Program p1;
var a,b,c,d : integer; {i presume you give integer numbers for the values of a, b, c }
     x1, x2 : real;

write('a='); readln(a);
write('b='); readln(b);
write('c=');readln(c);
d:=b*b - 4*a*c
if a=0 then x1=x2= - c/b

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);

To create a public key signature, you would use the ______ key.
olya-2409 [2.1K]

Answer:

To create a public key signature, you would use the <u>_private_</u> key.

Explanation:

To create a public key signature, a  private key is essential to enable authorization.

A private key uses one key to make data unreadable by intruders and for the data to be accessed the same key would be needed to do so.

The login details and some important credentials to access user data contains both the user's public key data and private key data. Both private key and public key are two keys that work together to accomplish security goals.

The public key uses different keys to make data readable and unreadable.

The public key is important to verify authorization to access encrypted data by making sure the access authorization came from someone who has the private key. In other words, it's a system put in place to cross-check the holder of the private key by providing the public key of the encrypted data that needed to be accessed. Though, it depends on the key used to encrypt the data as data encrypted with a public key would require a private key for the data to be readable.
