Hi, im making a program (for the heck of it) that rewrites it code everytime it is run.(my ambition is to turn it into my c++ teacher and watch her be confuzled as to why she cant read my code and why it does weird things)

Ive just started c++ programming, and managed to rewrite a program so that when it is run a second time, it says hello world. My problem is that I can only input the file as a single string. What I need to do is to be able to input the entire file into the c++ program, as a single object and then ifstream it out with the destination as the source code.

Also, it would help alot if there was someway to write additional lines to an existing text file instead of overwriting what is already there. That way, every time my c++ runs and rebuilds itself, it adds another couple of lines of code to a txt file and when the final iteration is complete, it loads a text file that was created by the program and uses it to program itself. I heard there is some sort of spawn command, can it be used to open up notepad and write to it? it would be awsome if my various programs could open different notepads with various messages.

(as a side note if I can get it to do that, ill use the rand function to load random pieces and parts that fit together and work together as a whole, but do different things.)
ty so much!

Are you actually trying to write a mutating virus?

I have known very few teachers for whom such a stunt would be a good idea.

Is there a typo in there? I really don't get the distinction between what you already figured out how to do vs. what you need help with.

That is pretty trivial.

Do you really need to be working on a lame stunt in order to motivate yourself to learn C++?

Your questions are mostly about basic I/O operations and system requests that should be very easy to learn if you put a little effort into learning them first.

Later, if you're still interested in programming lame stunts, you'll know how.
