Does how you name a variable have any impact on the memory usage of an application?

Question

Declaring a variable name, how much (if at all) impact does the length of its name have to the total memory of the application? Is there a maximum length anyway? Or are we free

Answer 1

In compiled languages, almost certainly not; everything becomes a symbol in a symbol table. In interpreted languages, the answer is also no, with a few extremely rare exceptions (in certain older versions of Python there would be a difference, for example).
