Files in C++

You can save data on disk files and retrieve them at any time

• In C++ you can use file streams which behave very similarly to the cin and cout streams.
• You must include <fstream.h>

before you use a file:

• declare an object of type fstream which will deal with your file
• associate your fstream object with an actual file on the disk (open the file)

what can you do with an fstream object?

• open - (filename,access)
• >>   - input to your variables
• <<   - output from your variables
• close - close the file

Example:

#include <fstream.h>

       void main()

{

fstream mylist;

mylist.open("thefile.txt",ios::out);

mylist<<"This is it"<<endl;

mylist.close;

       }
