If you implement too many security controls, what portion of the CIA triad (Information Assurance Pyramid) may suffer?
a. Availability
b. Confidentiality
c. Integrity
d. All of the above
Answer:
Option A
Availability
Explanation:
The implementation of too many security protocols will lead to a reduction of the ease at which a piece of information is accessible. Accessing the piece of information will become hard even for legitimate users.
The security protocols used should not be few, however, they should be just adequate to maintain the necessary level of confidentiality and integrity that the piece of information should have, While ensuring that the legitimate users can still access it without much difficulty.

Write an interactive program to calculate the volume and surface area of a three-dimensional object.
Answer:
I am writing a Python program:
pi=3.14 #the value of pi is set to 3.14
radius = float(input("Enter the radius of sphere: ")) #prompts user to enter the radius of sphere
surface_area = 4 * pi * radius **2 #computes surface area of sphere
volume = (4.0/3.0) * (pi * radius ** 3) #computes volume of sphere
print("Surface Area of sphere is: ", surface_area) #prints the surface area
print("Volume of sphere is: {:.2f}".format(volume)) #prints the volume
Explanation:
Please see the attachment for the complete interactive code.
The first three lines of print statement in the attached image give a brief description of the program.
Next the program assigns 3.14 as the value of π (pi). Then the program prompts the user to enter the radius. Then it computes the surface area and volume of sphere using the formulas. Then it prints the resultant values of surface area and volume on output screen.
The psuedocode for this program is given below:
PROGRAM SphereVolume
pi=3.14
NUMBER radius, surface_area, volume
INPUT radius
COMPUTE volume = (4/3) * pi* radius ^3
COMPUTE surface_area = 4 * pi * radius ^ 2
OUTPUT volume , surface_area

Given an array of integers check if it is possible to partition the array into some number of subsequences of length k each, such that:
Each element in the array occurs in exactly one subsequence
For each subsequence, all numbers are distinct
Elements in the array having the same value must be in different subsequences
If it is possible to partition the array into subsequences while satisfying the above conditions, return "Yes", else return "No". A subsequence is formed by removing 0 or more elements from the array without changing the order of the elements that remain. For example, the subsequences of [1, 2, 3] are D. [1], [2], [3]. [1, 2], [2, 3], [1, 3], [1, 2, 3]
Example
k = 2.
numbers [1, 2, 3, 4]
The array can be partitioned with elements (1, 2) as the first subsequence, and elements [3, 4] as the next subsequence. Therefore return "Yes"
Example 2 k 3
numbers [1, 2, 2, 3]
There is no way to partition the array into subsequences such that all subsequences are of length 3 and each element in the array occurs in exactly one subsequence. Therefore return "No".

these are instructions to a question?
2- (8 point) Write a program using the instructions below. Assume that integers are stored in 4 bytes. a) Define an array of type int called apples with five elements, and initialize the elements to the even integers from 2 to 10. b) Define a pointer aPtr that points to a variable of type int. c) Print the elements of array values using a for statement. d) Write two separate statements that assign the starting address of the array to pointer variable aPtr. e) What physical address is aPtr pointing to? f) Print the elements of array values using pointer/offset notation. g) What address is referenced by aPtr + 3? What value is stored at that location? h) Assuming aPtr points to apples[4], what address is referenced by aPtr -= 4? What value is stored at that location?
