The Three OOP Principles
All object-oriented programming languages provide mechanisms that help you implement
the object-oriented model. They are encapsulation, inheritance, and polymorphism.
Let’s take a look at these concepts now.
Encapsulation
Encapsulation is the mechanism that binds together code and the data it manipulates,
and keeps both safe from outside interference and misuse. One way to think about
encapsulation is as a protective wrapper that prevents the code and data from being
arbitrarily accessed by other code defined outside the wrapper. Access to the code
and data inside the wrapper is tightly controlled through a well-defined interface.The power of encapsulated code is that everyone knows how to access it and thus
can use it regardless of the implementation details—and without fear of unexpected
side effects.
Inheritance
Inheritance is the process by which one object acquires the properties of another object.
This is important because it supports the concept of hierarchical classification. As
mentioned earlier, most knowledge is made manageable by hierarchical (that is, top-down)
classifications.However, by use of inheritance, an object need only define those qualities that make it
unique within its class. It can inherit its general attributes from its parent. Thus, it is the
inheritance mechanism that makes it possible for one object to be a specific instance of
a more general case.
Polymorphism
Polymorphism (from the Greek, meaning “many forms”) is a feature that allows one
interface to be used for a general class of actions. The specific action is determined by
the exact nature of the situation.
the concept of polymorphism is often expressed by the phrase “one
interface, multiple methods.” This means that it is possible to design a generic interface
to a group of related activities. This helps reduce complexity by allowing the same
interface to be used to specify a general class of action. It is the compiler’s job to select the
specific action (that is, method) as it applies to each situation. You, the programmer, do
not need to make this selection manually. You need only remember and utilize the
general interface.

Objective The objective of this problem is to test the understanding of Object-Oriented Programming (OOP) concepts, in particular, on encapsulation. Problem Description Create a program for managing customer’s bank accounts. A bank customer can do the following operations: 1. Create a new bank account with an initial balance. 2. Deposit money into his/her account. 3. Withdraw money from his/her account. For this operation, you need to output “Transaction successful” if the intended amount of money can be withdrawn, otherwise output “Transaction unsuccessful” and no money will be withdrawn from his/her account. Input The input contains several operations and is terminated by “0”. The operations will be “Create name amount”, “Deposit name amount”, or “Withdraw name amount”, where name is the customer’s name and amount is an integer indicating the amount of money. There will be at most 100 bank accounts and they are all created on the first month when the bank is opening. You may assume that all account holders have unique names and the names consist of only a single word. Output The output contains the transaction result of withdrawal operations and the final balance of all customers after some withdrawal and deposit operations (same order as the input). Sample Input Create Billy 2500 Create Charlie 1000 Create John 100 Withdraw Charlie 500 Deposit John 899 Withdraw Charlie 1000 0
