Functions that get called automatically

[Saurabh]

Hi All,

I want to know something.
Apart from Constructor and Destructor are there any other functions
which get called automatically without user calling them?
If yes,please tell me which are the functions,or tell me some resource
to know details regarding
this thing.

Thanking You

the program entry point (usually called "main")

main is the entry point.I am talking about something like.....
well like constructors and destructors are automatically called
for object initialization and clean up.
Like that only.
One of my friend was asked in an interview that there are such 4 kinds
of functions
including 1.constructor 2. destructors.
I want to know about other 2.
anyways...
thanks for your response.

IIRC:

C'tors, D'tors, CRT initialization, main

Look up "special member functions".

Nope. But the compiler might create functions automatically (copy
constructor, assignment operator) if you do not declare them
explicitly.

There are the atexit() functions.
