How to pass a mathematical function to c++ code?

Question

C++ / C#

The program at some point calculates a function, for example: 5*(x-6)^3-23. I hardcoded it, everything works. And if there are many such mathematical functions, and they can be different? How to give the user the opportunity to enter such a mathematical expression himself?
