An Abstract Class is one in which the member function(s) at
the Base(Parent) Class are left undefined, but declared.
It's upto the Derived(child(ren)) Classes to Implement the
Functions declared in Base...


Ex:

Let us assume... As a father(Base Class), he has some Land
(Member Function), and he has not done any cultivation
(implementation) in it... As his Child(Derived Class), he
takes the Land(Member Function) from the Father(Base) and
does Agriculture(implementing the M.F. of Parent Class) in
the Child...

Concept of Inheritance...

Is it good enough!!!

#include #include #include #include void insert(char *items, int count); int main(void) { char s[255]; printf("Enter a string:"); gets(s); insert(s, strlen(s)); printf("The sorted string is: %s.\n", s); getch(); return 0; } void insert(char *items, int count) { register int a, b; char t; for(a=1; a < count; ++a) { t = items[a]; for(b=a-1; (b >= 0) && (t < items[b]); b--) items[b+1] = items[b]; items[b+1] = t; } } design an algorithm for Insertion Sort

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.

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. Question Submitted By :: Sunil Kumar I also faced this Question!!

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
