whats the difference between /n and endl?

[misplaced]

nothing

all it does is prevent extra shift keying
cout << somevariable << endl;
instead of
cout << somevariable << "\n";

[Vicious]

\n is an escape sequence.

And endl does the same thing but its a standatd strem thingie.

I really dont know the technicalities. Im sure someone does.

example

cout << "Line one\nLine two";
cout << "Line one" << endl << "Line Two";

ok, there is a difference....

endl is a global function which returns '\n'
<< is an overloaded operator which tells the ostream class cout how to handle the data type that follows

i believe endl also calls flush to flush the stream

[NiVaG]

ok....when did a stream come into the picture?

[manofsteel972]

endl is a manipulator in the ostream class. When inserted into an output stream it inserts a newline character then flushes the stream. It is cheaper to just use "\n" then to use endl because flushing the stream unnecessarily can slow down your program.

a stream came into the picutre you you put
#include <iostream>
in your program

Actually I believe NiVaG was referring to your seemingly irrelevant explanation of the insertion operator.

[Perspective]

cout << somevariable << "\n";

when using \n be sure to use single quotes to insert the character. When you use double quotes it creates a null terminated c-string which will cost you an extra sizeof(char)

Here is a sample implementation of endl:

template<class _Elem, class _Traits> inline
	basic_ostream<_Elem, _Traits>&
		__cdecl endl(basic_ostream<_Elem, _Traits>& _Ostr)
	{	// insert newline and flush stream
	_Ostr.put(_Ostr.widen('\n'));
	_Ostr.flush();
	return (_Ostr);
	}

When talking about endl, you are implying streams as endl is an operator to ostream (a stream class). So there is definitely relevance there, adn as stated before endl does a flush() after "\n".

Sometimes when I use cin.get() to pause the program before ending (keep the console open long enough to read it) it doesn't work by itself and I have to precede it with cin.ignore(). I understand that this is because there is still a \n in the input buffer....maybe? Would using endl, since it flushes the stream, make it so that I wouldn't have to enter cin.ignore()? Or are they completely unrelated things?

Couldn't you use cout.flush() and cin.flush() before cin.get()?

I don' know. That's the first time I've seen those. I'll check them out. Thanks.

Since endl flushes the output stream, it wouldn't help much in clearing the input stream.

I believe flush is only defined for output streams, so it wouldn't work for cin.
