Learning C and just wrote a function to reverse chars in a char array (ex. "Hello" -> "olleH") but the array did not change.

It took me way to long to realize: I forgot to divide the length variable by two. So it reversed the array back everytime...

    What were you dividing it by?

    If you try to reverse strings like “tacocat” or “radar” it will always work.

    @brtln just curious. Why do you have to divide at all?

    @asgs @brtln is probably doing something like:
    int len = sizeof(array) / sizeof(array[0]);
    len -= 1; // turns count into “max index”
    for (; len <= 0; len--)
    {
    // do stuff at the end and work forward
    }

    But that is going way back for me....
