OOPs

In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.

Constructor

The easiest way to think of a constructor in object-oriented programming (OOP) languages is:

Overview Construct a hierarchy of classes representing savings and checking accounts as well as a means to ‘filter’ account objects. Account Classes Your solution will consist of 4 account classes as described below. It is your responsibility to define the exact relationship among those classes and translate that relationship into source code structure. There is a correct structure; the skeleton must be modified to reflect the correct relationships.  Account – represents a general account with basic operations such as deposit, withdraw, etc.  Savings – represents a savings account that must maintain a minimum balance.  Checking – represents a checking account that has no minimum balance (this means a zero balance).  CappedChecking – represents a checking account that disallows a balance above a particular maximum value. Linking Accounts A bank or credit typically allows a user the ability to link accounts together. That is, I might wish to link my checking account with my savings…
