Following are the C++ program to calculating the average value.
Program Explanation:
- Defining header file.
- Defining the main method.
- Defining three double variable "numStars,averageStars, and totalStars", and one integer variable "numPatrons".
- After declaring a variable, an input method is used that inputs an integer variable.
- In the next step, a while loop is declared that uses an integer variable to the check value between 0 to 4.
- Inside the loop, it adds the integer variable value and uses a conditional statement that checks integer value equal to 0, that hold 0 value into the "averageStars".
- In the else block it calculates the average value and prints its value.
Program:
#include <iostream>//defining header file
#include <string>//defining header file
using namespace std;
int main()//main method
{
double numStars,averageStars,totalStars=0; // defining a double variable
int numPatrons = 0; //defining integer variable
cout << "Enter rating for featured movie: ";//print message
cin >> numStars;//input integer variable
while(numStars >= 0 && numStars<=4)//using while loop that use integer variable to check value in between 0 to 4
{
numPatrons++; // increasing integer variable value
totalStars += numStars; // using totalStars that adds numStars value in it
cout << "Enter rating for featured movie: ";//print message
cin >> numStars;//input double value
}
if(numPatrons == 0)//using if block that check integer value equal to 0
averageStars = 0;//holding value into averageStars
else//else block
averageStars = totalStars/numPatrons;//calculating averageStars value
cout << "Average Star Value: " << averageStars << endl;//print message with averageStars value
return 0;
}

Explanation:
The following program is written in Java and creates three levels with the different set of randomly generated arithmetic problems. As the player goes getting more points they advance every 5 points to the next level.
import java.util.Random;
import java.util.Scanner;
class Main {
private static Random random = new Random();
private static Scanner in = new Scanner(System.in);
static int points = 0;
public static void main(String[] args) {
while (true) {
System.out.println(points);
if (points < 5) {
System.out.println("Starting Level 1");
levelOne();
} else if (points < 10) {
System.out.println("Starting Level 2");
levelTwo();
} else if (points < 15) {
System.out.println("Starting Level 3");
levelThree();
}
}
}
public static boolean levelOne() {
int numberOne = random.nextInt(10);
int numberTwo = random.nextInt((10 - numberOne));
int answer = numberOne + numberTwo;
int count = 0;
while (points < 5 && count < 2) {
System.out.println("What is " + numberOne + " + " + numberTwo + "?: ");
int userChoice = in.nextInt();
if (userChoice == answer) {
points += 1;
levelOne();
} else {
count += 1;
}
}
return false;
}
public static boolean levelTwo() {
int numberOne = random.nextInt(10);
int numberTwo = random.nextInt(10);
int answer = numberOne + numberTwo;
int count = 0;
while (points < 10 && count < 2) {
System.out.println("What is " + numberOne + " + " + numberTwo + "?: ");
int userChoice = in.nextInt();
if (userChoice == answer) {
points += 1;
levelTwo();
} else {
count += 1;
}
}
return false;
}
public static boolean levelThree() {
int numberOne = random.nextInt(10);
int numberTwo = random.nextInt(10);
int answer = numberOne - numberTwo;
int count = 0;
if (answer <= 0) {
levelThree();
}
while (points < 15 && count < 2) {
System.out.println("What is " + numberOne + " - " + numberTwo + "?: ");
int userChoice = in.nextInt();
if (userChoice == answer) {
points += 1;
levelThree();
} else {
count += 1;
}
}
return false;
}
}
