Improved Prompt Program

To complete the program, add one to count as the documentation suggests.

Notice how the three variables value, sum, and count work together. Often in programming, you need to coordinate several variables.

Let us work on improving the grammar in the prompt. We will use nested if-else statements inside the loop body.

    int value;             // data entered by the user
    int sum = 0;           // initialize the sum

    int count = 0;   // number of integers read in

    // get the first value
    System.out.println( "Enter first integer (enter 0 to quit):" );
    value = scan.nextInt();

    while ( value != 0 )    
    {
      //add value to sum
      sum = sum + value;

      //increment the count
      count = count + 1;

      //get the next value from the user
      System.out.println( "Enter the " + (count+1) + "th integer (enter 0 to quit):" );
      value = scan.nextInt();
    }

    System.out.println( "Sum of the "  + count + " integers: " + sum );
  }
}
