performance, we typically think about the function logic. We’ll see that a well designed function API can have an even larger impact.How will we compare performance? ● Benchmarks at this low level are advance(RandIter& iter, Diff n, random_access_iterator_tag) { iter += n; } ● Access token to make some API available only inside the library (like the default “package private” access modifier in Java) Empty
