Problem
You are designing an automated library catalog system. For each book, there is a catalog entry consisting of the call number (up to 10 characters), the number of copies in the library (a positive number), the author (up to 30 characters), the title (up to 100 characters), and a description of the contents (up to 300 characters).
a. Write the type definitions necessary to contain this information in a direct file.
b. Estimate how many characters of file space are required to hold all the catalog information for the library. (Assume that an integer value occupies the equivalent of four characters in the file and that the library has 50,000 book titles.)
c. How many book records can a computer with 1,440,000 characters of file space hold?
