Answer Posted / ketan mehta
The followings are referred as the oops concepts:
Encapsulation:
wrapping up of data and member function
together into a single unit class.
Abstraction:
Showing essential feature without background
detail. Which leads to data security from unauthorized user.
Inheritance:
The property of one class inherited property
of other class. That means object of a child class need to
define only those properties that make it unique within its
class.
Polymorphism:
It is a feature that allows one entity to have
multiple forms.Polymorphism can be achived by Operator
overloading and Function overloading.

i=20;k=0;
for(j=1;k-i;k+=j<10?4:3)
{
cout< What is difference between inheritance and polymorphism? What are the 3 principles of oop? What is coupling in oops? Can we define a class within the interface? 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...
