How Linkers Work: Linking Code, Virtual Memory, and Module Jumps Explained

Hey everyone, let?s talk linkers! In this video, we unpack the general idea of linking in programming?taking your source code, turning it into object files, and stitching them into an executable. We dive into virtual memory, how programs use offsets, and why jump instructions matter across modules. Using simple assembly and C++ examples, we?ll show how linkers lay out modules, handle labels, and make function calls work. Whether you?re a beginner or a coder curious about what happens under the hood, this is for you!

Let?s keep learning and have some fun with code! #Programming #Linker #VirtualMemory #CodingExplained
