Assigning consecutive integers to a list of variables

Question

How to rewrite the following in a more compact form?

constexpr unsigned int dog=1;
constexpr unsigned int cat=2;
constexpr unsigned int elephant=3;
...
constexpr unsigned int zebra=1000;

Ideally, I'd like something like

dog,cat, elephant, ..., zebra = range(1,1000)

Answer 1

Assigning consecutive integers to a list of variables

They're not really variables if they can't vary.

You can just replace

constexpr unsigned int dog=1;
constexpr unsigned int cat=2;
constexpr unsigned int elephant=3;
...
constexpr unsigned int zebra=1000;

with

enum Animal: unsigned {
  dog=1,
  cat,
  elephant,
  ...
  zebra
};

if that's all you want.
