The principal object of a hash function is __________ .
a. data integrity
b. compression
c. collision resistance
d. mapping messages
Answer:
a. data integrity
Explanation:
In Computer science, a hash function can be defined as any function which is used to map data by accepting a block of data with variable length size or arbitrary size as input to produce a fixed size hash values or codes.
Generally, when a block of data (input) of arbitrary size is hashed, the resulting hash values or codes is usually smaller than the input data. Thus, hash functions are considered to be a compression of data and as a result, sometimes called compression functions. Basically, the block size of a hash function typically ranges from 128 bits to 512 bits.
Some of the properties of a hash function are;
1. Pre-image resistance: this makes it practically impossible to reverse a fixed-size hash values to its initial arbitrary size. This property helps to maintain and enhance data integrity by making it difficult or impossible for an attacker to find the input data from a hash value.
2. Second pre-image resistance: this property makes it near impossible or very difficult to determine or decode another input data from a given set of input and hash values. Also, this helps to enhance data integrity.
3. Collision resistance: this is to make possible for all hash values to have a unique value. This simply means that, with this property it would be difficult for different input data to have the same hash value. Thus, it helps to create integrity in data management.
Hence, with the aforementioned properties, the principal object of a hash function is data integrity.
Hash functions in the computer world includes;
1. Message Digest (MD): it is a 128 bit hash function and comprises of the following; MD2, MD4, MD5, and MD6.
2. Secure Hash Function (SHA): it comprises of the following; SHA-0, SHA-1,SHA-2, and SHA-3.
3. Whirlpool: it comprises of the following; Whirlpool-0, Whirlpool-T, and Whirlpool. It is primarily a 512 bit hash function.
4. RACE Integrity Primitives Evaluation Message Digest (RIPEMD): it comprises of the following versions; RIPEMD, RIPEMD-128, and RIPEMD-160.
A customer in a store is purchasing five items. The prices of the five items are Price of item 1 = $15.95 Price of item 2 = $24.95 Price of item 3 = $6.95 Price of item 4 = $12.95 Price of item 5 = $3.95 Write a program that holds the prices of the five items in five variables. Display each item’s price, the subtotal of the sale, the amount of sales tax, and the total. Assume the sales tax is 7%
Answer:
Follows are the code to this question:
#include<iostream>//defining a header file
using namespace std;
int main ()//defining a main method
{
float SubTotal,SalesTax,Total;//defining float variable for calculate the value
float item_1 = 15.95, item_2 = 24.95,item_3 = 6.95, item_4 = 12.95,item_5 = 3.95;//defining float variable and assign value
SubTotal = item_1+item_2+item_3+item_4+item_5;//use SubTotal to calculate the sum
SalesTax = SubTotal * 0.07;//use SalesTax to calculate 7% of SubTotal
Total = SubTotal + SalesTax ;//use Total to addd SubTotal and SalesTax
cout << "Price of item 1 : $"<< item_1 << endl;//print item_1 Price
cout << "Price of item 2 : $"<< item_2 <<endl;//print item_2 Price
cout << "Price of item 3 : $"<< item_3 <<endl;//print item_3 Price
cout << "Price of item 4 : $"<< item_4 <<endl;//print item_4 Price
cout << "Price of item 5 : $"<< item_5 <<endl;//print item_5 Price
cout <<"The SubTotal value is: $"<< SubTotal << endl;//print SubTotal value
cout <<"The SalesTax value is: $"<< SalesTax << endl;//print SalesTax value
cout << "The Total value is: $" << Total << endl;//print Total value
return 0;
}
output:
please find attached file.
Explanation:
In the above-given code, three float variable that are "SubTotal, SalesTax, and Total" is define for calculating and store its value, and in the next line, another five float variable " item_1, item_2, item_3, item_4, and item_5" is declared that stores a float value which is defined in the question.
In the next line, the "SubTotal" variable is used to add the value of all items, and in the next line, the SalesTax is used to calculate the 7% of SubTotal and store its value. At the last, the "Total" variable is defined that adds the "SubTotal and SalesTax" value and uses the print method to print all variable values.Which class describes a container for an application?

Write an expression that will cause the following code to print "I am a teenager" if the value of userAge is less than 20. Zybooks won't let me edit any other line, and UserAge > 20 was marked wrong. It won't accept the ≥ symbol either.
Answer:
Replace
if userAge > 20
with
userAge > 19
Explanation:
if userAge > 20 checks if age is 21, 22, 23, 24........
The else condition which prints "I am a teenager" checks if age is 20, 19, 18....
Notice that 20 is inclusive of the else condition; this shouldn't be because for userAge to be less than 20, 20 isn't inclusive
To solve this,
Replace if userAge > 20 with userAge > 19
So that, the else
The else condition which prints "I am a teenager" checks if age is 19, 18, 17, 16....

