Designing module for managing collection of product type data

This solution code should contain definition for product model along with it’s properties. The program should also provide impelementations of CRUD operations for the Product model

This exercise contains project for solution code for Product entity and Product Repository classes

1. Product model class

• This class should provide common properties for the Product model.
• More on properties is provided in boilerplate code

Sample Output 1

410

to solve this approch

if i value is even:

result = summation of the term value and then added to the result

else :

result = Subtraction of the term value and then added to the result

2. Design a class Account that has the following member: Data Fields: account_id(int type), balance(double type)).

Member Functions-> withdraw(),deposit(),getmonthly_interest() and parameterize constructor to initialize data members. Use this class to print the balance. Use the withdraw () to withdraw money less than Rs 5000 and then deposit more than or equal 1500 using deposit function. (6)
