
but, if i set the index 0,2 to something, 1,0 gets the same value
i see the same behavior with index 1,2 now 2,0 will gets the same value, its like the value is spilling over in memory or something?
if you want 9 elements, make 9 elements.
array[3][3];
And yes, it's similar to a simple buffer overrun, and the source of nearly every virus, worm, and exploit in the past 2 decades.

You only have 4 elements not 9 like in tic-tac-toe.
[2][2] = [0][0],[0][1],[1][0],[1][1]
There is no [0][2] as that would be the third element and therefore instead points to [1][0].
Use ttGrid[3][3]
Edit: Damn it, too slow :(

oh my god my brain is fried....
i completely forgot that the subscript is the actual number of indexes you want, so i was thinking [2] or 0,1,2 in the subscript gives me 3x3
bah, thanks guys sorry for wasting time

Never think of it as wasting anyone's time. You may asked a question 10 other people were too shy to ask, and now they know the answer.
