RE: What is the difference between OVERRIDING and OVER...
Overloading is compile time binding, where as overriding is dynamic binding.A good example that differentiates between overloading and overriding is shown here.
RE: What is the difference between OVERRIDING and OVER...
Please clarify the difference class A { void calc() { } int calc(int) { } } class B:public A { void calc() { } }
This is just an abstract of the program. If we have a program like this and an object of class B is created and we call b.calc will the compiler first call the method calc of super class or sub class? What will be the effect of virtual key word on this program? Is the calc function over loaded? Can we say this as an example for over riding?

------------------------------------------------------------------------- In this case, when class B calls a.calc the complier will first look at the signature of calc. Class B needs to either call a.calc() or a.calc(int).
