Maintenance is an essential task that is often considered to be dull. In information security, penetration testing may be wrongl

y perceived as being a "hacker-like" activity. In fact, when done correctly, ethical hacking is an important part of risk management. Penetration analysts work under very restrictive rules of engagement when testing systems. This week's project is research on the many ways that penetration analysts limit the risk they pose to internal systems.

<u>Explanation:</u>

It is important to bear in mind that a penetration tester (analyst) performs a risk management role of a firm's internal system by attempting to break into an IT system.

Here are the benefits to internal systems;

  • They help detect security loopholes before a cyberattack.
  • They determine how vulnerable a network or computer program is.
  • They advise the IT firm's security teams on how to mitigate vulnerabilities detected.

Write a program that will open the file random.txt and calculate and display the following: A. The number of numbers in the file
Rama09 [41]

Answer:

Here is the C++ program:

#include <iostream>  //to use input output functions

#include <fstream>  //to manipulate files

using namespace std;  //to identify objects like cin cout

int main(){  //start of main function

  ifstream file;   //creates an object of ifstream

   file.open("random.txt"); //open method to open random.txt file using object file of ifstream

       

    int numCount = 0;  //to store the number of all numbers in the file          

    double sum = 0;   //to store the sum of all numbers in the file

    double average = 0.0;   //to store the average of all numbers in the file

    int number ; //stores numbers in a file

                 

        if(!file){   //if file could not be opened

           cout<<"Error opening file!\n";    }   //displays this error message

       

       while(file>>number){   //reads each number from the file till the end of the file and stores into number variable

           numCount++; //adds 1 to the count of numCount each time a number is read from the file          

           sum += number;  }  //adds all the numbers and stores the result in sum variable

           average = sum/numCount;  //divides the computed sum of all numbers by the number of numbers in the file

     

       cout<<"The number of numbers in the file: "<<numCount<<endl;  //displays the number of numbers

       cout<<"The sum of all the numbers in the file: "<<sum<<endl;  //displays the sum of all numbers

       cout<<"The average of all the numbers in the file: "<< average<<endl;  //displays the average of all numbers

       file.close();     }  //closes the file    

   

Explanation:

Since the random.txt is not given to check the working of the above program, random.txt is created and some numbers are added to it:

35

48

21

56

74

93

88

109

150

16

while(file>>number) statement reads each number and stores it into number variable.

At first iteration:

35 is read and stored to number

numCount++;  becomes

numCount = numCount + 1

numCount = 1      

sum += number; this becomes:

sum = sum + number

sum = 0 + 35

sum = 35

At second iteration:

48 is read and stored to number

numCount++;  becomes

numCount = 1+ 1

numCount = 2    

sum += number; this becomes:

sum = sum + number

sum = 35 + 48

sum = 83

So at each iteration a number is read from file, the numCount increments to 1 at each iteration and the number is added to the sum.

At last iteration:

16 is read and stored to number

numCount++;  becomes

numCount = 9 + 1

numCount = 10    

sum += number; this becomes:

sum = sum + number

sum = 674 + 16

sum = 690

Now the loop breaks and the program moves to the statement:

       average = sum/numCount;  this becomes:

       average = 690/10;

       average = 69

So the entire output of the program is:

The number of numbers in the file: 10                                                                                                           The sum of all the numbers in the file: 690                                                                                                     The average of all the numbers in the file: 69

The screenshot of the program and its output is attached.

Write a C++ Programm in which inheritance is used
geniusboy [140]

Answer:

// C++ program to demonstrate inheritance

#include <iostream>

   void eat() {

       cout << "I can eat!" << endl;

   }

   void sleep() {

       cout << "I can sleep!" << endl;

   }

};

// derived class

class Dog : public Animal {

  public:

   void bark() {

       cout << "I can bark! Woof woof!!" << endl;

   }

};

int main() {

   // Create object of the Dog class

   Dog dog1;

   // Calling members of the base class

   dog1.eat();

   dog1.sleep();

   // Calling member of the derived class

   dog1.bark();

   return 0;

}
