Write a module that contains a function sqrt(y, tol=1e-6), which computes a square root of a number using Heron’s algorithm with guaranteed relative error less then tol. The module should run as a program that asks for user input and prints output when executed using run sqrt.py. Heron’s algorithms for finding x such that y = x^2 works as follows. First, you come up with an initial guess for x; think what it should be. Then, you update x using the following formula: xnew = 1/2 (xold + y/xold) . Computation ends once the relative deviation between x^2 and y is less then the required value.

Finish one part before you proceed to the next part. Turn in your source code, the content of each file (including the text files) and the snapshot of the execution results for each part.

Part One: Write a Python program, called myEncryption.py, which takes three inputs: (1) the name of a text file, called plain.txt, (2) a user input integer k in the range of (1-25) and (3) the name of an output file, called encrypted.txt. The program encrypts the file plain.txt using the Caesar cipher algorithm and outputs one encrypted file, called encypted.txt. The plain.txt is given.

Contents of plain.txt file:

Hint: The myEncryption.py program may have the following sketch of code. First, it defeins variables to take user input and open files (for read and write). Then it read the plain.txt file content line by line using the function readline(). You may need to use a while loop to control the number of loops to read the file content line by line. Your program also opens an output file for write. For each input character in a line read, it performs the encrypting operations and then writes the encrypted line characters to the output file.

           """Take user inputs.   Open files, i.e., outFile and inputFile. """

cipherCode = ""        #initialize the decrypted code

line = inputFile.readline().strip()        # read the first line from the input file

           while line!= "":           # The While loop controls to read until the end of the input file

        for ch in line:

                  """ Block of Python code to encrypt the character ch   """

                  cipherCode += chr(cipherValue) # Append the cipher character for ch to cipherCode

        outFile.write(cipherCode + "\n")

        line = inputFile.readline().strip()     # read next line from the input file

        cipherCode = ""

         """ Finally, close all the files. """

Part Two: Write a Python program, called myDecryption.py, which takes two inputs: (1) the encrypted file encrypted.txt from Part One, and (2) the same user input integer k in the range of (1-25) and decrypts the file encrypted.txt using the Caesar cipher algorithm and outputs one decrypted file, called producedPlain.txt.

Part Three: Compare the plain.txt (from Part One) and producedPlain.txt (from Part Two). Are those two text files identical? ______________________

Project 1 - OO Programming

Create a program that simulates cars racing and allows users to bet on the races ( start users with $100 )

In main, prompt the user to enter details needed to create 2 instances of the Car class you create.

Ask the user to bet on which car will win the race ( use the overridden << method to display car details ), ensure the bet is between 1 and the amount of money the user has currently.

Create a Car class that has attributes for name, make, model, quarter mile time, and max speed.

( You can reference https://www.0-60specs.com/0-60-times/ - or just make values up )

Add a method Race that accepts a reference to another instance of car for the car to race.

When racing, add a random -1.0 - 1.0 second adjustment to the quarter mile time to account for wind and other conditions.

return a string result that says which car wins the race and by how much time.

Display the results of the bet and the users new balance.

Allow the user to keep creating cars to race until they are done or out of money.

Drivers are concerned with the mileage

obtained by their automobiles. One driver has kept track of

several trips by recording miles driven and gallons used for

each trip. Develop a java program that uses a while statement

to input the miles driven and gallons used for each trip. The

program should calculate and display the miles per gallon

obtained for each trip and print the combined miles per gallon

obtained for all tankfuls up to this point.

Enter miles driven (-1 to quit): 287

Enter gallons used: 13

MPG this trip: 22.076923

Total MPG: 22.076923

Enter miles driven (-1 to quit): 200

Enter gallons used: 10

MPG this trip: 20.000000

Total MPG: 21.173913

Enter the miles driven (-1 to quit): 120

Enter gallons used: 5

MPG this trip: 24.000000

Total MPG: 21.678571

Enter the miles used (-1 to quit): -1

Overview

For this program, add code to program 2 that will (potentially) allow for a discount to be applied to the cost of the tickets to the movie theater.

Basic Program Logic

The program should start the same as program 2 by asking the user for the number of tickets to purchase for adult and children.

The program should then ask the user if they have a discount coupon. This is a string value. A value of "Y" indicates the user does have a coupon. Any other value indicates the user does not have a coupon.

If the user does have a discount coupon, ask if the coupon is for a free adult ticket or free child ticket. This is also a string value. A value of "A" is for a free adult ticket which means that a discount of 11.25 should be applied to total purchase. A value of "C" is for a free child ticket which means that a discount of 4.50 should be applied to the total purchase. Any other value is invalid which means that no discount should be applied to the total purchase. If an invalid discount type is selected, display a message to the user that their discount type is not valid and that no discount will be applied.

Calculate the user's total purchase amount, making sure to apply the appropriate discount amount (11.25, 4.50, or 0.00).

Finally, display the results similar to program 2: the number of adult tickets that were purchased, the number of child tickets that were purchased, the discount amount (if a discount was applied to the purchase), and the total purchase amount. The discount amount should ONLY be displayed if the user indicated they had a discount coupon. As with program 2, use setw to line up the last digit of the displayed values and setprecision to display 2 digits after the decimal point.

Program Requirements

1. At the top of the C++ source code, include a documentation box that resembles the one from programs 1 and 2.

2. The dollar amounts should all be displayed with exactly 2 digits after the decimal point, including zeros.

3. The numeric values read in from the user should all be integer values. The discount values read in from the user should all be string values. Use meaningful variable names.

4. Make sure and test the program with values other than those in the sample output.

Output

A few runs of the program should produce the following results:

Run 1

Enter the number of adult tickets that are being purchased: 2
Enter the number of child tickets that are being purchased: 5

Design and implement a class called circle_location to keep track of the position of a single point that travels around a circle. An object of this class records the position of the point as an angle, measured in a clockwise direction from the top of the circle. Include these public member functions:
• A default constructor to place the point at the top of the circle.
• Another constructor to place the point at a specified position.
• A function to move the point a specified number of degrees around the circle. Use a positive argument to move clockwise, and a negative argument to move counterclockwise.
• A function to return the current position of the point, in degrees, measured clockwise from the top of the circle. Your solution should include a separate header file, implementation file,
and an example of a main program using the new class.

Write a program in C that takes as input a four-digit hexadecimal number and prints the next

10 hexadecimal numbers. Define a hexadecimal number as

int hexNum[4]

Allow upper- or lowercase letters for input and use uppercase letters for the hexadecimal

output. For example, 3C6f should be valid input and should produce output 3C6F, 3C70,

3C71, . . . .

Write a program in C that takes as input an 8-bit binary number and prints the next 10 binary

numbers. Define a binary number as

int binNum[8];

Use binNum[0] to store the most significant (i.e., leftmost) bit and binNum[7] to store the least

significant bit. Ask the user to input the first binary number with each bit separated by at

least one space.
