1.C is a structured programming language while C++ is an
object programming language .
2.c++ support operator overloading but c doesn't support
operator overloading
3. C employs top down approach, but c++ employes buttom up
approach.
4.C give emphasis in algorithims and functions, but C++
give emphasis on the data and objects.
5.In C we are using #include<stdio.h> as header file, but
in C++ we are using #include<iostream.h> as header file.
6.In C memory allocation is done with malloc statement
whereas in C++ it is done through new keyword.Also memory
is deallocated in C using free statement while in C++
deallocation takes place through delete.
7. *Inline functions are not available in C.
8.The I/O functions are entirely different in C and C++
(ex: printf( ), scanf( ) etc. are part of the C language).
9.Structures in C cannot have functions
10.You cannot overload a function in C (i.e. you cannot
have 2 functions with the same name in C).
11.C does not have reference variables (in C++
referencevariables are used in functions).
12.In other worlds C is used more with hardware while C++
is used more with software, mainly because of more
abstraction and features in C++.
13.You have to include the struct keyword before the name
of the struct type to declare a struct: In C++, you could
do this, and have a new instance of a_struct called
struct_instance. In C, however, we have to include the
struct keyword when declaring struct_instance
14.C++ has a much larger library than C, and some things
may be automatically linked in by C++ when they are not
with C.

class CTest { public: void someMethod() { int nCount = 0; cout << "This is some method --> " << nCount; } }; int main() { CTest *pctest; pctest->someMethod(); return 0; } It will executes the someMethod() and displays the value too. how is it possible with our creating memory for the class . i think iam not creating object for the class. Thanks in Advance... Prakash

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 For this operation, you need to output “Transaction successful” if the intended amount of money can be withdrawn, otherwise output “Transaction unsuccessful” and no money will be withdrawn from his/her account.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
