Description: Explains how the rules for initializing references differ from the rules for initializing pointers.
Reference Initializations | Embedded The rules for initializing references resemble the rules for initializing pointers. But they do differ. And you should know how. I began this year's columns with a series on reference types in C++. (See "An Introduction to References," January 2001, p. 81 for the first of these.) I then realized I needed to employ the concepts of lvalues and rvalues in further discussions of references, so I took a little detour to explain them. (See "Lvalues and Rvalues," June 2001, p. 70.) Now I'm returning to my explanation of references with a look at one aspect of reference initialization that many programmers find somewhat surprising.
