Program 2 Introduction To Ccsci 112 Fall 2018objectives Practice

Using the same team you had for program 1, create a program that reads in a list of CSCI classes from a file (must use file pointers). Store the list in a data structure. Allow the user (a student) to have the following options: 1) Print all classes by CSCI number (include all information) in order of CSCI number. 2) Print all classes available on MWF or available on TR in order of times. 3) Print the class available at a specific time (test this with MWF 0900 and TR). 4) Print classes available to freshman, sophomore, junior or senior (corresponds to last number on each line in the input file) in order of CSCI number. 5) Quit. All output will be written to a file (must use file pointers). Requirements: You must use the input file in /home/csci112 called classes.txt to input the data. You must provide the options to the user on the screen as shown above in description. You must write all information asked for by the user to an output file.

This means that you will need to interact with the user (asking for options) by printing to STDOUT but print all the responses to the queries to a file. To print class information, print in the following order: Title, Class number (ex: CSCI112), available for (freshman, soph…, day, time). You must loop on user queries until the user selects the quit option. You must exit with a failure if any error is found in user input. Place each function or group of functions in a separate file (.c) and have a Makefile that compiles all your code together to make the executable.

The program aims to facilitate the management and querying of a university's course schedule stored in a file. It is a comprehensive C application designed to handle class data efficiently through file I/O, data structures, and user interaction. The core objectives involve reading class information from a specified file, organizing it in appropriate data structures, processing user requests, and outputting the requested data to a designated output file. This project emphasizes good programming practices, modularity, and precise adherence to specifications, making it an excellent exercise in file management, data handling, and user interface design within C programming.

At the heart of this application lies the reading of class data from a text file located at /home/csci112/classes.txt. This file contains details about various CSCI courses such as course number, schedule, availability, and student year. Effective parsing of this data requires implementing robust file handling using FILE pointers, an approach that ensures efficient and error-robust input processing. Once read, the data is stored in a suitable data structure—most likely an array of structs—each holding information about a particular class, including its title, course number, days, times, availability for student levels, etc.

The program then provides the user with a menu of options, displayed on the console, allowing various queries on the stored class data:

• Print all classes sorted by CSCI number, including full details.
• Filter and print classes available on specific days (MWF or TR), sorted by times.
• Find classes available at a specific time (e.g., MWF at 0900), and display matching classes.
• Filter classes based on student level (freshman, sophomore, junior, senior), which requires conversion between label strings and numerical representations stored internally.
• Exit the program.

Critical to the application's design is that all output generated in response to user queries should be written to an output file, also handled via file pointers. The standard output (console) should solely be used to display the menu and prompt, while all the class data responses are redirected to the output file, enabling easy review and record keeping.

The program must accommodate repeated querying until the user chooses to quit. It should handle erroneous inputs gracefully by terminating with an error message. The code organization mandates separating functions into different source files (.c), promoting modularity, with a Makefile to compile all components into a single executable. Proper documentation and code comments are essential to demonstrate good programming practices.

In summary, this project combines file I/O, dynamic data management, user interaction, and modular programming principles to create a functioning C program that reads, processes, queries, and outputs class schedule data, fulfilling the specified requirements comprehensively.
