Answer / jayasrinivas.donavalli
class:class is an abstract data type in which both Member
functions and member variable are declared that means
aclass is userdefined data type in which we will be able to
declare both methods and variable.
object : Object is an Instance of the class.The class is a
valid one when object is created.
For one class we will have more number of Objects.
declaration of class in
class classname
{
public:
Member variables;
Member functions();
protected:
Member variables;
Member functions();
Private:
Member variables;
Member functions();
};
Declaration of Objects:
class classname allaisname;
here allias name is nothing but objectname.
if we want to get the data from that particular we have to
use objects.
objectname.functionname();

it is one of the object created for that
particular class.

Answer / sanjith
Actually,
*Class is a collection of general declarations for data members and member functions ,that means it doesnot hold any memory.
*when we give certain values to a class ,objects are created.
that means a memory is allocated when objects are created.

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
