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 <stdio.h> int main(void) { int userNum; userNum = 9; while (userNum>=0) { printf("Body\n"); scanf("%d", &userNum); } printf("Done.\n"); return 0; }
Basic while loop expression.

Note: These activities may test code with different test values. This activity will perform four tests, with userNum = 40, then with userNum = 2, then with userNum = 0, then with userNum = -1. See “How to Use zyBooks”.
