How to undo words one by one in c using pointers and arrays

Hey yes, you guessed it was homework. I am trying to print a string in reverse order with pointers. Only words. So hello world is olleh dlrow. What I do in the code below assigns one pointer (pSentence, which is a string array of several words passed from the main function) to a temporary pointer to a space, then increments it back and prints the character from the temporary pointer to the beginning of the word, then do it again. I’m stuck right now, I don’t know how to mark the beginning of a word and grow only to this. I know that while (pt! = '0') is not a way to do this at all. The tooltip says to save the word in a temporary line (tmpStrg) and use pT to point to it, so maybedo i need to do something using tmpStrg? Any help is greatly appreciated and thank you in advance.

void prtWords(char *pSentence)
{
    char tmpStrg[81], *pT=tmpStrg;
    int length=0;

    while(*pSentence != '\0')
    {
       while(*pSentence != ' ' && *pSentence != '/0')
       {
         *pT=*pSentence;
         pT++;
         pSentence++;
         length++;
       }
       pSentence++;

       while(length >= 0);
       {
         printf("%c", *pT);
         pT--;
         length--;
       }
    }
