One way that computer networks help to protect data is by backing up the data.

Computer networks are normally formatted to automatically back up all of the data that is stored on them. This protects the data in case of any type of computer system failure.

Write a program that prompts the user to enter in a postive number. Only accept positive numbers - if the user supplies a negati

marusya05 [52]

Answer:

The c++ program to check prime numbers is shown below.

#include <iostream>

using namespace std;

int main() {

int num, prime=0;

{

cout<<"Enter a positive number."<<endl;

cin>>num;

if(num<1)

{

cout<<"Invalid number. Enter a positive number"<<endl;

cin>>num;

}

}while(num<1);

if(num==1 || num==2 || num==3)

cout<<num<<" is a prime number."<<endl;

else if(num%2 == 0)

cout<<num<<" is not a prime number."<<endl;

else

{

for(int k=3; k<num/2; k++)

{

if(num%k == 0)

prime++;

}

if(prime>1)

cout<<num<<" is not a prime number."<<endl;

else

cout<<num<<" is a prime number."<<endl;

}

OUTPUT

Enter a positive number.

-7

Invalid number. Enter a positive number

Enter a positive number.

79 is a prime number.

Explanation:

The user input is validated for positivity. A do while loop along with an if statement is implemented for verification.

{

cout<<"Enter a positive number."<<endl;

cin>>num;

if(num<1)

{

cout<<"Invalid number. Enter a positive number"<<endl;

cin>>num;

}

}while(num<1);

The test for prime number is done by using multiple if else statements.

If user inputs 1, 2, or 3, message is displayed.

Else If user inputs an even number, message is displayed for not prime. This is done by taking modulo of the number upon division by 2.

Else if user inputs neither an even number nor a number less than 3, the modulus of the number is taken with divisors beginning from 3 up to half of the input number.

For this, an integer variable prime is initialized to 0. A number can be completely divisible by itself or by its factors.

If the number is divisible by any of the divisors, value of variable prime is increased by 1. If value of prime is greater than 1, this means that the user input is divisible by more than one divisor. Hence, the given number is not a prime number.

Write, compile, and test the MovieQuoteInfo class so that it displays your favorite movie quote, the movie it comes from, the ch

Irina18 [472]

Using the knowledge of computational language in JAVA it is possible to write a code that removes your favorite phrase from the movie. It consists of two classes in which one is driver code to test the MovieQuoteInfo class.

<h3>Writing code in JAVA:</h3>

public class MovieQuoteInfo { //definition of MovieQuoteInfo class

//All the instance variables marked as private

private String quote;

private String saidBy;

private String movieName;

private int year;

public MovieQuoteInfo(String quote, String saidBy, String movieName, int year) { //parameterized constructor

super();

this.quote = quote;

this.saidBy = saidBy;

this.movieName = movieName;

this.year = year;

}

//getters and setters

public String getQuote() {

return quote;

}

public void setQuote(String quote) {

this.quote = quote;

}

public String getSaidBy() {

return saidBy;

}

public void setSaidBy(String saidBy) {

this.saidBy = saidBy;

}

public String getMovieName() {

return movieName;

}

public void setMovieName(String movieName) {

this.movieName = movieName;

}

public int getYear() {

return year;

}

public void setYear(int year) {

this.year = year;

}

//overriden toString() to print the formatted data

public String toString() {

String s = quote+",\n";

s+="said by "+this.saidBy+"\n";

s+="in the movie "+this.movieName+"\n";

s+="in "+this.year+".";

return s;

}

}

Driver.java

public class Driver { //driver code to test the MovieQuoteInfo class

public static void main(String[] args) {

MovieQuoteInfo quote1 = new MovieQuoteInfo("Rosebud", "Charles Foster Kane", "Citizen Kane", 1941);//Create an object of MovieQuoteInfo class

System.out.println(quote1); //print its details

}

}
