Equivalent in C++ to JavaScripts "eval()" function?

This article has not been rated yet. After reading, feel free to leave comments and rate it.

Question:

Is there an equivalent in C++ to the "eval()" function that is found in Javascript?

Answer:

JavaScript is an interpreted language which makes it easy to provide a formula interpreter as a standard function. C++ is compiled and adding an "eval()" like function would mean major overhead. Therefore such a function is missing in C++ standard libraries.

Such an ignorant answer. Yeah try looking up some data structures, or maybe a lexical analysis class with c++ restricting your search to Universities with google. I seem to remember seeing some ideas that would be equivalent or close to equivalent.

Anonymous, what's your point? It is possible to implement eval() in a compiled language - the original answer does not deny that.
But it would be a 'major overhead', while in Javascript, it's part of the interpreter.
