A Note to the Reader

From this point on, our examples will assume that using declarations have been made for the names we use from the standard library. Thus, we will refer to cin, not std::cin, in the text and in code examples.

Moreover, to keep the code examples short, we won’t show the using declarations, nor will we show the necessary #include directives. Table A.1 (p. 866) in Appendix A lists the names and corresponding headers for standard library names we use in this Primer.