List two items that are required to make a text file into a bash script.
Answer:
Explanation:
First a header is needed indicating which bash will be used (sh, zsh, bash, etc.), then it is necessary to change the file extension so that the system recognizes it as an executable file and no longer as text
In order for the system to recognise the file as an executable file rather than a text file, a header indicating which bash will be used is first required (sh, zsh, bash, etc.).
What is bash script?A file containing a succession of commands is called a bash script. The bash programme reads and processes these.
The computer programme runs line by line. For instance, you can use the command line to travel to a specific path, create a folder, and spawn a process inside of it.
Run the "cat" command and then use the redirection operator ">" and the filename to create a new file. You will now be asked to add data to this just created file. To save the file, type line and then hit "Ctrl+D."
A header stating which bash will be used is first necessary for the system to recognise the file as an executable file as opposed to a text file (sh, zsh, bash, etc.).
Thus, these are the two items that are required to make a text file into a bash script.

Given an integer n and an array a of length n, your task is to apply the following mutation to a:
Array a mutates into a new array b of length n.
For each i from 0 to n - 1, b[i] = a[i - 1] + a[i] + a[i + 1].
If some element in the sum a[i - 1] + a[i] + a[i + 1] does not exist, it should be set to 0. For example, b[0] should be equal to 0 + a[0] + a[1].
Example
For n = 5 and a = [4, 0, 1, -2, 3], the output should be mutateTheArray(n, a) = [4, 5, -1, 2, 1].
b[0] = 0 + a[0] + a[1] = 0 + 4 + 0 = 4
b[1] = a[0] + a[1] + a[2] = 4 + 0 + 1 = 5
b[2] = a[1] + a[2] + a[3] = 0 + 1 + (-2) = -1
b[3] = a[2] + a[3] + a[4] = 1 + (-2) + 3 = 2
b[4] = a[3] + a[4] + 0 = (-2) + 3 + 0 = 1
So, the resulting array after the mutation will be [4, 5, -1, 2, 1].
Answer:
let a = [4, 0, 1, -2, 3];
let b = a.map( (e, i, arr) => (arr[i-1] || 0)+arr[i]+(arr[i+1] || 0) );
console.log(b);
Explanation:
The map operator is excellent for this. The || 0 operator prevents the undefined out of bounds value from ruining the result.

We have seen that Internet TCP sockets treat the data being sent as a byte stream but UDP sockets recognize message boundaries. What are one advantage and one disadvantage of byte-oriented API versus having the API explicitly recognize and preserve application-defined message boundaries
Answer:
One advantage of byte-oriented APIs is that all byte of the data sent by the API is retrieved but for APIs with application-defined message boundaries, some bytes of data could be lost in the streaming process.
One disadvantage of byte-oriented APIs is the time it takes to resend a byte increases its propagation delay, while the is an advantage of the APIs with application-defined message boundaries as it does not have to resend any lost bytes of data, making it faster.
Explanation:
Note that byte-oriented APIs uses the TCP socket which resends lost bytes of data and application-defined message boundaries APIs uses the UDP protocol to send data but does not resend if lost.

Write a program in c++ that plays a number guessing game with a Human user. The Human user will think of a number between 1 and 100, inclusive. The program will make guesses and the user will tell the program to guess higher or lower. A sample run of the program might look like this: Ready to play (y/n)? y Think of a number between 1 and 100. My guess is 50. Enter 'l' if your number is lower, 'h' if it is higher, 'c' if it is correct: h My guess is 75. Enter 'l' if your number is lower, 'h' if it is higher, 'c' if it is correct: h My guess is 88. Enter 'l' if your number is lower, 'h' if it is higher, 'c' if it is correct: l My guess is 81. Enter 'l' if your number is lower, 'h' if it is higher, 'c' if it is correct: c Great! Do you want to play again (y/n)? y Think of a number between 1 and 100. My guess is 50. Enter 'l' if your number is lower, 'h' if it is higher, 'c' if it is correct: l My guess is 25. Enter 'l' if your number is lower, 'h' if it is higher, 'c' if it is correct: h My guess is 37. Enter 'l' if your number is lower, 'h' if it is higher, 'c' if it is correct: c Great! Do you want to play again (y/n)? n The strategy that the program will use goes like this: Every time the program makes a guess it should guess the midpoint of the remaining possible values. Consider the first example above, in which the user has chosen the number 81: On the first guess, the possible values are 1 to 100. The midpoint is 50. The user responds by saying "higher" On the second guess the possible values are 51 to 100. The midpoint is 75. The user responds by saying "higher" On the third guess the possible values are 76 to 100. The midpoint is 88. The user responds by saying "lower" On the fourth guess the possible values are 76 to 87. The midpoint is 81. The user responds "correct" Additional Requirements The purpose of the assignment is to practice writing functions. Although it would be possible to write the entire program in the main function, your solution should be heavily structured. Most of the point penalties given on this assignment will be for not following the instructions below carefully. The main function must look exactly like this. Copy and paste this code into your file, and don't edit it: int main() { char response; cout > response; while (response == 'y') { playOneGame(); cout > response; } } The playOneGame() function should implement a complete guessing game on the range of 1 to 100. The lower and upper bounds of the range should be assigned to global named constants and then not used again in your code. In addition, you should implement the following helper functions to be invoked inside your playOneGame() function: void getUserResponseToGuess(int guess, char& result) The getUserResponseToGuess() function should prompt the user to enter 'h', 'l', or 'c' (as shown in the sample output). It should set its "result" parameter equal to whatever the user enters in response. It should do this ONE time, and should not do anything else. Note that printing the guess is part of the prompt. int getMidpoint(int low, int high) The getMidpoint() function should accept two integers, and it should return the midpoint of the two integers. If there are two values in the middle of the range then you should consistently chose the smaller of the two.

