Class is template for creating similar type of entities.
Class doesn't take memory space untill it contains static
members.
In a specific Class, you declare the attributes(field
variables) and its behaviour(functions).
But Class doesn't have any state and identity.

Objects are the real time entity which are created through
their template, thier class.
By real time entity, I mean they would occupy a memory
space in which they will save the values of its atrributes.
These values create a state of an object.
Since Object occupy a space in memory so they have unique
address in memory. This become the identity of an object.

For example : Pen is a class, which has weight and color as
its attribute. They may have behaviour like write().

Still they don't occupy a space in memory.

When I say My pen ,It will be an object of class Pen since
it will have some values for weight like 10 gm and color
like blue. This will occupy some memory to save these
values.

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
