Question

Write an expression that executes the loop while the user enters a number greater than or equal to 0.

Note: These activities may test code with different test values. This activity will perform three tests, with userNum initially 9 and user input of 5, 2, -1, then with userNum initially 0 and user input of -17, then with userNum initially -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 "Program end never reached." The system doesn't print the test case that caused the reported message.


#include

using namespace std;


int main() {

int userNum;


userNum = 9;


while (/* Your solution goes here */) {

cout << "Body" << endl;

cin >> userNum;

}

cout << "Done." << endl;


return 0;

}

Answer 1

while (userNum >=0) {...}

Step-by-step explanation:

In a while loop, the loop is executed until the condition is false.

Since the loop will execute while the user enters a number greater than or equal to 0 (and that number is declared as userNum), we need to check if userNum is greater than or equal to 0.
