Consider the execution of the following code fragment:

int foo(char const array[]) {
  int i, val;
  for (i = val = 0; array[i]; ++i) {
    val = (array[i] == ' ') ? val+1 : val;
  }
  return val;
}
fputs("Enter a sentence: ", stdout);
char str[256];
fgets(str, 256, stdin);
printf("%i", foo(str));

If the user enters the text today is a good day [followed by the keyboard button] in response to the program's prompt, write the exact text printed to the standard output stream by the code fragment's final statement.
