Arrays of Structures

Let's extend our book program to handle more books. Clearly, each book can be described by one structure variable of the book type. To describe two books, you need to use two such variables, and so on. To handle several books, you can use an array of such structures, and that is what we have created in the next program, shown in Listing 14.2. (If you're using Borland C/C++, read the box "Borland C and Floating Point.")

Structures and Memory The manybook.c program uses an array of 100 structures. Because the array is an automatic storage class object, the information is typically placed on the stack. Such a large array requires a good-sized chunk of memory, which can cause problems. If you get a runtime error, perhaps complaining ...
