Referencing Arrays Inside Strings
As you know from Chapter 2, you may place a variable inside a string using double
quotes. The variable's value will replace it. A single-dimensional array indexed by
integers will be interpreted correctly inside double quotes, but other uses of arrays are
problematic. To force the use of multidimensional arrays, use curly braces. These
suspend the normal parsing that occurs within a double-quoted string. Of course, you
may always concatenate strings. Listing 5.8 explores some different ways to use arrays
inside strings.
