What makes you think the buffer isn't being overflowed?
}
int main(int argc, char **argv)
{
func("AAAAAAAAAA"); // i have supplied 2 X 5 char to it
Then you're trying to store more data in the array than it has room for,
and you don't provide any safeguards against that, so you're overflowing
that buffer, and the result is that the program exhibits undefined
behaviour - i.e. the rules of C don't tell you what will happen.
