Question 4 1 pts Consider the following code #include #include int main(void) char buf[ 100], word[ 20], num [ 20]; int course = 0; CODE A return 0 Which of the following replacements for CODE A produce the following output when the program input is "CS 354"? CS 354 1. CODE A is: fgets (buf, sizeof (buf), stdin); sscanf (buf, "%s %d", word , course); printf("%s %d ", word, course); 2. CODE A is: fgets (buf, sizeof (buf), stdin); sscan f (buf, "%s %s", word, num); printf ("%s %s ", word, num); 3. CODE A is: fgets (buf, sizeof (buf), stdin); sscanf ( buf, "%s %d", word, &course); printf("%s %d ", word, course); 4. CODE A is: fgets (buf, sizeof (buf), stdin); sscanf (buf, "%s %s", &word, &num); printf ("%s %s ", word, num); o 4 only O 1 and 3 o 1 only 2 only 2 and3
