[ios_base]

Why are you asking what a manipulator is? Can you be more specific?

Do you maybe want to overload the C++ manipulator functions?

and std::endl is manipulator just wonder what is it
plz help
that's all i know
since i am newbie i don't know how to be more specific

Manipulator in your context...

it is just a 'thing' which manipulates stream(std::cout in your example).
There are more of these manipulators, e.g. you are able to set big letter for example
(it is a pseudocode, I do not remember what is a value)


std::cout << std::big_letters << "hello" << std::endl;

result is:


HELLO\n


hod139 gave you a link

http://www.cprogramming.com/tutorial/iomanip.html

There is a good explanation.

errr is there a easier definition for it
is it basically control ???

plz help me i mean i still don't quite get it

[skullmunky]

i guess you could call it control, or a better description would be "filtering". the manipulators in the examples in that link below are better examples - they "manipulate" or "filter" the text you're printing by formating it in different ways, changing to upper case or lower case, controlling how many decimal places get printed, etc.

std::endl is "end line" - a newline or carriage return. it doesn't really do any manipulation or filtering, but it's included in the "manipulators" category anyway.
