Lecture
This lecture focuses on handling command line arguments in C programming. It begins with an overview of the main function's parameters, specifically argc and argv, which represent the number of arguments and the array of argument strings, respectively. The instructor explains the significance of these parameters, illustrating how argc counts the total number of arguments passed, including the program name itself. The lecture progresses to demonstrate a structured approach to processing these arguments through a dedicated function. The instructor outlines three types of command line arguments: mandatory arguments, optional arguments, and optional arguments that require additional input. Each type is explained with practical examples, such as file names and display options. The lecture emphasizes the importance of modular programming and error handling when processing command line inputs. By the end, students gain a clear understanding of how to implement argument handling in their C programs, ensuring they can effectively manage user inputs and enhance program functionality.
