Which of the following is NOT a valid function prototype? int sum(); void sum();

Q: Which of the following is NOT a valid function prototype? int sum(); void sum();

1.d) int (int sum); is not a valid function prototype because there is no function name 2. a) 2.5 is the answer. Because first a= a+b assigns 5.0 to a, then a/b gives 2.5 3. b) An infinite loop is the answer because c is initialized to 0 , but then in while loop it should be incremented or decrement for the break condition. Since there is no break condition in while loop. It results in infinite loop.
