Kindergarten Counting Game

Everybody sit down in a circle. Ok. Listen to me carefully.
``Woooooo, you scwewy wabbit!''
Now, could someone tell me how many words I just said?

Input and Output

Input to your program will consist of a series of lines, each line containing multiple words (at least one). A ``word'' is defined as a consecutive sequence of letters (upper and/or lower case).
Your program should output a word count for each line of input. Each word count should be printed on a separate line.

int main(){ 
  char S[SIZE], CH[NUM], c;
  int s, F, C;
  for(s = 0; s < NUM; s++)
  CH[s] = s > 64 && s < 91 || s > 96 && s < 123; 
   
  while(gets(S) != NULL){
     F = C = s = 0;
     while((c = S[s++]) != '\0'){
        if(CH[c])
           F = 1;
        else if(F){
           C++;
           F = 0;
        }
