Can I pass a saved code on sololearn to the current code? (C++)

Question

Can I use ifstream for some other codes saved on sololearn as an input to the current code? (C++)

Answer 1

No.

You cannot access the files where sololearn save your code. It maybe are not files at all.

You can use "Save As" to create a copy of the current code.

You can use copy and paste to copy the characters.

Is this something you do in your local IDE.
IMHO c++ is a compiled language.
Copying code into other code using fstream during run-time is not possible.
