Answer:
Explanation:
1. Write a program that declares an array named alpha with 50 components of the type double. Initialize the array so that the first 25 components are equal to the square of the counter (or index) variable and the last 25 components are equal to three times the index variable.
double alpha[50];
for (int i=0;i<25;i++)
{
alpha[i]=i*i;
alpha[i+25]=(i+25)*3;
}
2. Output the array so that exactly ten elements per line are printed.
for (int i=0;i<50;i++)
{
cout<<i+1<<". "<<alpha[i]<<" ";
if (((i+1)%10)==0)
{
cout<<endl;
}
}
3. Run your program again, but this time change the code so that the array is filled with random numbers between 1 and 100.
double alpha[50];
for (int i=0;i<50;i++)
{
alpha[i]=rand()%101;
}
for (int i=0;i<50;i++)
{
cout<<i+1<<". "<<alpha[i]<<" ";
if (((i+1)%10)==0)
{
cout<<endl;
}
}
4. Write the code that computes and prints the average of elements of the array.
double alpha[50],temp=0;
for (int i=0;i<50;i++)
{
alpha[i]=rand()%101;
temp+=alpha[i];
}
cout<<"Average :"<<(temp/50);
5. Write the code that that prints out how many of the elements are EXACTLY equal to 100.
double alpha[50],temp=0;
for (int i=0;i<50;i++)
{
alpha[i]=rand()%101;
if(alpha[i]==100)
{
temp++;
}
}
cout<<"Elements Exacctly 100 :"<<temp;
Please note: If you put each of above code to the place below comment it will run perfectly after compiling
#include <iostream>
using namespace std;
int main()
{
// If you put each of above code here it will run perfectly after compiling
return 0;
}

Answer:
c. An active attack
d. A passive attack
Explanation:
Traffic flow analysis is a cyber attack method of acquiring information by intercepting and examining messages so as to decode them by analysing patterns in the way the messages are communicated.
Traffic flow analysis can either be active or passive depending on if the attacker alters communication in the case of active analysis or simply extracts information in case of passive analysis.
Answer:
import sys
import turtle
import random
def n_pointed_star(total_points):
if total_points <= 4:
raise ValueError('Not enough total_points')
area = 150
for coprime in range(total_points//2, 1, -1):
if greatest_common_divisor(total_points, coprime) == 1:
start = turtle.position()
for _ in range(total_points):
turtle.forward(area)
turtle.left(360.0 / total_points * coprime)
turtle.setposition(start)
return
def greatest_common_divisor(a, b):
while b != 0:
a, b = b, a % b
return a
turtle.reset()
n_pointed_star(5)
Explanation:
- Inside the n_pointed_star function, check whether the total no. of points are less than or equal to 4 and then throw an exception.
- Loop through the total_points variable and check whether the result from greatest_common_divisor is equal to 1 or not and then set the starting position of turtle and move it.
- Create the greatest_common_divisor which takes two parameters a and b to find the GCD.
- Finally reset the turtle and call the n_pointed_star function.
