Exercise 25-1: In Chapter 1 we defined a histogram program that used our home-grown infinite array. Rewrite the program to use the STL.

Exercise 25-2: Write a program that produces an index for a book. The input file is a set of page numbers and index information of the form:

 <page-number>    <index entry> 

There may be more than one record for each index entry. The output should be a sorted list of index entries such as:

 alpha 10, 20, 30 beta 5, 6, 18 ..... 

Exercise 25-3: Change the cross-reference program you wrote for Exercise 20-1 to use the STL.
