CPP1114 — Use C++11 using instead of typedef in all C++11 example code

C++11 introduced the "using" keyword (see https://en.cppreference.com/w/cpp/language/type_alias) as alternative way to specify a type alias. In terms of C++11 support usage it would be a good thing to update all example C++11 code within the specification to use "using" instead of "typedef"

Use the C++11 type alias feature in examples

C++11 has type aliasing with the "using" keyword, which is typically preferred to using the "typedef" syntax inherited from C.
