Mix C++, C, and Assembly into One Program - Hybrid Program Full Build Tutorial

Want to write a single program that uses C++ for high-level logic, C for portability, and assembly for speed? This video shows exactly how to do it.

We build a complete hybrid program from scratch:
- driver.cpp - contains main(), prints intro, calls assembly
- c.c - simple printf() function
- cpp.cpp - C++ function (with extern "C" to disable name mangling)
- hello.asm - assembly module that prints messages, calls C and C++ functions

You?ll see:
- Why hybrid programs matter
- How source files ? object files ? final executable
- The role of the driver and why main() lives once
- Name mangling in C++ and how extern "C" fixes interop
- Global / extern in assembly to expose and call functions
- A clean Makefile that compiles each module separately
- Live build and execution with output explained line-by-line

By the end you?ll know how to call across languages safely, pass basic args via registers, and structure projects for fast incremental builds.

No prior assembly required - just basic C/C++ familiarity. Code is copy-paste ready.
