[mahor1989]

i know it takes one character at a time but if i give input HELLO WORLD what it will take then just H. And what will cout.put(c) print then?

Write a little program and test by yourself.
See the documentation:

Edit: Sorry, I forgot to answer your questions.

The following example will help you understand these functions

#include <iostream>
#include <fstream>
using namespace std;

int main () {

  char ch;
  ofstream outfile ("test.txt");

  do {
    ch=cin.get();
    outfile.put (ch);
  } while (ch!='.');

  return 0;
}

This example writes to a file everything the user types until a dot (.) is typed.
