[Courses] [C] Lesson 8 answer on word counter

[Morgon Kanter]

This thing segfaulted until I realized that i was uninitialized before use. 
The C compiler doesn't catch that like the Java one does =)

#include <stdio.h>
int words(char string[]) {
 int i = 0;
 int returnvalue = 0;
 
 while(1) {
  
  if((i == 0) && string[i] == '\0')) break;
  
  if ((string[i] == '\0') || (string[i] == ' ')) {
   returnvalue++;
   i++;
  }
  else i++;
 }
return returnvalue;
}

main() {
 char line[80];
 int words_in_line;
 printf("Please enter a string: ");
 fgets(line, sizeof(line), stdin);

 words_in_line = words(line);
 printf("%d\n", words_in_line);
}
