C Programming with Command Line Arguments for File Operations

Managing files directly from the terminal is a fundamental skill for any system programmer, yet handling input safely in C can be challenging. This course guides you through the mechanics of reading command line arguments to build a reliable file-copying utility. You will start by understanding how the execution environment passes parameters to your program, ensuring you have a solid grasp of foundational memory and pointer concepts. What you will learn: Understand the roles of argc and argv in receiving terminal inputs; Parse source and destination file paths safely from the command line; Open, read, write, and close files using standard C library functions; Implement robust error checking to handle missing arguments or unreadable files; Apply modern C practices including basic static analysis concepts and safe memory management. This text-only course begins with core definitions and structural patterns before walking you through the step-by-step logic of copying files via the terminal. Designed specifically for beginners, this course requires only a basic familiarity with C syntax and no prior experience with system-level programming. Take your first step toward writing professional, terminal-ready C utilities today.
