- Can you write in C++arrow_forwardWrite a C++ program that takes input for the monthly electricity consumption of a household and calculates the total cost. The user should be able to input the consumption in either kilowatt-hours (kWh) or megajoules (MJ). The program should follow these specifications: Begin by asking the user to choose the energy unit, either kWh or MJ (use switch). Request the user to input the monthly consumption for each day, and store these values in an array. Calculate the total monthly consumption and then determine the total cost based on the following rates: $0.12 per kWh $0.08 per MJ Display the calculated total cost to the user in both dollars and euros. Additionally, provide a message indicating whether the consumption is low, moderate, or high, based on the following criteria: Below 100 kWh or 50 MJ: Low consumption 100 kWh to 300 kWh or 50 MJ to 150 MJ: Moderate consumption Above 300 kWh or 150 MJ: High consumption End the program with an interesting message related to energy…arrow_forwardwrite a C++program that finds the total amount to be spent on a vacation. In Main ask the user for the number of days for the trip and the name of the person booking the trip. It should then call FindHotelCost() and pass both of these variables to that function. The FindHotelCost() function should give a message using the persons name who is booking the trip with the hotel bill. The bill will be 550 dollars for each day of the trip. It should then call AddRentalCar() and pass the name and number of days and the hotel bill to that function AddRentalCar() asks the user for the number of miles that were driven on the rental car and calculates the price of the car. It is $50 per day and .08 cents per mile driven. Show this charge to the user and then add it to the hotel bill for the total bill for the stay. Show this total to the user as well with the person’s name booking the trip.arrow_forward
- write a C++ program that prompts the user to get the number of days to stay at the hotel and to choose a price per night from a list of prices provided in the prompt. your program is to calculate the total charges for the duration stayed at the hotel as follow tax rate should be used as a constant 8% your program should display the following: Customer name, number of days, cost per day, taxes paid and total charges sample input: Customer Name: xxxxxxxxxxxx number of days: xx cost per night (100, 125, 150, 200): xx Sample output Type any hotel name here Customer Name: Number of days Cost per day ---------------------- --------------------- ---------------- John xx xxx Tax Amount: xxx Total Charges: xxx Thank you for staying at "hotel name"arrow_forwardWrite a complete C++ program that prints the change in population of the the United States: p = p + Bp Dp where p is the population, B is the birth rate of 12.4 births for every 1000 people (12.4/1000) each year, and D is the death rate of 8.4 for every 1000 people (8.4/1000). In 2017, the population of United States was 325.7 million. Your program should ask the user for the number of years and print expected population over those years starting from 2017. Each line should have: the year and the population (in millions). A sample run: Please enter the number of years: 10 Year 2017 325.70 Year 2018 327.00 Year 2019 328.31 Year 2020 329.62 Year 2021 330.94 Year 2022 332.27 Year 2023 333.60 Year 2024 334.93 Year 2025 336.27 Year 2026 337.61arrow_forwardWrite a C++ program that takes a number from user and display the output as shown in below two runs of the program.arrow_forward
