  : O.K. I actually have a found a way to count words in a string... but I couldn't figure out a logic for it.
  :
  : Here's the code
  : [code]
  : #include
  : #include
  :
  : int main(void)
  : {
  : char input01[255] = "This is just a test";
  : char input02[255] = "This is another test";
  : char *p;
  :
  : p = strtok(input01, " ");
  : if (p) printf("%s
  ", p);
  :
  
  : So how do I convert this code so, that it uses a while loop to count how many words in the string are with strtok ???
  :
  
  Use a while loop like this:
  
  p = strok(input01, " ");
  
  while(p) {
  printf("%s
  ", p);
  p = strtok(NULL, " ");
  }

  : p = strtok(NULL, " ");

  You could also use a for loop:
  [code=ffffff]
  for ( p = strtok(input01, " "); p; p = strtok((char *)0, " ") ) {
  puts(p);
  }
  [/code]
  Of course, this is more of a style issue than anything, but the for loop is made for situations just like these.
  
  Note that it is a good idea to cast the NULL macro, or 0 (whichever you prefer for null pointer constants) when using them as a function argument. Check the C FAQ section 5 for more (second link in my sig).
