Answer:

c. Buffer overflow

Explanation:

In Computer programming, buffer can be defined as an area of memory set aside specially and specifically for holding data or informations.

A type of exploit that relies on overwriting contents of memory to cause unpredictable results in an application is known as buffer overflow. This ultimately implies that, buffer overflow is the process of exceeding the storage capacity of a memory buffer with data, beyond the amount it is designed to hold and therefore overwrites any adjacent memory locations.

Buffer overflow attacks are becoming less common in modern operating systems because the modern operating system usually leaves a space between buffers and randomize the layout of memory through call mapping, as well as through the use of runtime protection.

D)One big superclass can be used instead of many little classes.

Explanation:

Inheritance could be described as getting new class on another existing class with almost same execution,

inheritance allows codes to be re-used. It should be noted that inheritance bring about the code sharing among class.

The advantages of using inheritance includes but not limited to

✓ Code that is shared between classes needs to be written only once.

✓Similar classes can be made to behave consistently.

✓ Enhancements to a base class will automatically be applied to derived classes.

A major disadvantage of inheritance is that child/children classes depends on parent class, hence a change in the parent class will affect the child class, therefore option C is the correction option.

Inheritance is a type of programming concept where by a class (Child) can inheritance methods, properties of another class (Parent).

Inheritance allows us to reuse of code, one advantage of Inheritance is that the code that is already present in base class need not be rewritten in the child class.

Here is the C++ program that simulates lottery:

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

using namespace std;  //to access objects cin cout

int main(){  //start of main function

int size= 5; // size of arrays

int range = 10;  //range of random numbers from 0 to 9

int user[size];  // user array

int lottery[size];  // lottery array

for(int i=0;i<size;i++)  //iterates through the array

lottery[i]=rand()%range;  // generates random number in specified range

cout<<"Enter "<<size<<" digits: ";  //prompts user to enter 5 digits

for(int i=0;i<size;i++)  //loops through the user array

cin>>user[i];  //reads input digits from user

int match=0;  //stores number of matching digits

for(int i=0;i<size;i++)  //iterates through array to compare user and lottery arrays

if(user[i]==lottery[i])  //if digit at i-th index of user array matches to that of lottery array

match++;  //increments count of matching digits by 1

cout<<"Lottery array: ";  // display digits of lottery array

for(int i=0;i<size;i++)  //iterates through elements of lottery array

cout<<lottery[i]<<" ";  //prints elements of lottery array with a space between them

cout<<endl;  //prints a new line

cout<<"  User  array: ";  // prints digits of user array

for(int i=0;i<size;i++) //iterates through elements of user array

cout<<user[i]<<" ";  //prints elements of user array

cout<<endl;  // prints a new line

if(match==size){  //if all the digits match

cout<<"Congratulations. You are a grand prize winner! "; }//displays this message proclaiming the user as a grand prize winner

else{  // if all digits of user array do not match with lottery array digits

cout<<"Number of digits matched: "<<match<<endl; //displays the number of matched digits

cout<<"Sorry! Better luck next time!" ;    //displays this message when all digits don't match

}

}    

Explanation:

If you want to keep the size and range fixed then you can use #define before the main() function to give a constant value to size and range as:

#define size 5

#define range 10

The program uses rand() function in order to generate random numbers for lottery array in the range of 0 through 9.

Then the program declares a user array with size = 5 and prompts user to enter 5 digits to stores in user array.

Next the program matches each digit of user array to the corresponding digit of lottery array and if the two digits match then the program increments the match variable by 1 to count the matched digits. For example, lets say lottery has the following elements:

lottery: 7,4,9,1,3

Lets say user array has following elements input by user at console

user: 4,2,9,7,3

Now at first iteration the digit 7 at 0-th index of lottery array is matched to the digit 4 at 0-th index of user array. This index is specified using variable i. These means the first element of lottery array is matched with first element of user array. As these digits are not equal so they don't match and the variable i is incremented to point to the position of next digit.

Now at second iteration the digit 4 in lottery array is matched to the digit 2 of user array. As these digits are not equal so they don't match and the variable i is incremented.

at third iteration the digit 9 in lottery array is matched to the digit 9 of user array. As these digits equal so they match and the variable match is incremented to 1 in order to count the number of matches. So value of match = 1

Now at fourth iteration the digit 1 in lottery array is matched to the digit 7 of user array. As these digits are not equal so they don't match and the variable i is incremented. The value of match also remains the same i.e. 1

at fifth iteration the digit 3 in lottery array is matched to the digit 3 of user array. As these digits equal so they match and the variable match is incremented to 1 in order to count the number of matches. So value of match = 2

Next the loop ends because the value of exceeds 5 which is the size of the array.

