C++ (using files as database)

Question

How can i permanently create a file and store things to it every time it runs and will still be accessible later in --C++

Answer 1

Once you create a file it will be permanently saved.

Answer 2

I just want to complement the answer of Dark Angel.

If you want to use a file as db, C++ class fstream and the related ones offer many options: for example you can have a text file or a binary file (with this one you can save your objects directly), you can open a file only for reading/writing or both, the new content can be appended at the of the file, etc...

As an example, see this code:

You will need to execute it on your machine to watch the file being modified.

Good coding.
