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withdrawn, otherwise output “Transaction unsuccessful” and
no money will be withdrawn from his/her account.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

Question In a class, there is a reference or pointer of an object of another class embedded, and the memory is either allocated or assigned to the new object created for this class. In the constructor, parameters are passed to initialize the data members and the embedded object reference to get inialized. What measures or design change should be advised for proper destruction and avioding memory leaks, getting pointers dangling for the embedded object memory allocation? Please suggest.

Answer # 1 use copy constructors 0 Shanthila There is something to be taken care in destructor, in copy constructor, suppose the memory is assigned to the embedded member object pointer with the parameter passed value, but if some other objects of different class also are pointing to this memory, then if some one deletes the object then this class member pointer object will become dangling, or if the object is not deleted properly then there will be memory leak. Please suggest the design change required to handle or avoid this situation

what is the size of an empty class
Question: Implement a base class Appointment and derived classes Onetime, Daily, Weekly, and Monthly. An appointment has a description (for example, “see the dentist”) and a date and time. Write a virtual function occurs_on(int year, int month, int day) that checks whether the appointment occurs on that date. For example, for a monthly appointment, you must check whether the day of the month matches. Then fill a vector of Appointment* with a mixture of appointments. Have the user enter a date and print out all appointments that happen on that date.
what are the characteristics of oops?
write a code for this:trailer recordId contains a value other than 99, then the file must error with the reason ‘Invalid RECORD_ID’(User Defined Exception).
what is ns string? what is ns array?
Why do we use virtual functions?
String = "C++ is an object oriented programming language.An imp feature of oops is classes and objects".Write a pgm to count the repeated words from this scenario?
what is the difference between class and structure in C++?
What do you mean by variable?
create a class complex having real and imaginary part of a complex no. as a data member. overload the binary operators(+,- and *) to perform the operations on complex no. objects. overload binary operator using friend function.
