Question

C - Language

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 user input of 9, 5, 2, -1, then with user input of 0, -17, then with user input of -1.

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;

   scanf("%d", &userNum);

   while (/* Your solution goes here */) {
      printf("Body\n");
      scanf("%d", &userNum);
   }
   printf("Done.\n");

   return 0;
}

Answer 1

There should be:-

while (userNum>=0)

Screenshots:-

Sample outputs:-

Here "Body" is printed three times because while loop is executed three times as given input contains three number which is greater or equals to 0.
