(Sieve of Eratosthenes) Modify Fig. 22.40, the Sieve of Eratosthenes, so that, if the number the user inputs into the program is not prime, the program displays the prime factors of the number. Remember that a prime number’s factors are only 1 and the prime number itself. Every nonprime number has a unique prime factorization. For example, the factors of 54 are 2, 3, 3 and 3. When these values

are multiplied together, the result is 54. For the number 54, the prime factors output should be 2 and 3. What will be an ideal response?

Which of the following statements is false?

a) A key feature of functions like printf_s and scanf_s that makes them more secure is that they have runtime pointer constraints that are checked after attempting to use the pointers. b) In a scanf_s, if any of the pointer arguments (including the for-mat-control string) are NULL, the function returns EOF. c) In a printf_s, if the format-control string or any argument that corresponds to a %s is NULL, the function stops outputting data and returns a negative number. d) None of the above.
