Example Code Ch 02-2
import java.util.Scanner;
public class Questions33_34
{
public static void main(String[] args)
{
int x, y, z;
double average;
Scanner scan = new Scanner(System.in);
System.out.println("Enter an integer value");
x = scan.nextInt();
System.out.println("Enter another integer value");
y = scan.nextInt();
System.out.println("Enter a third integer value");
z = scan.nextInt();
average = (x + y + z) / 3;
System.out.println("The result of my calculation
is " + average);
}
}
-Refer to Example Code Ch 02-2. This code computes
A) The correct average of x, y, and z as a double
B) The correct average of x, y, and z as an int
C) The average of x, y, and z as a double but the result may not be accurate
D) The sum of x, y, and z as an int
E) The remainder of the sum of x, y, and z divided by 3

Question

Quizplus · Accepted Answer

The code correctly calculates the average of x, y, and z, but since the variables are integers, the result will be truncated to an integer. To get an accurate average as a double, one or more of the variables should be declared as a double or the calculation should include a conversion to double, such as (x + y + z) / 3.0.
