8.10 Pointer-Based Strings (Optional)

We’ve already used the C++ Standard Library string class to represent strings as full-fledged objects. Chapter 21 presents class string in detail. This section introduces C-style, pointer-based strings (as defined by the C programming language), which we’ll simply call C strings. C++’s string class is preferred for use in new programs, because it eliminates many of the security problems and bugs that can be caused by manipulating C strings. We cover C strings here for a deeper understanding of pointers and built-in arrays, and because there are some cases (such as command-line arguments) in which C string processing is required. Also, if you work with legacy C and C++ programs, you’re likely to encounter ...
