![Put the class definition in EV.h and the implementation of the constructors and functions in EV.cpp
1. Define a class called "EV", that represents the information of an electric vehicle. The EV is defined with these
attributes: model (string), range(int), unit (string) and year (int). Functions of the EV class must perform
the following operations:
1. A default constructor which sets all the numeric instance variables to zero.
2. A constructor with 4 parameters which sets the 4 instance variables to the corresponding values passed.
3. Implement a getter function for each of the 4 instance variables that will return the value of the instance
variable. For example, the getX() function for the instance variable model must be called
getModel().
4. Implement a setter function for each instance variable that will assign to the instance variable to the
value passed. For example, the setX() function for the instance variable model must be called
setModel().
5. An info function: this function print information of object as following format:
"EV"+ (model]+ "manufactured in" + [year] + "has a range of+[range]+[unit]
6. A Convert function: This function converts the range from kilometers to miles and from miles
to kilometers and returns the result. If the user enters "miles" for the unit and the range in
kilometers, then this function must return the miles. As same if user enters "miles for the unit and
the range in miles, it must return the kilometer value. Using the two equations below:
miles kilometers 1.609
kilometers miles
0.6214
Equation 1
Equation 2
7. A Compare function: This function has one input parameter which is a pointer to an EV object and
prints a message according to following criteria:
If the range of first object (the object that the Compare function is called from) is greater than
second object (input parameter in Compore, the program prints:
info of first object (using info function) new line "drives longer distance on a single charge
than+new lineprint info of second object.
of the range of first object is less than second object, the program prints:
info of first object (using info function) new line "drives shorter distance on a single charge

of the range of first object is equal to second object, the program prints:
