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
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
4.overloading must have different method signatures where
as overriding must have same signature.
The main difference between overloading and overriding is
that in overloading we can use same function name with
different parameters for multiple times for different tasks
with on a class.
and overriding means we can use same name fiunction name
with same parameters of the base class in the derived class.
this is also called as reusability of code in the programme.
* in overloading function name are same but signatures
(argument) are different .
while in overriding function name are as well as argument
are same in drive class as in super class.
* for overloading can be done in one class but
for overriding there is necessary that at least two class
should be present.
Overloading - Two or more functions having same name but
different siganture(i.e arguements or return types) for eg.
we have a function named as area then
area();,float area();,area(float a,float b);,float area
(float a,float b);
Overriding - When a function of base class is re-defined in
the derived class.for eg.
area(float a,float b);
. . .
Referring to the sample code above, which one of the
following lines of code produces a written description of
the type of exception that "e" refers to?
a) cout << e.type();
b) cout << e.name();
c) cout << typeid(e).name();
d) cout << e.what();
e) cout << e;
