4. Describe different levels of inheritance with examples.
5. Create a student database using the concept of files. Include the following fields.

Difference between Overloading and over riding

1. In overloading,there is a relation ship between methods
available in the same class where as in overridding,there
is relationship between a super class method and subclass
method.

2. overloading doesn't block inheritence from the
superclass where as overridding blocks inheritence.

3. in overloading,seperate methods share the same name
where as in overridding,subclass methods replaces the
superclass.

4.overloading must have different method signatures where
as overriding must have same signature
