Can the 'auto' keyword be used as a storage class specifier in C++11?

Question

Can the auto keyword be used as a storage class specifier in C++11?

Is the following code legal in C++11?

int main() {
   auto int x;
}
         


        

Answer 1

auto int x;

is circular - you are literally declaring the type as an int. given that you had this information - there is no reason to not simply use:

int x;

if you wanted to declare x the type of another variable in scope you can use decltype

using sometype = float;
sometype y;
decltype(y) x;