Answer:
a)
int apples [5] = {2, 4, 6, 8, 10};
b)
int *aPtr //this is the pointer to int
Another way to attach a pointer to a an int variable that already exists:
int * aPtr;
int var;
aPtr = &var;
c)
for (int i = 0; i < size; i++){
cout << values[i] << endl; }
d)
aPtr = values;
aPtr = &values[0];
both the statements are equivalent
e)
If its referring to the part d) then the address is:
cout<<aPtr;
f)
for (int i = 0; i < size; ++i) {
cout<<*(vPtr + i)<<endl; }
g)
cout << (aPtr + 3) << endl; // address referenced by aPtr + 3
cout << *(aPtr + 3) << endl; // value stored at that location
This value stored at location is 8
h)
aPtr = &apples[4];
aPtr -= 4;
cout<<aPtr<<endl;
cout<<*aPtr<<endl;
Explanation:
a)
int apples [5] = {2, 4, 6, 8, 10};
In this statement the array names is apples, the size of the array is specified in square brackets. so the size is 5. The type of array apples is int this means it can store integer elements. The values or elements of the array apples are even integers from 2 to 10. So the elements of array are:
apples[0] = 2
apples[1] = 4
apples[2] = 6
apples[3] = 8
apples[4] = 10
b)
In this statement int *aPtr
The int* here is used to make the pointer aPtr points to integer object. Data type the pointer is pointing to is int. The asterisk symbol used with in makes this variable aPtr a pointer.
If there already exists an int type variable i.e. var and we want the pointer to point to that variable then declare an int type pointer aPtr and aPtr = &var; assigns the address of variable var to aPtr.
int * aPtr;
int var;
aPtr = &var;
c)
The complete program is:
int size= 5;
int values[size] = {2,4,6,8,10};
for (int i = 0; i < size; i++){
cout << values[i] << endl; }
The size of array is 5. The name of array is values. The elements of array are 2,4,6,8,10.
To print each element of the values array using array subscript notation, the variable i is initialized to 0, because array index starts at 0. The cout statement inside body of loop prints the element at 0-th index i.e. the first element of values array at first iteration. Then i is incremented by 1 each time the loop iterates, and this loop continues to execute until the value of i get greater of equal to the size i.e. 5 of values array.
The output is:
2
4
6
8
10
d)
aPtr = values;
This statement assigns the first element in values array to pointer aPtr. Here values is the address of the first element of the array.
aPtr = &values[0];
In this statement &values[0] is the starting address of the array values to which is assigned to aPtr. Note that the values[0] is the first element of the array values.
e)
Since &values[0] is the starting address of the array values to which is assigned to aPtr. So this address is the physical address of the starting of the array. If referring to the part d) then use this statement to print physical address is aPtr pointing to
cout<<aPtr;
This is basically the starting address of the array values to which is assigned to aPtr.
The output:
0x7fff697e1810
f)
i variable represents offset and corresponds directly to the array index.
name of the pointer i.e. vPtr references the array
So the statement (vPtr + i) means pointer vPtr that references to array values plus the offset i array index that is to be referenced. This statement gives the address of i-th element of values array. In order to get the value of the i-th element of values array, dereference operator * is used. It returns an ith value equivalent to the address the vPtr + i is pointing to. So the output is:
2
3
6
8
10
g)
values[0] is stored at 1002500
aPtr + 3 refers to values[3],
An integer is 4 bytes long,
So the address that is referenced by aPtr + 3 is
1002500 + 3 * 4 = 1002512
values[3] is basically the element of values array at 3rd index which is the 4th element of the array so the value stored at that referred location is 8.
h)
Given that aPtr points to apples[4], so the address stored in aPtr is
1002500 + 4 * 4 = 1002516
aPtr -= 4 is equivalent to aPtr = aPtr - 4
The above statement decrements aPtr by 4 elements of apples array, so the new value is:
1002516 - 4 * 4 = 1002500
This is the address of first element of apples array i.e 2.
Now
cout<<aPtr<<endl; statement prints the address referenced by aPtr -= 4 which is 1002500
cout<<*aPtr<<endl; statement prints the value is stored at that location which is 2.
Write down the short history of COMPUTER?
Answer:
Charles Babbage, an English mechanical engineer and polymath, originated the concept of a programmable computer. Considered the "father of the computer",he conceptualized and invented the first mechanical computer in the early 19th century.
. In the select algorithm that finds the median we divide the input elements into groups of 5. Will the algorithm work in linear time if we divide it into groups of 7? How about 3? Explain your answer--- the asymptotic run time in either case.
