1Does this answer your question? [converting a variable name to a string in C++](https://stackoverflow.com/questions/3386861/converting-a-variable-name-to-a-string-in-c) – Jan Schultke Aug 17 '20 at 17:18

Please give an example of how you want to use this code. – quamrana Aug 17 '20 at 17:19

Why do you want to do that? Perhaps use a data structure instead? Like a `std::vector
` or `std::map – Tanveer Badar Aug 17 '20 at 17:19`. -

4C++ is compiled. The compiler removes variable names. – QuentinUK Aug 17 '20 at 17:23

stringify with pre-processor is the way to go actually. – Jarod42 Aug 17 '20 at 17:40

`int i = 3; char const* GetVarName(int& x) { if (&x == &i) return "i"; return "unknown;" }` Add all the variables you are interested in. – Eljay Aug 17 '20 at 20:11

You could try to stringify the variable using the preprocessor. In the posted link by Schultke there are some examples using macro in order to achieve that.
