- Write a program that asks the user to enter a month (1 for January, 2 for February, etc.) and thenprints the number of days in the month. For February, print “28 days”.Enter a month: 530 daysarrow_forwardWrite a program that reads the amount of a monthly mortgage payment andthe amount still owed—the outstanding balance—and then displays theamount of the payment that goes to interest and the amount that goes toprincipal (i.e., the amount that goes to reducing the debt). Assume that theannual interest rate is 7.49 percent. Use a named constant for the interest rate.Note that payments are made monthly, so the interest is only one twelfth ofthe annual interest of 7.49 percent.arrow_forwardWrite a program that calculates the electricity bill. The rates of electricity per unit are as follows:If the units consumed are <=300, then the cost is Rs. 12 per unit.If the units consumed are >300 and <=500, then the cost is Rs. 17 per unit. If the units consumed exceed 500 then the cost per unit is Rs. 22A line rent of Rs. 1500 is also added to the total bill and surcharges of 5% extra if the bill exceeds Rs. 15000. Calculate the total bill with all the conditions given above.arrow_forward
- Write a program that asks the user to enter a number of seconds.Solving the Time Calculator ProblemThere are 86400 seconds in a day. If the number of secondsentered by the user is greater than or equal to 86400, thethe program should display the number of days in that manyseconds.There are 3600 seconds in an hour. If the number of secondsentered by the user is less than 86400 but is greater than orequal to 3600, the program should display the number of hoursin that many seconds.There are 60 seconds in a minute. If the number of secondsentered by the user is less than 3600 but is greater than or equalto 60, the program should display the number of minutes in thatmany secondsarrow_forwardWrite a code using C++ for the given prompt: A contractor orders, say, 30 cubic yards of premixed concrete to construct a patio that is to be, say, four inches thick. The length of the patio is to be, say, twice the width. Write a program that prompts the user to specify: The amount of premixed concrete (in cubic yards) ordered The thickness of the patio (in inches) The ratio of length and width Ex. If the ratio is 3 to 2, have the program accept a 3 then a 2. Then compute the ratio using these numbers The program then outputs: The length and width of the patio (in feet). (1 cubic yard = 27 cubic feet.) To calculate the width, you will need to: Find the total cubic feet of the concrete Divide the total cubic feet of concrete by the result of the length to width ratio multiplied by the thickness of the patio, over 12 (inches in a foot) Square root the answer To find the square root of a decimal number, include the header file cmath using the statement #include <cmath>,…arrow_forwardWrite a program that computes the amount of calories burned when you run. Your program should ask for the duration of the run in minutes the speed of the run in mph and your weight in pounds. Compute the amount of calories burned and print it. The calories burned is computed using the expression below: \n", "\n", "$$ calories/minute = (MET*weight*1.6)/200 $$\n", "\n", "MET is a value given below:\n", " - if speed is 5mph or less - MET = 8\n", "- if speed is greater than 5 and less or equal 8 mph - MET = 11.5 \n", "- if speed is greater than 8 and less or equal 10 mph - MET = 14 \n", "- if speed is greater than 10 mph - MET = 20\n", "\n", "Remeber to multiply this result by the time running to show the total amount of calories burned.\n"arrow_forward

The program outputs the number of miles the automobile can be driven without refueling.arrow_forwardWrite a program that calculates the change due a customer by denomination; that is, how many pennies, nickels, dimes, etc. are needed in change. The input is to be the purchase price and the size of the bill tendered by the customer ($100, $50, $20, $10, $5, $1)arrow_forward
- Write a program that computes the theoretical flame temperature when a mixture of methane, propane, n-butane, and n-pentane (0% to 100& methane in 5% increments; 0 to 100 mol% propane in 5% increments; 0% to 100% mole n-butane in 5% increments) at 25°C is burned with excess air (0% to 100% excess in 5% increments) preheated to preheated to (50°C to 200°C in 10°C increments)arrow_forwardWrite a program for a Bookstore to take an order from a customer, calculate how much to charge a customer based on his/her order, and display a receipt. The store sells only three books, designated by their authors: Cervantes ($41.25 each), Homer ($15.85 each), and Shakespeare ($30.50 each). Your program is to work as follows: Display a welcome message (e.g., “Welcome to the Bookstore!”) Prompt the user for his/her first name Prompt the user to input the number of books by Cervantes s/he wants Prompt the user to input the number of books by Homer s/he wants Prompt the user to input the number of books by Shakespeare s/he wants Compute the total amount due, including a 10% sales tax Display amount due Ask the user how much money s/he will pay Display a receipt listing the name of the user, the quantity of each item ordered, the total cost of the order, and the amount the user will have left after paying Execution of the compiled program should appear roughly as follows (with red…arrow_forwardWrite a program that can be used to calculate the federal tax. The tax is calculated as follows: For single people, the standard exemption is $4,000; for married people, the standard exemption is $7,000. A person can also put up to 6% of his or her gross income in a pension plan. The tax rates are as follows: If the taxable income is: Between $0 and $15,000, the tax rate is 15%. Between $15,001 and $40,000, the tax is $2,250 plus 25% of the taxable income over $15,000. Over $40,000, the tax is $8,460 plus 35% of the taxable income over $40,000. Prompt the user to enter the following information: Marital status If the marital status is “married,” ask for the number of children under the age of 14 Gross salary (If the marital status is “married” and both spouses have income, enter the combined salary.) Percentage of gross income contributed to a pension fund Your program must consist of at least the following functions: Function getData: This function asks the user to enter the…arrow_forward
