Learn and Master C Programming - Nesting Header Files & Multiple Inclusion Problem

The video tutorial discusses the concept of nested includes in programming, advising against their use unless necessary. It introduces the double inclusion problem, where a header file is included multiple times, causing compilation errors. Two solutions are presented: using conditional inclusion with ifndef and using pragma once. A demonstration in Visual Studio shows how to set up a project and solve the multiple inclusion problem. The tutorial concludes with best practices for organizing code, recommending that functions be placed in source files rather than header files.
