Question

In the following code, what values could be read into a number to terminate the while loop? PRINT "Enter a number: READ user input number ← user input WHILE (number < 1 or number > 10) PRINT "Enter another number: " READ user input number ← user input END WHILE

A) Numbers in the range 0 - 9

B) Numbers in the range 1 - 10

C) Numbers greater than 10

D) Numbers less than 1

Answer 1

Solution:

Option B is correct which is Numbers in range 1-10 (including 1 and 10)

Example code in C:

#include <stdio.h>
int main()
{
   int n,an;
   printf("Enter a number:");
   scanf("%d",&n);
   while(n<1 || n>10)
   {
       printf("enter another number:");
       scanf("%d",&n);
   }
}

In output file first line tried range between 0-9 where loop still runs and next one numbers less than 1 and next one numbers greater than 10 and when I give input range between 1-10 (you can try even other numbers like 2,3,4..) then loop terminated.

Thank you, Have a great day:-)
