Answer:
A
Explanation:
The main output of Project palnning is project plan.
Solution:
It is done by Operating system.
An Operating system is system software that manages computer hardware and software resources and provides common services for computer programs.
Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources.
For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer – from cellular phones and video game consoles to web servers and supercomputers.
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
"add-in" is pretty ambigious but I would go with true for this one.
