The program contains 3 options, 1st option is for Permutation, 2nd option is Combination and 3rd is for terminating the system. For option 1, Permutation, they uses the following formula: nPr =  ; where r must not be greater than n. It should not proceed if this condition is not met. For 2nd option, Combination, they uses the formula : nCr =  ; where r must not be greater than n as well. For the 3rd option, the program owner’s information shall be displayed, like name, subject code and account number, before the program terminates.  Requirements: Develop the required system and use cpp for the file name Remember that both n and r are variables, their values shall only be entered at run time.

- Modify the program you wrote in Programming Challenge 19 so that it reports the number of pizzas you need to buy for a party if each person attending is expected to eat an average of 4 slices. The program should ask the user for the number of people who will be at the party and for the diameter of the pizzas to be ordered. It should then calculate and display the number of pizzas to purchase. Because it is impossible to buy a part of a pizza, the number of required pizzas should be displayed as a whole number.arrow_forwardQuestion Using Java programming language write a program to manage a hotel with 24 rooms;10 rooms are Executive, with price Gh ₵ 2500.00 per night,7 rooms are Chalets, with amounts Gh ₵ 1500.00 per night7 rooms are Ordinary, with amount Gh ₵ 500.00 per night The program should allow customers to book for rooms for a number of nights, and update the number of empty rooms available for each category when a customer has paid fully and has checked-in; also update the number of empty rooms available when customer checks-out.Customers should make bookings with their first names, telephone number A customer should be prompted to know if a room is booked (meaning a another customer has booked it but has not paid fully, or has not checked-in) A customer should be prompted to know if a room is occupied (meaning a booked room has been fully paid for, or the customer has checked-in) A customer should be prompted to know if a room is available (meaning a room has neither been booked nor…arrow_forwardThis code when ran asks for job code and then hours worked, but when I put in 20 or 40 hours I get an error... indexerror: Tuple index out of range Its supposed to be for up to 40 hours, no more then that.. how do I fix the tuple range? # Name: Erica Strong # Prog Purpose: This program computes employee weekly pay # Category codes: # C Cashier: $16.50 # S Stocker: $15.75 # J Janitor: $15.75 # M Maintenance: $19.50 import datetime # define pay rates & deduction rates PAY_RATES = (16.50, 15.75, 15.75, 19.50) DEDUCTION_RATES = (0.12, 0.03, 0.062, 0.0145) # define global variables inout = 'C' # C means Cashier, S means Stocker, J means Janitor, M means Maintenance hoursworked= 0 payrates = 0 deductionrates = 0 grosspay = 0 netpay = 0 ############ Define program functions ############ def main(): another_employee = True while another_employee: hours_worked, job_code = get_user_data() gross_pay = perform_calculations(hours_worked, job_code) total_deductions, deductions =…arrow_forward
- ASSIGNMENT: 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: Pine 0.89 Fir 1.09 Cedar 2.26 Maple 4.50 Oak 3.10 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, 4inches 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,…arrow_forwardWhat is the value of the expression 10 + t1%t2*5/(t3-1)?

E.g., lottery = 123, input = 123(2) If the user input matches the lottery, but in wrong order, print "the award is $6,000". E.g., lottery = 123, input = 321(3) If two digits in the user input matches a digit in the lottery, print "the award is $3,000". E.g., lottery = 123, input = 612(4) If one digit in the user input matches a digit in the lottery, print "the award is $1,000". E.g., lottery = 123, input = 289(5) If none of the digits is matched, print "thank you".arrow_forward
