Is it possible to declare a variable in C whose name is specified by the user at runtime?

Question

Is it possible to declare a variable in C whose name is set by the user at runtime? If so, how?

Answer 1

No, this is not possible: variable names do not survive at the compilation stage, becoming addresses and offsets, "baked" in compiled binary code.

However, you can declare a variable whose name is given by the developer at compile time using -D or a comparable option of your C compiler.

Answer 2

As dasblinkenlight answered correctly, no.

What you can do and can achieve your implementation goals is to create and maintain at runtime your own dictionary of strings and related values.
