I need to use a loop for the program and the include statement's that we've learned so far is #include iostream, string, limits, cmath. The professor said we would be using commands if(cin.fail()){

cin.clear();

cin.ignore(numeric_limits::max());

}

You will be creating a program that calculates a fleet's car and truck miles per gallon.

Create a program that continually asks for a command, which will be "car", "truck", or "done". If the user does not specify one of these commands, output "Unknown command."

If the user types "done", calculate the average miles per gallon of all of the given cars and calculate the average miles per gallon of all of the given trucks. If the user did not provide any cars, output "Fleet has no cars." If the user did not provide any trucks, output "Fleet has no trucks." Otherwise, output "Average car MPG = " and "Average truck MPG = ".

If the user types "truck" or "car", then ask the user for the number of miles and number of gallons of fuel used on either the truck or car. This will be a running total. You will need to store the total number of miles, total number of gallons, and total number of cars and trucks.

You must also make a check to ensure the user gives you proper input. If improper input was given, keep asking the user to give you legitimate values until they comply (see examples below).

./lab4 Enter command: car Enter car's miles: 255 Enter car's gallons: 13 Enter command: car Enter car's miles: 715 Enter car's gallons: 33 Enter command: truck Enter truck's miles: 477 Enter truck's gallons: 22 Enter command: done Average car MPG = 21.087 Average truck MPG = 21.6818

./lab4 Enter command: done Fleet has no cars. Fleet has no trucks.

./lab4 Enter command: car Enter car's miles: 177.25 Enter car's gallons: 22.182 Enter command: done Average car MPG = 7.99071 Fleet has no trucks.

./lab4 Enter command: car Enter car's miles: z Enter car's miles: k Enter car's miles: l Enter car's miles: m Enter car's miles: n Enter car's miles: 18.2 Enter car's gallons: p Enter car's gallons: n Enter car's gallons: o Enter car's gallons: l Enter car's gallons: z Enter car's gallons: 22.15 Enter command: ca Unknown command. Enter command: d Unknown command. Enter command: done Average car MPG = 0.82167 Fleet has no trucks.
