1. Read carefully code examples in Chapter 11, especially those for random-access file processing (11.10, 11.11, 11.14, and in particular 11.15). Make sure you fully understand all the examples
before starting.
2. Define 6 functions for the 6 requirements REQ#1 to REQ#6.
3. Your program should be able to test if there is already an existing file containing some book
information. If there is, use it but do not overwrite it; otherwise, create a new file.
4. Consider using the test data file “assignment4_test_data.txt” to test your program. In Windows you can use the following command lines.
D:\PROG12974\Assignment>assignment4_sun < assignment4_test_data.txt
D:\PROG12974\Assignment>assignment4_sun < assignment4_test_data.txt > output.txt
From a Linux terminal you can do it like this:
username$> cat assignment4_test_data.txt | ./assignment4.out > output.txt
5. Do NOT use goto statement or recursive functions. Global arrays and structure definition are
