Thread: How to remove end spaces from string

You can start from the last character of the string
then in the loop
check if it is whitespace
and if condition is true - put there '\0' character and move to the previous character.
if you find a non-whitespace character or get to the beginning of the string - you should exit the loop

Code:

int trim( char *s )
{
    if( s )
    {
        if( !*s || (trim( s + 1 ) && isspace( *s )) )
        {
            *s = '\0';
            return 1;
        }
    }
    return 0;
}

Don't turn it in if you can't explain it.
