Write a program that computes and displays the charges for a patient’s hospital stay. First, the program should ask if the patient was admitted as an in-patient or an out-patient. If the patient was an in-patient the following data should be entered: • The number of days spent in the hospital• The daily rate• Charges for hospital services (lab tests, etc.)• Hospital medication charges.If the patient was an out-patient the following data should be entered:• Charges for hospital services (lab tests, etc.)• Hospital medication charges.Use a single, separate function to validate that no input is less than zero. If it is, it should be re-entered before being returned.Once the required data has been input and validated, the program should use two overloaded functions to calculate the total charges. One of the functions should accept arguments for the in-patient data, while the other function accepts arguments for out- patient data. Both functions should return the total charges.
A mobile phone service has three different data plans for its customers: PLAN A: For $19.99 per month, 2 gigabytes are provided. Additional usage costs $8.00 per gigabyte. PLAN B: For $59.99 per month, 8 gigabytes are provided. Additional usage costs $8.00 per gigabyte. PLAN C: For $79.99 per month, Unlimited data is provided. Write a program that calculates a customer’s monthly bill. It should input the customer name, which plan was purchased, and how many gigabytes were used. It should then create a bill that includes the input information and the total amount due. It should also display how much money plan A customers would save if they purchased plan B or C, and how much money plan B customers would save if they purchased plan C. If there would be no savings, no message should be printed. Wherever possible, use named constants instead of numbers.
You are working for a lumber company, and your employer would like a program that calculates the cost of lumber for an order. The company sells pine, fir, cedar, maple, and oak lumber. Lumber is priced by board feet. One board foot equals one square foot that is one inch thick. The price per board foot is given in the following table: The lumber is sold in different dimensions (specified in inches of width and height, and feet of length) that need to be converted to board feet. For example, a 2 x 4 x 8 piece is 2 inches wide, 4 inches high, and 8 feet long, and is equivalent to 5.333 board feet (2 * 4 * 8 = 64, which when divided by 12 = 5.333 board feet). An entry from the user will be in the form of a letter and four integer numbers. The integers are the number of pieces, width, height, and length. The letter will be one of P, F, C, M, O (corresponding to the five kinds of wood) or T, meaning total. When the letter is T, there are no integers following it on the line. The program…

7) The ideal gas law allows the calculation of volume of a gas given the pressure(P), amount ofthe gas (n), and the temperature (T). The equation is:V = nRT / PSince we only have used integer arithmetic, all numbers will be integer values with nodecimal points. The constant R is 8.314 and will be specified as (8314/1000). This givesthe same result. Implement the idea gas law program where the user is prompted for andenters values for n, T, and P, and V is calculated and printed out. Be careful toimplement an accurate version of this program. Your program should include a properand useful prompt for input, and print the results in a meaningful manner

Example: Enter the price of the first article: 200Enter the price of the second article: 50Enter the price of the third article: 25Discount: 30.00Total: 245.00 Put your program in electronics.py
3) Suppose an airline company has hired you to write a program for choosing the passengers who should leave an overbooked flight. That means the airline has booked too many passengers hoping some of them would not show up on time, but passengers are on board and the aircraft doesn't have enough seats available for all these passengers. Your program chooses the passenger who must leave the flight. Passengers will be ranked based on the fare they have paid for booking (a double number called fare), and their number of loyalty points (an integer number called points). Fare and points are equally important, that means, in order to decide the position of each passenger in the list, fare and points each have 50% importance. A Person with minimum priority (combination of fare and points) will leave the flight. You need to define a class called Passenger with these member variables: passenger's name • fare points. Passenger class must have 3 accessors, 3 mutators, a constructor with three…
Write a program that computes and displays the charges for a patient's hospital stay. First, the program should ask if the patient was admitted as an inpatient or an outpatient. If the patient was an inpatient, the following data should be entered: • The number of days spent in the hospital • The daily rate Hospital medication charges • Charges for hospital services (lab tests, etc.) The program should ask for the following data if the patient was an outpatient: • Charges for hospital services (lab tests, etc.) • Hospital medication charges The program should use two overloaded functions to calculate the total charges. One of the functions should accept arguments for the inpatient data, while the other function accepts arguments for outpatient information. Both functions should return the total charges and display it for the user. After the total charges have been calculated and displayed, write the result to a file, PatientReport.txt. You can use the techniques you learned in Chapter…
Problem 7: Guess the price of the car!? You will implement a variant of the number guessing game we played in lecture. In this variant, you will ask the user to guess the price of a $42,500 car. Let's assume that the player knows the price of the car is rounded to the nearest $500. If a player's guess is not exactly correct, your program will tell them they are either too high or too low. The player will get as many guesses as they need to guess the price of the $42,500 car. However they will only win the game if they used 5 or fewer guesses. Here are two examples of how the program should work for both cases: Guess the price and win the prize! Enter your guess:50000 Too high! Enter your guess:40000 Too low! Enter your guess:45000 Too high! Enter your guess:42500 You won the car! Guess the price and win the prize! Enter your guess:46000 Too high! Enter your guess:45000 Too high! Enter your guess:44000 Too high! Enter your guess:43000 Too high! Enter your guess:42000 Too low! Enter your…
