//*********EXERCISE ODF INHERITANCE***********

//  Create two classes :
// 1. SimmpleCalculator- Takes input of 2 number using a utility function and perfoms +,-,*,/
// and displays the result using another function
// 2. ScientificCalculator - Takes input of 2 numbers using a utility functionand performs any four scientific operations
// of your choice and displays the results using another functions

// create a class hybridcalculator and inhherit it usinng these 2 classes:
// Q1. What type of inheritance you are using ?--> Multiple
// Q2. Which mode of inheritance are you using?--> public
// Q3. Create an object of hybridcalculator and displaybresults of simple and scientific calculator.
// Q4. How is code reusibility implemented?*/
