write a c++ program with out using arrays a. Implement a function: void printDivisors(int num) This function is given a positive integer num, and prints all of nums divisors in an ascending order, separated by a space. For Example, if we call printDivisors(100), the expected output is: 1 2 4 5 10 20 25 50 100 Implementation requirement: Pay attention to the running time of your function. An efficient implementation would run in . b. Use the function above when implementing a program that reads from the user a positive integer (2), and prints all its divisors. Your program should interact with the user exactly as it shows in the following example: Please enter a positive integer >= 2: 100 1 2 4 5 10 20 25 50 100
