Give the output of the following program using the four parameter passing methods(Pass by Value, Pass by Reference, Pass by Value-Result, Pass by Name). Code: int i;int a[3]; void swap(int x, int y){    x = x + y;    y = x - y;    x = x - y;} main(){    i = 1;    a[0] = 2;    a[1] = 1;    a[2] = 0;    swap(i,a[i]);    printf("%d %d %d %d\n", i, a[0], a[1], a[2]);    swap(a[i],a[i]);    printf("%d %d %d\n", a[0], a[1], a[2]);    return 0;}

Identify the errors in the following code. class A { void sum(int x, int y){ System.out.println("Sum of two numbers: " +(x+y)); } void sum(int y, int x){ System.out.println("Sum of three numbers: " +(x+y)); } public static void main(String[] args){ A a = new A(); a.sum(20, 30); } }

Complete the following program to implement the user interface of the preceding exercise. For simplicity, only the units cm, m, and in are supported. Hint: The value of factor1 or factor2 should be the conversion factor from the selected unit to cm. Ex: If the selected unit is in, factor1 is 2.54 because 1 in = 2.54 cm. import java.util.Scanner; public class UnitConverter{   public static void main(String[] args)   {      Scanner in = new Scanner(System.in);      boolean done = false;      double factor1 = 0;      double factor2 = 0;      String unit1 = "";      String unit2 = "";            while (!done)      {         boolean getSecond = true;                  String command = in.next();         System.out.println("From unit (in, cm, m, again, quit): " + command);         if (command.equals("in"))         {            factor1 = 2.54; // Convert to cm             unit1 = command;         }         else if (command.equals("cm"))         {            /* Your code goes here */         }…

Please answer 6 and 7 as they are associated altogether. 6. The FixProgram.java below has some errors.a. Fix the errors so that the program successfully compiles and runs. class FixProgram{ public static void main(String[] args) { System.out.println('Hello World!') }}  7. Change the SampleProgram.java program below.a. So that it displays Programming is fun! Instead of Hello World! class SampleProgram{ public static void main(String[] args) { System.out.println("Hello World!"); }}

JAVA  Question 2: For two integers m and n, their GCD (Greatest Common Divisor) can be computed by a recursive method. Write a recursive method gcd(m,n) to find their Greatest Common Divisor. Method body: If m is 0, the method returns n. If n is 0, the method returns m. If neither is 0, the method can recursively calculate the Greatest Common Divisor with two smaller parameters: One is n, the second one is m mod n (or m % n). The recursive method cannot have loops. Note: although there are other approaches to calculate Greatest Common Divisor, please follow the instructions in this question, otherwise you will not get the credit. main method: Prompt and read in two numbers to find the greatest common divisor. Call the gcd method with the two numbers as its argument. Print the result to the monitor.   Example program run: Enter m: 12 Enter n: 28 GCD(12,28) = 4 And here is what I have so far, package CSCI1302;import java.util.*;public class RecursionDemo {    public static void…

Write factorial1 function in python 3.8 follow the directions provided below, don't need anything else as long as it meets all the requirements below. Function: factorial1 The function implements an iterative factorial. It takes an integer n as argument and returns n! The method needs to be computed interactively (not recursively

(YOU ARE NOT ALLOWED TO USE ARRAYLIST IN THIS PROJECT)Write a Java program to simulate a blackjack game of cards. The computer will play the role of the dealer. The program will randomly generate the cards dealt to the player and dealer during the game. Cards in this game will be represented by numbers 1 to 13 with Ace being represented by a 1. Remember, that face cards (i.e. Jack, Queen, and King) are worth 10 points to a hand while an Ace can be worth 1 or 11 points depending on the user’s choice. The numbered cards are worth their number value to the hand.

Do not use static variables to implement recursive methods.  USING JAVA USING: // P5         public static long computePay(int day) {         } You have been offered a job that pays as follows: On the first day, you are paid 1 cent, on the second day, 2 cents, on the third day, 4 cents and so on. In other words, your pay doubles every day. Write a recursive method computePay that for a given day number computes the pay in cents.    Assume that you accumulate all the money that you are paid. Write a recursive method computeSavings that computes the sum that you have accumulated on a given day. Show the output of computePay and computeSavings for day number 39.

This is the question:  The Huntington High School basketball team has five players named Art, Bob, Cal, Dan, and Eli. Accept the number of points scored by each player in a game and create a bar chart that illustrates the points scored by displaying an asterisk for each point.  This is the code given: import java.util.Scanner; public class BarChart {     public static void main (String[] args) {         Scanner input = new Scanner(System.in);         int artPoints;         int bobPoints;         int calPoints;         int danPoints;         int eliPoints;         System.out.print("Enter points earned by Art >> ");         artPoints = input.nextInt();         System.out.print("Enter points earned by Bob >> ");         bobPoints = input.nextInt();         System.out.print("Enter points earned by Cal >> ");         calPoints = input.nextInt();         System.out.print("Enter points earned by Dan >> ");         danPoints = input.nextInt();…
