Make sure you write code for the three separate files: "SimpleCalculator.h", "SimpleCalculator.cpp", and "lab5.cpp"

Code is in C++ Create a class definition Define member functions Write a test driver to demonstrate the capabilities of a class Task Write a SimpleCalculator class that has public methods for adding, subtracting, multiplying and dividing two doubles. A sample call is as follows double answer= sc.add( a, b ); Object sc is of type SimpleCalculator. Member function add returns the result of adding its two arguments. Below is a sample output (with input shown here in red) The value of a is: 10 The value of b is: 20 Adding a and b yields 30 Subtracting b from a yields -10 Multiplying a by b yields 200 Dividing a by b yields 0.5 Separate your class definition from implementation. Your class definition must be stored in a file called "SimpleCalculator.h". Your class implementation must be stored in a file called "SimpleCalculator.cpp". You also need to provide your own test driver "lab5.cpp" to test all capabilities (i.e. adding, subtracting, multiplying and dividing two doubles) of your SimpleCalculator class
