Error Handling Functions in C Explained — perror(), strerror(), ferror(), clearerr()

In this video, we explore the most important error-handling functions in C programming — perror(), strerror(), ferror(), and clearerr() — along with how to manage program exit states using EXIT_SUCCESS and EXIT_FAILURE. These built-in functions help programmers detect, display, and recover from runtime errors gracefully — ensuring your C programs are more robust, readable, and professional. 👉 What You’ll Learn: How to use perror() to print custom error messages with system error descriptions How strerror() returns a string representation of an error code How to check file operation errors with ferror() How to clear error and EOF flags using clearerr() Handling divide-by-zero errors safely with fprintf() and exit() Using EXIT_SUCCESS and EXIT_FAILURE macros for clean program termination Implementing error-handling patterns such as: Function Split Guard Clause Samurai Principle Goto Error Handling Cleanup Record Object-Based Error Handling 💻 Example Programs Included: Printing detailed error messages using perror() and strerror() Detecting file errors using ferror() Resetting error indicators with clearerr() Handling division by zero with safe exit control 💡 Key Takeaways: perror() and strerror() simplify printing system-level error messages ferror() and clearerr() ensure safe file I/O operations Using proper error-handling patterns keeps your code clean, maintainable, and scalable This tutorial is ideal for students, developers, and C programmers who want to understand real-world error handling in C. 👍 Don’t forget to Like, Comment, and Subscribe for more in-depth C programming tutorials — covering everything from pointers to memory and error management! 👉 Watch Complete Playlist (The Ultimate C Programming Series 💡 | Master Every Concept Step-by-Step) Here -    • The Ultimate C Programming Series 💡 | Mast...   👉 Watch this Practical C Tutorial For Hands On Practice -    • C Programming for Absolute Beginners | Lea...
