21. GeeBees Clothiers is having a sale. The store manager wants a program that allows asalesclerk to enter the original price of an item and the discount rate. The programshould calculate and display the amount of the discount and the sale price. Thealgorithm in Figure 2-21 is supposed to solve this problem, but it is not workingcorrectly. Correct the algorithm, and then desk-check it using an original price of $100and a discount rate of .25 (the decimal equivalent of 25%).Output:discountsale priceoviginal prícediscount rateImput:Algorithm:1. enter the original price and discount rate2. calculate the sale price by subtracting the discount from the original price3. display the discount and price

Corrected algorithm: The algorithm calculates the discount by multiplying the original price by…

Chess bishop moves diagonally in any number of squares. Given two different squares of the chessboard, determine whether a bishop can go from the first square to the second one in a single move. The program receives four numbers from 1 to 8 each specifying the column and the row number, first two - for the first square, and the last two - for the second square. The program should output YES if a bishop can go from the first square to the second one in a single move or NO otherwise. Define a function called bishop_move # Example input ```4455``` # Example output ```YES``` #
In programming language C.Write an algorithm to input a number. Find its square if the entered number is multiple of 10. If entered number if not a multiple of 10, then find its cube.
Mad Libs are activities that have a person provide various words, which are then used to complete a short story in unexpected (and hopefully funny) ways. Write a program that takes a string and an integer as input, and outputs a sentence using the input values as shown in the example below. The program repeats until the input string is quit and disregards the integer input that follows. Ex: If the input is: apples 5 shoes 2 quit 0 the output is: Eating 5 apples a day keeps the doctor away. Eating 2 shoes a day keeps the doctor away.
3. The bin packing problem is to pack the objects of various weights into containers. Assume that each container can hold a maximum of 10 pounds. The program uses an algorithm that places an object with the largest weight into the first bin in which it would fit. Your program should prompt the user to enter the total number of objects and the weight of each object. The program displays the total number of containers needed to pack the objects and the contents of each container. Here is a sample run of the program: Enter the number of objects about itinerary with the following members: 1. A data field named flgihts of the List type. The list contains the flights for the itinerary in increasing order of departure Time. A constructor that creat: 6 Enter the weights of the objects: 7 5 2 3 5 8 Container 1 contains objects with weight 8 2 Container 2 contains objects with weight 7 3 Container 3 contains objects with weight 55
Homework write a program that will add the terms of an infinite geometric series. The program should read the first term (a) and the common ratio (r) for the series. It should the compute the sum in two ways: by formula (s=a/1-r), and by adding the individual terms until the answer agrees with the formula to 7 significant digits. The print the formula answer, the answer found by adding terms, and the number of terms that were added. Print the sums to at least ten places. Verify input with a while loop. Two real values are equal to n significant digits if the following condition is true: |a-b|<|a*10^-n| Wrong test - this won't work if r is very near one. Try a=2, r=.99999 With smaller values of r, it is asking for too much precision. With a=2,r=.99, it is getting 10 significant digits. HELP ME FIX CODE.

The program must able to input the customers age then set the conditions so the price is determined as follows: age 0-5 age 6-20 price=15000 1.D (Iraqi dinar) price 25000 ID(Iraqi dinar) price 40000 I.D (Iraqi dinar) age >21
Transient PopulationPopulations are affected by the birth and death rate, as well as the number of people who move in and out each year. The birth rate is the percentage increase of the population due to births and the death rate is the percentage decrease of the population due to deaths. Write a program that displays the size of a population for any number of years. The program should ask for the following data: The starting size of a population P The annual birth rate (as a percentage of the population expressed as a fraction in decimal form)B The annual death rate (as a percentage of the population expressed as a fraction in decimal form)D The average annual number of people who have arrived A The average annual number of people who have moved away M The number of years to display nYears Write a function that calculates the size of the population after a year. To calculate the new population after one year, this function should use the formulaN = P + BP - DP + A - Mwhere N is the…

19. The manager of a video rental store wants a program that calculates the amount a customer owes when he or she returns a video. A customer can return only one video at a time. The rental fee is $3.50 for four days. Customers are charged a late fee (currently, $2) per day when the video is returned after the due date. Study the algorithm and desk-check table shown in Figure 2-19, and then answer the questions. a. What will the algorithm display when the user enters 3 as the number of late days? What will it display when the user enters 0 as the number of late days? b. How would you modify the solution and desk-check table to include the total late charge as a processing item? c. How would you modify the solution from Question b to also display the total late charge? Output: amount due Input: number of late days daily late fee Algorithm: 1. enter the number of Late days and daily late fee 2. calculate the amount due by multiplying the number of Late days by the daily late fee, and…
3. The formula for determining compound interest is: A represents the amount to earn; P is the principle that is initially invested; r is the interest rate earned; n is the number of times the interest is compounded; and t is the number of time periods for the investment. Write a program that prompts the user to enter P, r, n and t. The program should output the amount earned on the investment. 4. Look up the Pythagorean theorem if you are not already familiar with it. Use the following formula to solve for c in the formula: c = √a2 + b2. Use the proper functions from the cmath header file. Be sure to output the result.l
