Question

I’m getting an error on the second while loop “invalid pointer operation” i thinking its because of the len but i need it to be a pointer so i can address this back. Any suggestions on how to fix this error?

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

  /*POINT TO THE FIRST CHAR*/
  while (string[walker] == ' ' || string[walker] == '\0')
   ++walker;


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

 return (string[walker]);

Deference it:

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

but first make sure it is initialized…

Also, you need to return the pointer to the word, not the char at this address, so write:

return (&string[walker]);

instead of

return (string[walker]);
