Question

Theoretical question only – why i can’t write such code:

auto auto foo = 0;

First auto keyword – storage class specifier (yeah, i know that it’s useless and deprecated in C++11), second auto keyword – auto type-specifier.

So what’s wrong?

And again – i don’t really want to use this in real code.

Answer 1

The auto storage class specifier is not “useless and deprecated in C++11,” it has been removed entirely. The auto keyword is no longer a storage class specifier and cannot be used as one.

In C++11, auto is a simple type specifier.
