I know that I can save and read .txt file using c++. But I'm wondering, can I run a sourcecode written in a .txt file(or whatever file it is) like an another function but in another file. Picking up what am I pointing?
Really appreciate for responds and if it exist, can someone provide me a sample sourcecode/program for it?
Thanks alot!
I'm not aware of any way to compile source code on the fly and call it from within your current program (rather than as a separate executable). Why would you want to do that anyway? Just tinkering?
Oh well. Thanks men! Appreciate alot. But I'm still hoping that running a sourcecode in a .txt file is a thing is c++, hoping. Haha
The reason? I'm thinking a unique way to make a simple database using c++.
This certainly can be done: just as a compiler can be written in C++, an interpreter for a programming language can be written in C++. I believe that there are existing interpreters for (possibly some subset or earlier version of) C++ itself, but I cannot recommend any as I have never tried one.Originally Posted by forpetesake568
You might want to investigate existing database software. For example, the source code for SQLite is freely available, though it is in C rather than C++, but the same can certainly be done in C++. The documentation on the SQLite Virtual Machine begins with this introduction:
In order to execute an SQL statement, the SQLite library first parses the SQL, analyzes the statement, then generates a short program to execute the statement. The program is generated for a "virtual machine" implemented by the SQLite library. That virtual machine is sometimes called the "VDBE" or "Virtual DataBase Engine".
