Answer / pankaj kumar sharma

Function overloading takes place when a function is
overloaded with two or more tasks ie. same function is
having different behaviour.
It takes place when two functions have same name but
differs in argument list ie. may be the no of arg in both
fun are different or type of the arguments in argument list
are diff.

As return type of a func. does not take part in name
mangling so return type for overloaded functions may differ
or not.

eg: int fun(int arg1, int arg2)
char* fun(char* ptr1)

Answer / rabih

two functions with same but different signature

example let take function name test return int and take a
parameter of type int (int test(int x))

let take same function of name test with different
signature void test(int x) or int test(bool n) or
int test(int x,string y)

all these functions can written in same class without any
error this means same function name(test)
different signature is deffernet return type or different
paraemeter type

Answer / achal ubbott

Here i tell how function overloading works. The point is
name mangling. Each c++ compiler follows an algorithm
called Name Mangling algorithm. Its job is to create
different symbols for functions. The mangled name of the
function would depend upon number,type and order of
function arguments. You can see these mangled names in the
assembly code. But C does not mangle function Names.
Unfortunately there is no ISO standard for name mangling.
So most c++ compilers do that in a different way

FUNCTION OVER LOADING:
TWO OR MORE FUNCTIONS HAVING THE SAME NAME IS CALLED THEY ARE SAID TO BE FUNCTION OVER LOADING.

difference between abstraction and encapsulation with progarammatic eg. hi,just recently i went for an interview .The interviewer asked what is the difference between abstraction and encapsulation with programmatic eg. I gave the answer as encapsulation mean hiding the relevant data which is not useful for the user, eg a electric fan .hiding the information how the electricity is converted into machanical energy. abtraction showing only the relevant data to the user eg electric fan. it look ,its color ,it design etc only relevant data. Then the interviewer asked me, give me some programmic eg .I Said Let assume a web form having control like textbox,button etc. The user can view textbox,button etc this is the eg of abstraction and when the user click on the button how he is redirected is not known by the user is the eg of the encapsulation. Am I Correct .was the answer given by me is perfect .now i am planing to go for an another interview should i give the same answer.IF not please suggest me a better answer.with some good eg Please help
