Lecture
This lecture discusses the concept of separate compilation in C programming, emphasizing the modular approach to software design. The instructor explains the importance of breaking down a program into smaller, reusable modules, which can be developed and maintained independently. This method enhances code reusability, allowing programmers to avoid redundancy by utilizing existing libraries or previously written code. The lecture covers the structure of modular programs, detailing how to separate declarations and definitions into header (.h) and source (.c) files. The instructor illustrates the compilation process, which consists of compiling individual modules into object files and then linking them to create the final executable. The use of Makefiles for managing compilation is also introduced. Additionally, the lecture highlights the benefits of this approach, such as easier maintenance and the ability to distribute software without exposing source code. Overall, the lecture provides a comprehensive overview of how separate compilation facilitates better organization and efficiency in programming.
