Problem:

Question 1: Write C++ code to open a document with the name Hello.txt, place the message "Hello, World!" in the document, and exit the document. Re open the file you closed, and read the message into a string variable. Exit out of the file.

Question 2: When do you open the file as an ifstream, as an ofstream, or as an fstream? Could you simply open all files as an fstream?

Question 3: Why is the ifstream parameter of the read_data procedure in the previous question a reference parameter and not a value parameter?

Question 4: What is the difference between a text file, and a binary file?