Write a program that will convert a distance provided in inches to a distance in yards, feet and inches. The program will ask the user to input a distance in inches as a whole number. It will convert the distance provided into yards, feet and inches. Then it will display the distance in yards, feet and inches. For example, the program will convert 50 inches into 1 yard, 1 ft and 2 inches. See the Testing section for test data.
Answer:
Here is the C++ program:
#include <iostream> // to use input output functions
using namespace std; //to access objects like cin cout
int main() { //start of main method
int inches, feet, yards; // declare variables to hold values of inches, feet and yards
cout << "Enter distance in inches: " //prompts user to enter distance in inches
cin >> inches; //reads value of inches from user
feet = inches/12; // divides value of inches (performs integer division) by 12 and store result in feet
inches = inches%12; //takes modulo of inches with 12 and stores the result in inches variable
yards = feet / 3; // divides value of feet with 3 and stores result in yards
feet = feet % 3; //take modulo of value of feet with 3 and stores result in feet variable
cout<<"yards: "<<yards<<endl<<"feet: "<<feet<<endl<<"inches: "<<inches; }
//displays the value of inches into yards feet and inches
Explanation:
I will explain the program with an example:
Suppose the user enters 50 as distance.
inches = 50
feet = inches/12; this statement becomes:
feet = 50/12
The answer of division is 4.166667 but as we are doing integer division so there is no fractional part rather it is represented as whole number and remainder is ignored. So,
feet = 50/12
feet = 4
inches = inches%12; next is this statement which becomes:
inches = 50 % 12
% operator basically computes the remainder. So when 50 is divided by 12 it gives the quotient 4 in integer division and gives 2 as remainder. But we need the value of remainder so,
inches = 50 % 12
inches = 2
yards = feet / 3; next is this statement which becomes:
yards = 4 / 3
Since the value of feet computed in above steps is 4 so this value is divided by 3.
4/3 gives 1.333333 but as we are doing integer division so there is no fractional part rather it is represented as whole number and remainder is ignored. So,
yards = 4 / 3
yards = 1
feet = feet % 3; next is this statement which becomes:
feet = 4 % 3
% operator basically computes the remainder. So when 4 is divided by 3 it gives the quotient 1 in integer division and gives 1 as remainder. But we need the value of remainder so,
feet = 4 % 3
feet = 1
Hence the input distance in inches i.e. 50 is converted to 1 yard, 1 ft and 2 inches as:
yards = 1
feet = 1
inches = 2
If you want to make the program more interactive by dislaying the value of yards, feet and inches as singular and plural then use these if statement in main() function:
if(yards<=1) //checks if value of yard is 1 or less
cout<<yards<<" yard"; //displays 1 yard in singular
else //if value of yard is greater than 1
cout<<yards<<" yards"; //place an "s" with yard to represent value greater than 1
cout<<endl;
if(feet<=1) //checks if value of feet is 1 or less
cout<<feet<<" foot"; //display the value with "foot" representing singular value
else //if value of feet is greater than 1
cout<<feet<<" feet"; //display the value with "feet"
cout<<endl;
if(inches<=1) //checks if value of inches is 1 or less
cout<<inches<<" inch"; //displays 1 inch in singular
else //if value of inches is greater than 1
cout<<inches<<" inches"; //place an "s" with yard to represent value greater than 1
The output of the program is attached.
