Question

Write a piece of code that enters a loop and asks the user to input anon-negative number. If the user enters a negative number, the code goes back into the loop and asks the user again to enter a non-negative number. The code keeps going back into the loop until the user enters a non-negative number. Notice that the code enters the loop at least once. This is an application of 1 to N loop.Therefore, use a Do While statement.

Answer 1

#include <stdio.h>

int main {

int num;

do {

printf ("enter a number");

scanf ("%d",&num);

}while (num <0);
