using an anonymous array in a ranged for loop in c++

Question

Is there any way to use an anonymous array in a ranged for loop? I'm trying to do something like this

for(auto i: {1,2,3,5,7,11,17}) //do something

Answer 1

Yes there is; it looks like this:

#include <initializer_list>  //MUST INCLUDE THIS!

for(auto i: {1,2,3,5,7,11,17}) //do something

Answer 2

You may have trouble because there is no type ... instead of auto declare "i" as integer.
