Define a function called send_line that takes one argument that is an output stream. When called, send_line reads one line of input from the keyboardand outputs the line to the output stream given as its argument.

You should be able to call your function using either cout or an outputfile

stream as the argument to your function send_line. (If the argument

is an output-file stream, then the stream is connected to a file before the

function is called, so send_line will not open or close any files.) For

example, the first of the following calls to send_line copies a line from

the keyboard to the file morestuf.dat, and the second copies a line from

the keyboard to the screen:

ofstream fout;

fout.open("morestuf.dat");

cout << "Enter 2 lines of input:\n";

send_line(fout);

send_line(cout);
