Sorting Records with File IO in C

Working with external data is a fundamental skill for any programmer, yet managing file inputs and outputs in C can often feel intimidating to beginners. This text-based course guides you step-by-step through the process of reading structured records from a file, organizing them in memory, and sorting them systematically. You will start by mastering foundational file handling concepts, learning how to safely open, read, and close files in C before moving on to data manipulation. What you will learn: Understand standard C file input and output operations; Parse structured student records from raw text files into memory; Apply string comparison functions to sort data alphabetically; Implement structured memory management using C structs; Debug common file access errors and handle edge cases safely. The course begins with core definitions and basic file operations, then moves into structuring your data, and concludes with practical sorting algorithms applied to real file data. This course is designed for beginner C programmers who want to transition from basic console programs to file-based applications, with no advanced prerequisites required.
