Using Strings in an Array

The two most common ways of getting a string into an array are to initialize an array to a string constant and to read keyboard or file input into an array. Listing 4.2 demonstrates these approaches by initializing one array to a quoted string and using cin to place an input string into a second array. The program also uses the standard C library function strlen() to get the length of a string. The standard cstring header file (or string.h for older implementations) provides declarations for this and many other string-related functions.
