Question 4: Implement a function: void printDivisors (int num) This function is given a positive integer num, and prints all of num's divisors in an ascending order, separated by a space. For Example, if we call printDivisors (100), the expected output is: 1 2 4510 20 25 50 100 a. mplementation requirement: Pay attention to the running time of your function. An efficient implementation would run in (Vum b. Use the function above when implementing a program that reads from the user a positive integer (22), and prints all it's divisors. Your program should interact with the user exactly as it shows in the following example: Please enter a positive integer >= 2: 100 1 24510 20 25 50 100
