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:

C++ code explained below

Explanation:

#include<bits/stdc++.h>

#include <iostream>

using namespace std;

int FiboNR(int n)

{

int max=n+1;

int F[max];

F[0]=0;F[1]=1;

for(int i=2;i<=n;i++)

{

F[i]=F[i-1]+F[i-2];

}

return (F[n]);

}

int FiboR(int n)

{

if(n==0||n==1)

return n;

else

return (FiboR(n-1)+FiboR(n-2));

}

int main()

{

long long int i,f;

double t1,t2;

int n[]={1,5,10,15,20,25,30,35,40,45,50,55,60,65,70,75};

end = clock();

t2=double(end-begin);

cout<<n[i]<<" "<<t1*1.0/CLOCKS_PER_SEC <<" "<<t2*1.0/CLOCKS_PER_SEC <<" "<<f<<endl; //elapsed time in seconds

}

return 0;

Write a program to compute answers to some basic geometry formulas. The program prompts the user to input a length (in centimete

Svetlanka [38]

Answer:

import math

l = float(input("Enter length in cm: "))

l = l / 100;

print("Entered length is " + str(l) + " meters")

area_square = l * l

print("Area of square is " + str(area_square))

area_circle = math.pi * l/2 * l/2

print("Area of circle is " + str(area_circle))

volume_cube = l * l * l

print("Volume of cube is " + str(volume_cube))

Explanation:

*The code is in Python

Ask the user to enter the length in cm

Convert the length to meters and print it

Calculate the area of the square and print it (Since length is equal to a side, the area is length * length)

Calculate the area of the circle and print it (Since length is equal to the diameter, you need to divide it by two to get the radius. The area is pi * length/2 * length/2)

Calculate the volume of the cube and print it (Since length is equal to a side, the volume is length * length * length)

Design a class named Cake. Data fields include two string fields for cake flavor and icing flavor and numeric fields for diamete

kkurt [141]

Using the computer language in pseudocode to write a function code that declares two Cake objects and sets and displays their values.

<h3>Writting the code in pseudocode:</h3>

- cake flavor: string

- icing flavor: string

-diameter: num

-price: num

+set cake flavor (cake flavor : string) : void

+set icing flavor (icing flavor: string) : void

+set Diameter(size : num) : void

+set Price(price : num) : void

+get cake flavor () : string

+get cing flavor () : string

+get Diameter() : num

+get Price() : num

Answer A=

Pseudocode:

class Cake

Declarations

private string cake flavour

private string icing flavor

private num diameter

private num price

public void set Cake flavour (string Cake flavour)this. Cake flavour = Cake flavour

return

public void set icing flavour (string icing flavour)this. icing flavour = icing flavour

return

public void set Diameter(num size)

diameter = size

return

public void set Price(num price)

this price = price

return

public string get Cake flavour ()

return Cake flavour

public string get icing flavour ()

return icing flavour

public num get Diameter()

return diameter

public num get Price()

return price

end Class

start

Declarations

Cake my Cake

Cake your Cake

myCake.set cake flavour (“chocalate”)

myCake.set icing flavour (“peppermint”)

myCake.setDiameter(15)

myCake.setPrice(18)

myCake.set cake flavour (“pineapple”)

myCake.set icing flavour (“orange ”)

yourCake.setDiameter(20)

yourCake.setPrice(25)

output “Cake 1 info:”

output myCake.get cake flavour ()

output myCake.get icing flavour ()

output myCake.getDiameter()

output myCake.getPrice()

output Cake 2 info:”

output yourCake.get cake flavour ()
