My c++ code (use a reset flag to deal with possible spaces at the end of string )

  • 2
    class Solution {
        int lengthOfLastWord(const char *s) {
            int res= 0;
            bool reset = true; // reset flag to trigger the reset of res at the beginning of each new word 
                if(*(s++)== ' ')
                {reset = true;} // if space, set the reset flag
                    res = reset?1:(res+1); // if reset is set, which means the current one is the first char of a new word, then set res to 1, otherwise just increase res.
                    reset = false;
            return res;
