Answer:
- import java.util.Arrays;
- import java.util.Scanner;
-
- public class Main {
- public static void main(String[] args) {
- Scanner input = new Scanner(System.in);
- double distances [] = new double[7];
-
- for(int i=0; i < distances.length; i++){
- System.out.print("Input running distance for day " + (i+1) + ": ");
- distances[i] = input.nextDouble();
- }
-
- System.out.println(Arrays.toString(distances));
- }
- }
Explanation:
The solution code is written in Java.
Firstly, create a Scanner object to get user input for running distance (Line 6). Next, declare a distances array and set the array size to 7 because we intend to use this array to hold running distance for 7 days per week.
Next, use the for loop that run for 7 times to repeatedly prompt user to input running distance for each day and store each value to the array distances (Line 9 -12).
At last, display the array to console terminal (Line 14).

The answer is true.
Let's say we are calculating the volume of a grain silo where the the width is a constant, but the height can be changed.
In our code we would calculate the volume using something like:
PI * (WIDTH / 2)^2 * height
The variables in all caps would be named constants. Using them makes the code more readable to other people than if we were to just use their values like:
3.14 * (145.75 / 2)^2 * height
