PROGRAMS ARE DECOMPOSED INTO OBJECTS
INTO FUNCTIONS
allocation is done NEW OPERATOR
with malloc statement
UNOINS AND ENUMS AVALIABLE

c is an object based language where as c++ is an object
oriendted languague. c doesnot supports oops concept,c++
supports oops.
in c there is no cocept of operator overloading, where as
it is in c++.

while these are features of c++.Moreover emphasis are doing
on procedures in c while in c++ emphasis is dealing in

Answer / vaijayanthimala
c is a procedure oriented language and give importants to
procedure that is fuction rather than data.c is a middle
level language.
c++ is a object oriented language and give importants to
object that is data.c++ is high level language.
c does not provide class / object concept
c++ provides encapsulation ,data abstraction,polymorphism..
In c passing a value to a function is "call by value "
where c++ its " call by reference".
c is top to bottom programming approch.
c++ is bottom to top programmong approach.

1)C is procedure oriented language whereas c++ is object

when we want to use them.
4)There is no concept of operator overloading in c whereas
there is a concept of operator overloading in c++.

Base class has two public data members. How can i derive a new class with one datamember as public and another data member as private?.
There are two base class B1,B2 and there is one class D which is derived from both classes, Explain the flow of calling constructors and destructors when an object of derived class is instantiated.
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.

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
