CHALLENGE ACTIVITY 4.2.3: Basic while loop expression Write a while loop that prints userNum divided by 4 (integer division) until reaching 2. Follow each number by a space. Example output for userNum 160 40 102 Note: These activities may test code with different test values. This activity will perform four tests, with userNum 160, then with userNum- 8, then with userNum 0, then with userNum -1. See "How to Use zyBooks". Also note: If the submitted code has an infinite loop, the system will stop running the code after a few seconds, and report Programend never reached. The system doesn't print the test case that caused the reported message 1 #include 2 using namespace std; 1 test passed 4 int mainO 5 int userNum All tests passed cin userNum 9/* Your solution goes here */ 10 cout
