A variable like userNum can store a value like an integer. Extend the given program to print userNum values as indicated.(1) Out

dimulka [17.4K]

Answer:

The program in Java is as follows:

import java.util.*;

public class Main{

public static void main(String[] args) {

int userNum;

Scanner input = new Scanner(System.in);

System.out.print("Enter integer: ");

userNum = input.nextInt();

System.out.println("You entered "+userNum);

System.out.println(userNum+" squared is "+(userNum*userNum));

System.out.println(userNum+" cubed is "+(userNum*userNum*userNum));

int userNum2;

System.out.print("Enter another integer: ");

userNum2 = input.nextInt();

int sum= userNum + userNum2; int product = userNum2 * userNum;

System.out.println(userNum+" + "+userNum2+" = "+sum);

System.out.println(userNum+" * "+userNum2+" = "+product); } }

Explanation:

This declares userNum

int userNum;

Scanner input = new Scanner(System.in);

This prompts the user for input

System.out.print("Enter integer: ");

This gets user input from the user

userNum = input.nextInt();

Number (1) is implemented here

System.out.println("You entered "+userNum);

Number (2) is implemented here

System.out.println(userNum+" squared is "+(userNum*userNum));

System.out.println(userNum+" cubed is "+(userNum*userNum*userNum));

This declares another variable userNum2

int userNum2;

This prompts the user for another input

System.out.print("Enter another integer: ");

This gets user input from the user

userNum2 = input.nextInt();

This calculates the sum and the product

int sum= userNum + userNum2; int product = userNum2 * userNum;

Number (3) is implemented here

System.out.println(userNum+" + "+userNum2+" = "+sum);

System.out.println(userNum+" * "+userNum2+" = "+product);

Consider the following definition of a recursive method. public static int mystery(int[] list, int first, int last) { if (first

ozzi

Answer:

c. 27

Explanation:

In recursion method, a method calls itself until a condition becomes true and returned back. In mystery(), at first time, first is 0 and last is 4. Condition is checked and 0!=4 so else part is executed in which again mystery is called with first as 1 and last 4. This will go again and again until first=4.
When first=4 it is also equal to last so if part is executed and alpha[4] is returned which is 9, now it comes alpha[3] +9 which is 8+9 =17 .
It is returning values to its previous calls that is why it will reduce to alpha[0]+alpha[1]+alpha[2]+17 which is nothing but sum of all elements of a alpha
Then, 1+4+5+8+9=27.

Answer:

The statement to this question is "cout << fraction;".

Explanation:

In the given question it is declared, that a floating-point variable "fraction" is defined, which holds some value. To print this variable value in C++ program we use the print function, which is "cout". This function also used to print messages and values, in this question the print function uses the float variable "fraction", which prints variable value.
