1. Private and public
2. Delcaring members i.e. data or functions as a private
will not allow them outside the class and calling
themselves through another member of class is data hiding
and encapsulation
3. if class member is declared as public one then it is
accesible outsile the class. And thorugh its object we can
access public members and through them private members.
4. By default the class data members are private
5. It has bottom up approach
Data is hidden
Inheritance is used for reusability concept
polymorphism

#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 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
