Nothing wrong with my english. Lots wrong with your code. I don't care
too much about the undefined behavior, because you managed to write
completely incomprehensible code for a very simple task.

void reverse_string (char* s)
{
int i = 0;
int j = strlen (s) - 1;

while (i < j)
{
char tmp = s [i];
s [i] = s [j];
s [j] = tmp;
++i;
--j;
}
}

works and is easy to understand.
