String to code

Question

I got a input variable
string code = "y = x + 1"

Is it possible to use this code like
Code()

I know this is not the correct way but i want something like that

Answer 1

You'd have to make an interpreter that interprets the string.
But this will get big very quickly if you want to add more features, you'll probably get a new language by the time you're done.

Instead, you can use a scripting language and embed it into C++.

Python
Lua
Ruby
Are probably among the more popular ones.

An example with Lua:
