List and briefly defined categories of security services.
Fynjy0 [20]
There are six categories of security services: authenticiation, access control, data confidentiality, data integrity, nonrepudiation, and availability service. First, is authentication service, which defines as the assurance that the communicator is legitimate and is the one that it claims to be. It can either be peer entity or data origin authentication. Second, access control which is to prevent any unauthorized uses of resources. After one is being authenticiated, then this service limit/controls who access? what accessing rights to the resources are allowed depending on the identified individuals. Data confifentiality: the protection of data from unauthorized disclosure. Data integrity: the assurance that data received are exactly as sent by an authorized entity (e.t.c, contain no modificafion, insertion, deletion, or replay).

A palindrome is any word, phrase, or sentence that reads the same forward and backward. Here are some well-known palindromes: Ab
Pavlova-9 [17]

Answer:

Following are the program in the C++ Programming Language.

//header file

#include <iostream>

//header file for string

#include <string>

#include<cstring>

//using namespace

using namespace std;

//define Function to checks the string is passed is a Palindrome or not

bool is_Palin(string strng, int start_Position, int end_Position)

{

//set the if Conditional statement

if(start_Position >= end_Position)

{

return true;

}

//Check if the character is not the alphabet

if(!isalpha(strng[start_Position]))

{

//Update the starting position  

start_Position += 1;

//call Recursive function

return is_Palin(strng, start_Position++, end_Position);

}

//Check if the character is not the alphabet

if(!isalpha(strng[end_Position]))

{

//Update the end position

end_Position -= 1;

//call Recursive function

return is_Palin(strng, start_Position, end_Position--);

}

//Check if the characters are same or not same

if(tolower(strng[start_Position]) != tolower(strng[end_Position]))

{

return false;

}

//Update the positions

start_Position = start_Position + 1;

end_Position = end_Position - 1;

//call Recursive function

return is_Palin(strng, start_Position, end_Position);

}

//define Main function

int main()

{

string strng;

//get string from the user

cout << "\n\n Enter a string: ";

getline(cin, strng);

//Check for the palindrome

if(is_Palin(strng, 0, strlen(strng.c_str())-1))

{

 //then print message

cout << "\n Is a Palindrome!!!! \n";

}

//otherwise

else

{

//then print message

cout << "\n Is not a Palindrome!!!! \n";

}

return 0;

}

<u>Output:</u>

Enter a string:  Able was I, ere I saw Elba

Is a Palindrome!!!!

Explanation:

Here, we define a boolean data type function "is_Palin" to check the string which passed through is palindrome or not and pass and pass two integer type arguments for starting position and ending position and pass one string data type argument to pass string, inside the function.

  • Set the if conditional statement to check the condition if the start_position of the string is greater than end _position of the string then return true.
  • Set the if conditional statement to check the condition the start_position of the staring is alphabet then, update the start_position and call the recursion function.
  • Again set the if conditional statement to check the condition the end_position of the staring is alphabet then, update the end_position and call the recursion function.
  • Set the if conditional statement to check the condition if the start_position of the string is not equal to the end _position of the string then, return false.
  • Then, update the start_position and end _position of the string increment by 1 then, call the recursive function and then, close the function.

Finally, we define the main function and pass string through calling and passing and argument list in its parameter.