Answer:
we have that it grows more quickly than linear.
Explanation:
It will still work if they are divided into groups of 77, because we will still know that the median of medians is less than at least 44 elements from half of the \lceil n / 7 \rceil⌈n/7⌉ groups, so, it is greater than roughly 4n / 144n/14 of the elements.
Similarly, it is less than roughly 4n / 144n/14 of the elements. So, we are never calling it recursively on more than 10n / 1410n/14 elements. T(n) \le T(n / 7) + T(10n / 14) + O(n)T(n)≤T(n/7)+T(10n/14)+O(n). So, we can show by substitution this is linear.
We guess T(n) < cnT(n)<cn for n < kn<k. Then, for m \ge km≥k,
\begin{aligned} T(m) & \le T(m / 7) + T(10m / 14) + O(m) \\ & \le cm(1 / 7 + 10 / 14) + O(m), \end{aligned}
T(m)
≤T(m/7)+T(10m/14)+O(m)
≤cm(1/7+10/14)+O(m),
therefore, as long as we have that the constant hidden in the big-Oh notation is less than c / 7c/7, we have the desired result.
Suppose now that we use groups of size 33 instead. So, For similar reasons, we have that the recurrence we are able to get is T(n) = T(\lceil n / 3 \rceil) + T(4n / 6) + O(n) \ge T(n / 3) + T(2n / 3) + O(n)T(n)=T(⌈n/3⌉)+T(4n/6)+O(n)≥T(n/3)+T(2n/3)+O(n) So, we will show it is \ge cn \lg n≥cnlgn.
\begin{aligned} T(m) & \ge c(m / 3)\lg (m / 3) + c(2m / 3) \lg (2m / 3) + O(m) \\ & \ge cm\lg m + O(m), \end{aligned}
T(m)
≥c(m/3)lg(m/3)+c(2m/3)lg(2m/3)+O(m)
≥cmlgm+O(m),
therefore, we have that it grows more quickly than linear.
When a user runs a program in a text-based environment, such as the command line, what determines the order in which things happen?
Explanation:
In general, when a program runs in text-based environment like command line interface, the program is used for determining the order in which things happen.
As the program runs, the user will not have any choice and he or she can enter the required data.
If the user enters the data in required format then, he/she can get the result or output in desired format.
Write a CashRegister class that can be used with the RetailItem class that you wrote in Chapter 6's Programming Challenge 4. The CashRegister class should simulate the sale of a retail item. It should have a constructor that accepts a RetailItem object as an argument. The constructor should also accept an integer that represents the quantity of items being purchased. In addition, the class should have the following methods:
• The getSubtotal method should return the subtotal of the sale, which is the quantity multiplied by the price. This method must get the price from the RetailItem object that was passed as an argument to the constructor.
• The getTax method should return the amount of sales tax on the purchase. The sales tax rate is 6 percent of a retail sale.
• The getTotal method should return the total of the sale, which is the subtotal plus the sales tax.
Demonstrate the class in a program that asks the user for the quantity of items being purchased and then displays the sale’s subtotal, amount of sales tax and total.
Answer:
Following are the code to this question:
import java.util.*; //import package for user input
class RetailItem//defining class RetailItem
{
private String desc;//defining String variable
private int unit;//defining integer variable
private double prices;//defining double variable
RetailItem()//defining default Constructor
{
//Constructor body
}
Output:
The Sub Total value: 199.75
The Sales Tax value: 11.985
The Total value: $211.735
Explanation:
In the above code three class "RetailItem, CashRegister, and Main" is defined, in the class "RetailItem", it defines three variable that is "desc, unit, and prices", inside the class "get and set" method and the constructor is defined, that calculates its value.
In the next step, class "CashRegister" is defined, and inside the class parameterized constructor is defined, which uses the get and set method to return its value.
In the next step, the main class is declared, in the main method two-class object is created and calls its method that are "getSubtotal, getTax, and getTotal".
