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
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.

for (index = 0; index < numOfBooks; index++)
printf("%10d%10.2fn", list[index].code, list[index].price);
