Answer:
Explanation:
The following is written in Java. It continues asking the user for inputs until they enter a -1. Then it saves all the values into an array and calculates the number of values entered, the highest, and lowest, and prints all the variables to the screen. The code was tested and the output can be seen in the attached image below.
import java.util.ArrayList;
import java.util.Arrays;
import java.util.Scanner;
class Brainly {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        int count = 0;
        int highest, lowest;
        ArrayList<Integer> myArr = new ArrayList<>();
        while (true) {
            System.out.println("Enter a number [0-10] or -1 to exit");
            int num = in.nextInt();
            if (num != -1) {
                if ((num >= 0) && (num <= 10)) {
                    count+= 1;
                    myArr.add(num);
                } else {
                    System.out.println("Wrong Value");
                }
            } else {
                break;
            }
        }
        if (myArr.size() > 3) {
            highest = myArr.get(0);
            lowest = myArr.get(0);
            for (int x: myArr) {
                if (x > highest) {
                    highest = x;
                }
                if (x < lowest) {
                    lowest = x;
                }
            }
            System.out.println("Number of Elements: " + count);
            System.out.println("Highest: " + highest);
            System.out.println("Lowest : " + lowest);
        } else {
            System.out.println("Number of Elements: " + count);
            System.out.println("No Highest or Lowest Elements");
        }
    }
}
 
        
             
        
        
        
Answer:
A computer is a machine that can be programmed to carry out sequences of arithmetic or logical operations automatically. Modern computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks. A computer system is a "complete" computer that includes the hardware, operating system (main software), and peripheral equipment needed and used for "full" operation. This term may also refer to a group of computers that are linked and function together, such as a computer network or computer cluster

Answer:
The answer to this question is given below in the explanation section. 
Explanation:
The correct answer to this question is initialization. 
When you write a variable in a program,  for example int firstNumber. The integer variable firstNumber is declaring in the program.
when you assign a data value to a variable in a program is referred to as initialization. for example:
firstNumber=10;
You can declare and initialize the variable in one statement such as:
int firstNumber=10;
