Find the end of the string (marked by '\0') and go backwards from there,
moving the '\0' to the left one space if the character there is whitespace.

(Assuming p is a char *, save the original value cause p will not point to
the beginning of the string after this)

while(*p != '\0') p++;
while(isspace(*--p)) *p = '\0';
