Write the definition for a void function called text_to_screen that has

one formal parameter called file_stream that is of type ifstream. The

precondition and postcondition for the function are as follows:

//Precondition: The stream file_stream has been connected

//to a file with a call to the member function open.

//Postcondition: The contents of the file connected to

//file_stream have been copied to the screen character by

//character, so that the screen output is the same as the

//contents of the text in the file.

//(This function does not close the file.)

void text_to_screen(ifstream& file_stream)

{

char next;

file_stream.get(next);

while (! file_stream.eof( ))

{

cout << next;

file_stream.get(next);

}

If you prefer, you can use cout.put(next); instead of cout << next;.
