[what's the difference between the two?]


1. They are just different and not even very similar.
2. Polymorphism is dynamic, that is, the exact function is determined at
runtime, when overloading is static and the exact function is determined
at compile time.
3. In polymorphic mechanism, member function is chosen by the type of 'this'
object, when in overloading the [member] function is chosen by the type of
parameters.
4. Overloading is just aliasing of different functions by one name.
