What is one potential problem with the following loop? system. out. print("enter integers. enter -1 to exit."); system. out. println(" count of integers entered will be returned."); int n=0; int c=0; while (n ! = -1) { n = scan. nextint(); c++; } system. out. println(c);

The answer to this question can be given as  

The potential problem with the loop is it's counts when the user enters -1 from the keyboard, so the count will too many.

Explanation:

In the program there some line is missing. So the right program of the  question can be given as:  

import java.util.*;     //import package for take input from user.

public class Main     //define main class.

{

public static void main(String[] args)//define main function

{

Scanner scan=new Scanner(System.in);          //creating object.

//print values.

System.out.print("Enter integers. Enter -1 to exit.");

System.out.println(" Count of integers entered will be returned.");  

 int n=0,c=0;           //declaring integer variable.

  while (n != -1)             //loop

   {

       n = scan.nextInt();               //take input by user and hold on variable n.  

       c++;

   }

 System.out.println(c);               //print value.

}

}

output:

Enter integers. Enter -1 to exit. Count of integers entered will be returned.

-1
