Program won't crash when it should

(GCC C)
I ran a pointer over each member of an integer array, storing one character of input in each cell.

The program seems to consistently crash when I try to store X+3 or more characters, where X is the size of the array, but if I do not exceed X+2 it will not crash.

Why does it crashes exactly at the point it does, but not for X+1 or X+2?

>>92

So the program is not correct. Lol.

You're simply intelectually impaired to go anywhere further this  point. And stubborn as a spoiled girlie.

Just fuck off. Stop wasting everyone's time and go back to Wal Mart.
