1. Write a C++ program that reads a positive integer and prints all of its binary digits (in reverse order). Print the number % 2, then replace the number by number / 2. Keep going until the number is 0. Validate the input. Do not accept a negative integer. Sample run of program: Enter a positive integer: >2 Invalid input! Try again: > 20 Your number in binary in reverse order is: 0 0 1 0 1
