1. In C++, what is the difference
between method overloading and method
overriding? Overloading a method (or
function) in C++ is the ability for
functions of the same name to be defined
as long as these methods have different
signatures (different set of
parameters). Method overriding is the
ability of the inherited class rewriting
the virtual method of the base class.
2.What methods can be overridden in
Java? In C++ terminology, all public
methods in Java are virtual. Therefore,
all Java methods can be overwritten in
subclasses except those that are
declared final, static, and private.
3. In C, what is the difference between
a static variable and global variable? A
static variable declared outside of any
function is accessible only to all the
functions defined in the same file (as
the static variable). However, a global
variable can be accessed by any function
(including the ones from different
files).
4.In C, why is the void pointer useful?
When would you use it? The void pointer
is useful becuase it is a generic
pointer that any pointer can be cast
into and back again without loss of
information.
5.What are the defining traits of an
object-oriented language? The defining
traits of an object-oriented langauge
are:
-
Encapsulation
-
Inheritance
-
Polymorphism