Next if(match==size) statement has an if condition which checks if all digits match. This is checked by comparing the count of match variable to the size of the array. The value of match is 2 and value of size is 5 so this means that all the digits do not match. Hence this condition evaluates to false. So the statement in if part will not execute and program moves to the statement: cout<<"Number of digits matched: "<<match<<endl; which displays the value of match variable i.e. 2 as:

Number of digits matched: 2

followed by statement cout<<"Sorry! Better luck next time!" ;  which displays the message:

Sorry! Better luck next time!

public class Main {

public static void main(String[] args) {  //start of main function body

 String num1, num2,num3;  //declare three variables to store strings of numbers for input dialog

 double number1, number2, number3, sum,product; //declare three double type variables to hold the real numbers  

 num1 = JOptionPane.showInputDialog("num1");  //shows a dialog box prompting user to enter value of first number i.e. num1

 number1 = Double.parseDouble(num1);  //scans and reads the value of first input number i.e. number1    

 num2 = JOptionPane.showInputDialog("num2");  //shows a dialog box prompting user to enter value of second number i.e. num2

 number2 = Double.parseDouble(num2);   //reads number2  

               num3 = JOptionPane.showInputDialog("num3");  //shows a dialog box prompting user to enter value of third number i.e. num3

 number3 = Double.parseDouble(num3);   //reads number3  

   if(number1>0&& number2>0 && number3>0){  //checks if all three numbers are positive

   sum = number1 + number2+ number3;  //displays the sum by adding all three positive numbers

   JOptionPane.showMessageDialog(null, "the sum is : " + sum , "Results", JOptionPane.PLAIN_MESSAGE );      }   // displays the result of sum in a message dialog box

    if(number1<0 && number2>0 && number3>0)      {  //checks if number2 and number3 are positive

   product = number2*number3;  //computes product

   JOptionPane.showMessageDialog(null, "the product is : " + product , "Results", JOptionPane.PLAIN_MESSAGE );      }  //displays the result

   else if (number2<0&&number1>0&&number3>0){  //checks if number1 and number3 are positive

    product = number1*number3;  //computes product

   else     {  /.if all the numbers are positive.

/*However this part is optional. You can just use else part for above else if statement and exclude this else part. In this way the product of all three positive numbers is not computed and product is only computed when only two numbers of the three are positive */

     product = number1*number2*number3;  //computes product of all three positive numbers

     JOptionPane.showMessageDialog(null, "the product is : " + product , "Results", JOptionPane.PLAIN_MESSAGE );      }   //displays the result

Scanner scan = new Scanner(System.in);  //creates a Scanner class object

double value1 , value2, quotient;  //declares variables to hold the values of two real numbers and the result of division of the two real numbers is stored in quotient variable

System.out.println("Enter the first real number: ");  //prompts user to enter the value of first real number from the console

value1 = scan.nextDouble();  //reads the first number from user

System.out.println("Enter the second real number : ");  //prompts user to enter the value of second real number from the console

value2 = scan.nextDouble();  //reads the second number from user

if(value1<0&&value2<0)  {  //checks if both the numbers are negative

quotient = value1/value2;  //compute the quotient

JOptionPane.showMessageDialog(null, "the quotient is : " + quotient , "Results", JOptionPane.PLAIN_MESSAGE );    }  //displays result

 else  //if both numbers are not negative

JOptionPane.showMessageDialog(null, "Both numbers are not negative" );   //displays this message in a dialog box

  }  }

Explanation:

In the above given code if you want to display the outputs in console then alter the following statements as follows:

   if(number1>0&& number2>0 && number3>0){

   sum = number1 + number2+ number3;

  System.out.println("the sum is :  " + sum); }      

    if(number1<0 && number2>0 && number3>0)      {

    product = number2*number3;

      System.out.println("the product is :  " + product); }          

   else if (number2<0&&number1>0&&number3>0){

          product = number1*number3;

System.out.println("the product is :  " + product);      }

   else if (number3<0 && number1>0 && number2>0)     {

     product = number1*number2;

     System.out.println("the product is :  " + product);     }

   else     {

     product = number1*number2*number3;

      System.out.println("the product is :  " + product);      }

Scanner scan = new Scanner(System.in);

double value1 , value2, quotient;

System.out.println("Enter the first real number: ");

value1 = scan.nextDouble();

System.out.println("Enter the second real number : ");

value2 = scan.nextDouble();

if(value1<0&&value2<0)  {

quotient = value1/value2;

 System.out.println("the quotient is :  " + quotient);   }

 else  

System.out.println("Both numbers are not negative");

Notice that all the JOptionPane.showMessageDialog statement are changed with System.out.println which prints the results on the console.
