(This is a better version of an exercise from Chapter 1.) A government research lab has concluded that an artificial sweetener commonly used in diet soda pop causes death in laboratory mice. A friend of yours is desperate to lose weight but cannot give up soda pop. Your friend wants to know how much diet soda pop it is pos- sible to drink without dying as a result. Write a program to supply the answer. The input to the program is the amount of artificial sweetener needed to kill a mouse, the weight of the mouse, and the desired weight of the dieter. Assume that dietsoda contains 1/10th of 1% artificial sweetener. Use a named constant for this fraction. You may want to express the percent as the double value 0.001.

A laborant in a laboratory does a number of antigen tests in one day. Write a program that
simulates the number of antigen tests done in a day in a laboratory, displays the number of
positives and negatives, and calculates the % of positives in one day. Your program needs
to first generate a random number that will show the number of tests done in a day. One
laboratory in a day cannot do more than 100 tests and less than 1 (they do at least one).
Then for each of the tests, your program needs to generate a random number to show
whether they are positive or negative. In order to write this program, you need to have the
following three functions used by the main function:
test result (void): This function generates a test result. It should randomly
return either one or zero. 1 means positive test result and 0 means negative test result.
float positive percentage (int,int) : This function takes the total number of
positives and the total number of tests and returns the % of positives.…
Write a program that calculates the equivalent resistance of a circuit. n electrical resistors with
resistance values R1, R2,.., Rn are said to be connected in parallel if the same voltage is applied
across each. Their equivalent resistance Reg is related to the values R1, R2, ...,
Rn by:

Write a program that prompts the user to enter the resistance of n resistors. The user should
be prompted continuously by using a while loop until a zero or negative value is entered (the
program should count the number of resistors n entered by the user and store the values in an
array). Use another separate loop to print the resistance values entered by the user and the
equivalent resistance Reg. Test your program with R1= 1 kn, R2= 2 kn, R3= 4 kQ and R4= 8 kQ.

- You have been asked to write a program to play rock-paper-scissors. Your program will ask the user to input a number 0, 1, or 2 to denote rock, paper, and scissors respectively. Your program will then randomly generate a number 0, 1, or 2 to denote the computer’s hand. The rules for the game are: •A scissor can cut paper. •A rock can knock a scissor. •A piece of paper can wrap a rock. Let the game run continuously until either the user or the computer wins 3 times, displaying the outcome of each hand. At the end of the game, display a message indicating whether the user or the computer wins Helpful Hint: import random player2= random.randint(0, 2)arrow_forward.

- A parking garage charges a $2.00 minimum fee to park for up to three hours. The garage charges an additional $0.50 per hour for each hour or part thereof in excess of three hours. The maximum charge for any given 24-hour period is $10.00. Assume that no car parks for longer than 24 hours at a time. Write a program that calculates and prints the parking charges for each of three customers who parked their cars in this garage yesterday. You should enter the hours parked for each customer. Your program should print the results in a neat tabular format and should calculate and print the total of yesterday’s receipts. The program should use the function calculateCharges to determine the charge for each customer. Your outputs should appear in the following format Sample output Enter the hours parked for 3 cars: 1.5 4.0 24.0 Car Hours Charge 1 1.5 2.00 2 4.0 2.50 3 24.0 10.00 TOTAL 29.5 14.50arrow_forwardWrite a python program of the following using the modification of the second picturearrow_forwardAn instructor gives a series of exams during the semester in her math class. At the end of the semester she drops each student's lowest test score before averaging the scores. She has asked you to design a program that will read a student's test scores as input and calculate the average with the lowest score dropped. Here is the algorithm that you developed: Get the student's test scores. Calculate the total of the scores. Find the lowest score. Subtract the lowest score from the total. This gives the adjusted total. Divide the adjusted total by 1 less than the number of test scores. This is the adjusted average. Display the average. The test scores are in a text file named scores.txt and contains the following: Mickey, 71.0, 42.0, 83.0 Donald, 94.0, 73.0, 72.0, 81.0 Minnie, 95.0, 85.0, 45.0, 55.0, 65.0 A sample run is as follows: Enter a file containing floating point numbers: scores.txt Test scores for Mickey: ['71.0', '42.0', '83.0'] Removed the lowest score of 42.0 for Mickey The…arrow_forward

This will give you practice with random numbers and loops while allowing you to explore and understand a little more Java code. You will also need to test out this program to ensure the correctness of the algorithm and code. You will need to develop test data that will represent all possible kinds of data that the user may enter. You are going to write a program that allows the user to play a simple guessing game in which your program thinks up an integer between 1 and 100 and allows the user to make guesses until the user gets it right. (The program also counts how many tries it took to get the correct number). For each incorrect guess you will tell the user whether the right answer is higher or lower. Your program is required to exactly reproduce the format and behavior of the log of execution.

- ..arrow_forwardWrite a "Guess My Number Game" program. The program generates a random integer in a specified range, and the user (the player) has to guess the number. The program allows the use to play as many times as he/she would like; at the conclusion of each game, the program asks whether the player wants to play again. The basic algorithm is: 1. The program starts by printing instructions on the screen. 2. For every game: the program generates a new random integer in the range from MIN to MAX. Treat MIN and MAX like constants; start by initializing them to 1 and 100 ► loop to prompt the player for a guess until the player correctly guesses the integer for each guess, the program prints whether the player's guess was too low, too high, or correct at the conclusion (when the integer has been guessed): ➤ print the total number of guesses for that game print a message regarding how well the player did in that game (e.g., the player took way too long to guess the number, the player was awesome,…arrow_forward1. Write a pyrhon program that prints out a classic hangman stick figure. The program should ask the user to enter a number from 1-6 and the corresponding hangman should be printed. The value the user inputs corresponds to the number of incorrect guesses in a real hangman game and so the completeness of the hangman will correspond to the number of ‘incorrect guesses’ inputted by the user (e.g., if the user enters 1, then only the head of the hangman will be printed; full example below). Example:Enter a number from 1-6: 1O Enter a number from 1-6: 2O|Enter a number from 1-6: 3O\||Enter a number from 1-6: 4O\|/|Enter a number from 1-6: 5O\|/|/Enter a number from 1-6: 6O\|/|/ \ 2. Modify your program from problem 1 so that the user input is checked to be a validsingle digit (1-6) before printing the corresponding hangman. If the input is not valid, theninstead of a hangman the following message should be printed “Invalid input: you must enter asingle number from 1-6.” Example:Enter a…arrow_forward
