Since a Makefile is required for this lab, you must create the appropriate compile statements to create a lab3.o file, which would then create a lab3 executable. Graders will be downloading your lab3.zip file from Carmen, unzipping it, and then executing make from a linux command line prompt. Your program must compile --without errors or warnings - via commands within the Makefile. Given valid input, your program must also run without having a seg fault or other abnormal termination. You are welcome to do more than what is required by the assignment as long as it is clear what you are doing and it does not interfere with the mandatory requirements. LAB DESCRIPTION BOOK LIST WITH FAVORITES (100%) Mandatory filename: lab3main.c readtitles.c getfavorites.c savedata.c Mandatory executable name: lab3 PROBLEM: The user of your program will use it to create a list of books s/he had read, and then your program will create a subset of this list as a favorites list. You will not know how many books the user wishes to include on the list until the program gets its first input. After the user has finished entering all of the books titles, you must prompt the user for a subset of the book titles to put on a "favorites list. You will want to review Slide Deck 13, slides 46 through 50 to help you visualize how the data should be stored. You must use pointers within this project such that you have one array of char * that contains all of the book titles and an array of char ** for favorites. The third item this program does is ask the user whether or not s/he want to store a copy of their information in a file on disk. If so, you program will ask for a file name and store the information within the file in the format shown in the example below. First, you should prompt the user to enter the number of books titles they plan to enter. The user will enter an integer greater than or equal to 1 to indicate the number of book titles. (NOTE: Make a point to test your program to ensure entering just 1 book title works.) You must then dynamically allocate enough memory to hold all books titles. You can assume that there will be no book titles with more than 60 characters. Remember that all character strings in Care null terminated and that you have to allocate space in your string for that null character, in addition to the length of the string you wish to have. Also realize that you won't know how many of the 60 characters the book title will fill until after you read the title. You should then prompt the user to enter each book title on a separate line. You must assume that each book title could contain more than one word and will be separated by a newline character from the next book title. You can assume that the user will enter the input in this format, so you do not need to check to make sure that the format of the input meets this description, and you do not need to reject input which is not properly formatted. You can also assume that the user's input is correct. If you do not completely understand this description jump to the bottom of this file and check out the example data. You can assume that there will be no book title duplicates. After reading in all of the book titles, your program should print all of the book titles back out with a number next to each title. Then ask user to pick how many books s/he wishes to put on their favorites list. The favorites list will consist of a subset (up through all books on the titles list) of the books on the titles list. Once you have this number, you will have to dynamically allocate enough space for an array of 8-byte addresses. The user will then specify by title number which books should be included on the favorites list. Your program should then print out the books on the favorite list. Next, your program should ask whether or not the user wishes to store in an ASCII file the information they have input. They indicate yeso with 1 or 2. If the user wishes to save the data, you must open a file and store the information in the file based on the format shown below, close the file, and then confirm to the user the data has been saved. Prior to exiting the program, you must free() all dynamically allocated memory. You can determine whether you have managed to accomplish this with the valgrind tool. CONSTRAINTS: Source code files (.c files) submitted to Carmen as a part of this program must include the following at the top of the file: /* BY SUBMITTING THIS FILE TO CARMEN, I CERTIFY THAT I HAVE ** STRICTLY ADHERED TO THE TENURES OF THE ** OHIO STATE UNIVERSITY'S ACADEMIC INTEGRITY POLICY. */ If you choose not to put the above comment in your file, you will receive no points for the lab. - You must comment your code You must create and submit a Makefile that will be used to create your zip file and your executable, lab3. This Makefile must define at least each of the following targets: all, lab 3, lab3.zip, lab3main.o, readtitles.o, getfavorites.o, savedata.o, clean. Creating this file at the beginning of your development process and using it as you work, will allow you to test your Makefile for proper operation. - Separate your code into different functions so that your main() is uncluttered and easy to understand. Pointers to your two arrays should be declared in your main program. You should have a different function that is called from main(that performs each of the following tasks: 1. populates the titles array in a file called readtitles.c populates the favorites array in a file called getfavorites.c saves data to a file in a file called savedata.c - You must create a lab3.h file that holds the prototypes to these three functions. - No variables can be declared outside of a block. That is, no variables can be declared as global. - You may only use getchar(), printf(), fprintf(), and scanf() for any I/O needs you have while writing this program. - You must use pointers within this project such that you have an array of char pointers that contains the addresses of all of the book title strings (the variable that holds the address to this array would have to be declared as char **) and an array for favorites that contains addresses from the titles array (the variable that holds the address to this array would have to be declared as char ***). - Be sure your directions to the user are clear so they are sure to enter the input data correctly. - You cannot use statically declared arrays in this lab to store any of the user data other than the filename in which to store user's information. - Your code should work correctly for ANY NUMBER of book titles (including just 1 and up to the limits of available memory, of course), and these numbers are not known in advance. - You will need to use pointers to access user data - the valgrind program should say that your program has no memory leaks - You may not access any of the allocated storage space using indexes, as is usually done for a statically declared array, but only by using pointers and pointer arithmetic. HINTS: 1. You will likely want to dynamically allocate an array of character pointers (one for each title) and a set of pointers to character pointers for the favorites list. 2. You will also likely want to dynamically allocate a character string for each book title. Since you can't know how long the book title is for any particular book, you will have to allocate the maximum size for a book title for every book. LAB SUBMISSION Always be sure your linux prompt reflects the correct directory or folder where all of your files to be submitted reside. If you are not in the directory with your files, the following will not work correctly. You must submit all your lab assignments electronically to Carmen in zip file format. The format of zip command is as follows: [jones.5684@f1 lab3] $ zip where where
