Write a program that simulates a lottery. The program should havean array of five integers named lottery, and shouldgenerate a random number in the range of 0 through 9 for eachelement in the array. The user should enter five digits whichshould be stored in an integer array named user. Theprogram is to compare the corresponding elements in the two arraysand keep a count of the digits that match. For example, thefollowing shows the lottery array and the user array with samplenumbers stored in each. There are two matching digits (elements 2and 4).
lottery array: 7,4,9,1,3
user array: 4,2,9,7,3
The program should display the random numbers stored in the lotteryarray and the number of matching digits. If all the digits match,display a message proclaiming the user as a grand prize winner.
Answers
Answer:
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!

Which of the following is used to encrypt web application data?
a. MD5
b. AES
c. SHA
d. DHA
Answers
Answer:
b. AES
Explanation:
AES is an acronym for Advanced Encryption Standard and it is a cryptographic or symmetric block cipher that is based on a substitution-permutation network (SPN) used for the encryption of sensitive data over the internet or web. AES uses a key length of 128, 192 or 256 bits and a block length of 128 bits to encrypt data on web applications.
It is an encryption standard of the government of the United States of America and is supported by the National Institute of Standards and Technology (NIST).
Hence, AES is used to encrypt web application data and it uses an algorithm developed by Vincent Rijmen and Joan Daemen, known as the Rijndael algorithm.

Answer:
d. all of the above are true
Explanation:
Connectionless Packet Switching is a term that is used in computer networking operations to describe the breaking of information exchange path into a various packet of small sizes acquired and refined over network switches and routers, which is then transferred from one subsequent node to the other. It is sometimes referred to as Datagram Networks
However, during this operation, Connectionless Packet Switching must satisfy the following amongst others:
1. each datagram must comprise both source and destination addresses
2. without a connection, datagrams may not come in sequential order at the destination
3. establishment of a connection between communicating points is not needed prior to exchanging datagrams, thus reducing overhead communications

How do I fix the error?
Answers
Answer:
num = int(input("Enter a number: "))
print(num * 8)
Explanation:
I highlighted the parts that are added
Since you are getting an input from the user, you need to set the result to a variable. In this case, it is num.
Since it is a number, you need to specify the its type. In this case, it may be int.
Also, the quotation marks must be written as seen.
The corrected program which ensures that the program runs correctly is written thus :
num = int(input("Enter a number: ")
#user supplied input should be assigned to the varibale num
print(num * 8)
#multiplies num by 8 and displays the output.
The num variable in the second line isn't attached to any value, therefore, it will throw an error. The user input value should be attached to the variable, 'num' The second line of code multiplies num by 8 and displays the product.Therefore, if the the user input is 3 ; the final result displayed will be : (3 × 8) = 24.

In Cybersecurity, vulnerability can be defined as any weakness, flaw or defect found in a software application or network and are exploitable by an attacker or hacker to gain an unauthorized access or privileges to sensitive data in a computer system.
This ultimately implies that, vulnerability in a network avail attackers or any threat agent the opportunity to leverage on the flaws, errors, weaknesses or defects found in order to compromise the security of the network.
Some of the ways to prevent vulnerability in a network are;

2. You should use a two-way authentication service.
3. You should use encrypting software applications or services.
