The File Path Mistake Every Beginner Makes in C (and Beyond)

Want some guidance to help you learn how to code? 📘Download my FREE 30 day beginner coding challenge here: https://henrikmdev.com/challenge After coding some simple projects, maybe you want to start using a CSV file or a text file as input into your C program. But then you run into a frustrating problem: how do you actually open that file, or access it from your program? The most common way to get data from a file in C is by using the fopen function. fopen is really simple and widely used—but sometimes it just doesn’t work right. You try to run your code, and instead of getting the file data, you get a segmentation fault. Debugging this issue can feel confusing and overwhelming, especially if you’re a beginner. In this video, I’ll break down how to properly use fopen and make sure you can reliably read files in your C programs. We’ll talk about the difference between your source file directory and your working directory, why your program can’t always find your .csv or .txt file, and how to fix it. I’ll also explain how relative paths and absolute paths work, and when to use each. By the end of this video, you’ll understand how to correctly set up your file paths, prevent segmentation faults, and write more reliable C programs that can handle files without crashing. In this video, you'll learn: 📂 The difference between source file directories and working directories in C. 🛠️ How to use relative and absolute paths with fopen to correctly open files. ✅ Best practices for checking file errors and closing files to prevent resource leaks. 0:00 – Introduction: The problem with opening files in C 0:14 – Using fopen to read files 0:27 – Why fopen sometimes fails 1:06 – Understanding source vs working directory 2:01 – Finding your working directory with the executable 2:44 – Moving files into the correct directory 3:05 – Using relative paths (../) to access files 4:39 – Absolute paths explained 5:48 – Why you should avoid hardcoding absolute paths 6:42 – Sharing your program with others using relative paths 7:02 – Error handling: checking if the file opens 8:41 – Using perror for more descriptive error messages 9:32 – Closing files with fclose 10:14 – Why forgetting fclose leads to resource leaks 11:02 – Final thoughts on good coding practices ================================================= 📚 Stay Tuned for More: If you found this video helpful, make sure to like and subscribe to our channel for more programming tutorials and tips.
