 Question Submitted By :: C-Sharp

Answer
# 1
overloding:- if we want to use a function which have
different behaviour in different situation means for
different signature it behaves differently it is called
function overloding
overriding:- if we want a function which have the same
behaviour in the supercalss as well as in the subclass also
and in the case of overriding method signature and return
type should be same , it is called method overriding
boxing:
if we want to convert a value type value in an object it
is called boxing
for example
int m=10;
object om=10;
it does not require any explicitly conversion
unboxing:-unboxing means when we want to convert a object
type to a value type , it is called unboxing
int m=10
object om=m;
byte n=(byte)om;
