Something within a while loop must eventually cause the condition to become false, or a(n) results.
1. null value
2. infinite loop
3. unexpected exit
4. compiler error
5. none of these

Infinite loop

Explanation:

A while loop terminates when the condition within the loop becomes false else the it will continue to loop for ever and thereby lead to memory overflow.

example : while(i<10)

                      {  print("hello");

                        }

  here if value of i <10 then it will print hello, but if there is no condition it will lead to an infinite loop. example : while();
