    The attached is a C program which reads in information about a list of books from the keyboard, stores the information in an array of structure, and finally displays it on the screen. The information about a book includes its code (an integer value) and price (a floating point value). Code 9999 serves as a sentinel value indicating the end of input. A sample input and output are shown below:
    Sample Input
    Code of Book ? 7731
    Price of Book ? 12.89
    Code of Book ? 2175
    Price of Book ? 8.50
    Code of Book ? 9999
    Sample Output
    CODE PRICE
    7731 12.89
    2173 8.50
    In this project, you should add more functions to this program while preserving its organization. Consider the following functions:
    Count the number of books that cost less than $10.
    Sort all books by Code (You may modify the selection sort function shown in Fig 2.2 on P. 31 accordingly.)
    Search the list for a book given its code.
    In your main program, add statements using the three functions and showing the results on the screen.
