    Write a little program and test by yourself.
    See the documentation:
    - http://www.cplusplus.com/reference/i...m/istream/get/ ,
    - http://www.cplusplus.com/reference/i...m/ostream/put/ ,
    - http://www.cplusplus.com/reference/iostream/cin/ ,
    - http://www.cplusplus.com/reference/iostream/cout/ .

    Edit: Sorry, I forgot to answer your questions.

    Q: What is the function of cin.get(c)?
    A: The function is to get one character.

    Q: What will cout.put(c) print?
    A: It will print the c character.


    The following example will help you understand these functions
    Code:
    #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.
