Complete Question:
Write statements that output variable numComputers as follows. End with a newline. There are 10 computers.
#include <iostream>
using namespace std;
int main()
{
int numComputers;
cin >> numComputers; // Program will be tested with values: 10.
...
return 0;
}
Answer:
cout << "There are ";
cout << numComputers;
cout << " computers." << "\n";
Explanation:
Using three cout statements the string "There are 10 computers." is printed out, notice that the variable numComputers is entered by the user when the program is run. Another way of concatenating an integer variable and string for printout is by the use of the + (plus) operator.

Answer:
import java.util.Scanner;
public class num6{
static int getTestScores(){
System.out.println("Enter the Score");
Scanner in = new Scanner(System.in);
int score = in.nextInt();
return score;
}
static double calcAverage(int score1, int score2, int score3){
return (score1+score2+score3)/3;
}
static void displayAverage(double ave){
System.out.println("The Average is "+ave);
}
public static void main(String[] args) {
int num1 = getTestScores();
int num2 = getTestScores();
int num3 = getTestScores();
//Calling Calculate Average
double average = calcAverage(num1,num2,num3);
//Calling displayAverage
displayAverage(average);
}
}
Explanation:
- Using Java programming Language
- Create the four methods
- getTestScores() Uses the Scanner Class to receive an in variable and return it
- calcAverage() accepts three ints as parameter calculates their average and return it
- displayAverage() Accepts a double and prints it out with a concatenated string as message
- In the Main Method, getTestScores is called three times to obtain three numbers from the user
- calAverage is called and handed the three numbers
- printAverage is called to output the calculated average
