AssignmentWrite a program that calculates the revenue of a trip of a train composed of several train-cars. For the train, the user will give the total allowed train-car count (int), total allowed weight (double), and base speed (double).Then, the user will give train-car information for ALL train-cars that will TRY TO BE ADDED to the train. First, the number of train-cars will be given(int). For each train-car, three information will be given: type of the cargo (std:string), weight of the train-car (double), and how full the train-car is(int).After getting all this information, the program will TRY TO ADD each train-car to the train according to the train-car count and total allowed weightvalues. You CANNOT ADD a train-car to a train if it exceeds its train-car count. You CANNOT ADD a train-car to a train if by adding this train-car, thetotal weight of the train exceeds the train's total allowed weight. Each added train-car reduces the speed of the train by half its weight.Finally, the program will get a distance (int) and a deadline (double) value, calculate the revenue of this trip and prints it out to the screen. Therevenue of a trip is the summation of the revenues of each train-car ADDED to the train affected by the deadline. If the duration of the trip is longerthan the deadline there will be a 40% penalty.Requirements:• You should define and use a class for the train.• You should define a class for train-car and use it for each train-car.• All train related information should be kept as private inside the class.• All train-car related information should be kept as private inside the class.• Classes should take the related input in their constructor functions.• Adding a train-car to the train should be done in a function of the appropriate class with error messages for the two error cases asexplained above with the following error messages:o Exceeding total train-car count: Cannot add car, car capacity is reached.o Exceeding total allowed weight: Cannot add car, total allowed weight is reached.Calculating the total revenue of the train should be done in a function of the train class.• Calculating the revenue of each train-car should be done in a function of the train-car class.Getting all the user input, instantiating objects, adding train-cars to the train, and calling the revenue calculation function of the trainclass should be done in the main() function.NOTE: The type of each train-car can either be "metal", "meat", or "dairy".NOTE: The fullness of a train-car can only be between 0- 100 (including limits).NOTE: The revenue of a train-car is calculated based on the type of the cargo as below: TE: The revenue ol a trdin-car is caIculated based on the type of the cargo as below:• "metal" train-car: 3.5*fullness• "meat" train-car: 8.14*fullness"dairy" train-car: 2.68*fullness3 300 1001 50 872 12 1013metal 10 30meat 8 100Inputmetal 2 50dairy 40 70dairy 3 95meat 40 20meat 80 100dairy 12 8460 1280 3.2100 5.65Cannot add car, carCannot add car,weight capacitycapacity is reachedOutputreached1106.6Cannot add car, car175capacity is reached814Answer assignment
