Prototype is creational design pattern similar to abstract
factory pattern.
Most of you know abstract factory pattern, in the prototype
pattern when you want to create a clone of an object of some
class, then instead of creating directly the clone that
means using new operator and step by step copying the
elements, or you will be calling the copy constructor of the
class.
But in the real time applications we dont want the copy
constructor to be called so it is made as private, and hence
you cannot copy the items, so this design patterns says that
if you want to create the clone of a class, keep the clone
fucntion as virtual in the base class and let the derived
class implement...this is one aspect.

What do you mean by inline function?
What is polymorphism in oops with example?
char* ptr = "Rahul"; *ptr++; printf("%s",ptr); What will be the output
class CTest { public: void someMethod() { int nCount = 0; cout << "This is some method --> " << nCount; } }; int main() { CTest *pctest; pctest->someMethod(); return 0; } It will executes the someMethod() and displays the value too. how is it possible with our creating memory for the class . i think iam not creating object for the class. Thanks in Advance... Prakash
