In the Second while loop the data in string is there i checked "data added" however when i stepin and check what string[walker + *len] it constantly has NUL ('\0') even after len is increment? What is the error here ?!?

char* getWord(char* string, short* len)
{
 size_t walker = 0;

  /*POINT TO THE FIRST CHAR*/
  while (string[walker] == ' ' ||开发者_如何学编程 string[walker] == '\0')
   ++walker;


 while ( string[walker + *len] != ' ' || string[walker + *len] != '\0'  )
   ++(*len);

 return (&string[walker]);

You have a few logic bugs there - it should be something like this:

char* getWord(char* string, short* len)
{
  size_t walker = 0;
  *len = 0; // << initialisation of *len

  /*POINT TO THE FIRST CHAR*/
  while (string[walker] == ' ') // << remove incorrect check for end of string
    ++walker;

  while (string[walker + *len] != ' ' && string[walker + *len] != '\0') // << fix logic for testing for space or end of string
    ++(*len);

  return &string[walker];
}

Are you sure that *len is 0 when you call your function? Don't you need to initialize it? Also, in the second while condition I'd guess that you want to use a && rather than ||.
