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);

In a C++ program, one and two are double variables and input values are 10.5 and 30.6. After the statement cin &gt;&gt; one &gt;
SSSSS [86.1K]

Answer:

variable one stores 10.5 and two stores 30.6

Explanation:

In c++ language, the cout keyword is used to write to the standard output. The input from the user is taken by using the cin keyword.

For the input from the user, a variable need is declared first.

datatype variable_name;

The input can be taken one at a time as shown.

cin >> variable_name;

The input for more than one variable can be taken in a single line as given by the syntax below.

1. First, two variables are declared.

datatype variable_name1, variable_name2;

2. Both input is taken simultaneously as shown.

cin >> variable_name1, variable_name2;

For the given scenario, two double variables are declared as below.

double one, two;

The question mentions input values for the two double variables as 10.5 and 30.6.

3. The given scenario takes both the values as input at the same time, in a single line as shown below.

cin >> one >> two;

4. After this statement, both the values entered by the user are accepted.

The values should be separated by space.

First value is stored in the variable one.

Second value is stored in the variable two.

5. The user enters the values as follows.

10.5 30.6

6. The value 10.5 is stored in variable one.

7. The value 30.6 is stored in variable two.

The c++ program to implement the above is given below.

#include <iostream>

using namespace std;

int main() {

   double one, two;      

   cout << " Enter two decimal values " << endl;

   cin >> one >> two;

   cout << " The input values are " << endl;

   cout << " one : " << one << " \t " << " two : " << two << endl;

   return 0;

}

OUTPUT

Enter two decimal values  

10.5 30.6

The input values are  

one : 10    two : 530.6
