Answer Posted / george ananth
Overloading(Early Binding):
-> having more than one method with the same name but different signature(argument type, return type, no of argument etc)
-> Compile time Polymorphism because in the compile time system required to find which method is called
Overriding(Late Binding):
-> If the function of base class is redefined in in the derived class is called overriding..The method name and signature of the base class must be same in the derived class (this is done using "virtual and override keyword or new keyword)
-> Run time Polymorphism because system doesn't know which method need to invoke at the compile time..
