What is an interface in oop?
Can we have inheritance without polymorphism?
Why can't we have instance(stack) of a class as a member of the same class like eg.Class A{A obj;} as we can have self refential pointer
Following are the class specifications: class {int a}; class {int b}; Using friend funtion,calculate the max of two objects and display it.
c++ program to swap the objects of two different classes
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

How to handle exception in c++, For example in a functions i am assigning memory to some variables and also in next instructions in am dividing one variable also. If this functions generates a error while allocating memory to those variable and also while dividing the variable if i divide by zero then catch block how it will identify that this error has cone from perticular instruction
