Write a simple calculator program. Your program should accept as input an expression in the form of: 3 * 2 Use an if / elif ladder style structure to determine what operation needs to be performed on the two numbers. Your program should handle the arithmetic functions Add, Subtract, Multiply, and Divide (Depending on the operator entered). Input: For this assignment you are going to want to take in a string that has the expression separated by a space. Once you have stored the string you will need to split it. This means to get each individual part of the expression. Python has a split function that is part of the string. It will return a list of the pieces that were split. I realize we haven't discussed lists yet so I will give you some code. Suppose you have the expression: str

Write a car class having two private member variables called tank and speed. write public methods called pumpgas and gofast. the method pumpgas gets an integer for gas that must be pumped. that value needs to be added to tank (no more than 20 gallons). it must return the amount of gas that is purchased ($4 per gallon). the method gofast should increase the speed by 5 each time it is called.write a constructor for the above class that initialized both variables to zero.write a tostring to display both the tank and speed when the car is printed.modify the car class to implement the interface comparable and an interface called carinter having the public methods in carinter.write the main program to create an array of size 5 of type car. create 5 car objects having each location of the array to refer to one of the cars. test the pumpgas, gofast, equals method on the array items. write an enhanced loop to print all the car values (using a tostring written last time).write a generic method to find the minimum of four items. pass int, double, char, string and car objects to test this method.
