Count number of word ( C )

Word in my definition is sequence of non-space character.
Count number of word in sentence was an easy task if you already know the trick.

Example:

My name is Timo ==> counted as four word
I like to solve problems ==> counted as five word


So to create a computer program that count number of word, we can count based on how many space that separate the word (trailing space will be counted once).

int count(char sentence[]) {
  int i;
  int ret = 0;
  int x = 0;
  for(i=0;sentence[i];i++)
  {
      if(sentence[i]!=' ')
      {
          x = 1;
      }
      else
      {
          ret += x;
          x = 0;
      }
  }
  return ret + x;
}

Hope this tutorial will be useful :D.
