Overview of the New C++ (C++11/14)

auto is not equal to reference: checking the boundaries of copy and aliasing

Official sample Slides 20—23 (PDF pp.22—25); auxiliary context Slides 8—17 C++98/11 comparison

This course starts by displaying C++98 and C++11 programs side by side. The focus is not on making it as short as possible, but on how new language facilities change the way of expression and the costs. auto can omit lengthy type names, but is still constrained by the rules of value, reference, and constness; when traversing or caching data, omitting a reference symbol may turn “observing the original object” into “copying a snapshot”. Therefore, the original examples first distinguish copy from aliasing by behavior, then use type assertions to verify whether array bounds are preserved. The course lecture notes are materials with instructor annotations; one cannot count all topics like concurrency, move, and library design that appear in the table of contents as having been read; the sample stops at raw strings, so one cannot claim to have completed the entire C++11/14 course based on this.
