Can You Write C++ Without Libraries?

Описание: What if you deleted every #include from your C++ program?

In this video, I rebuild the classic Snake game in C++ without using any library. No iostream, no std::string, no std::vector—just raw Linux system calls and inline assembly.

Along the way we implement our own interface to the operating system, configure the terminal manually, handle keyboard input, render directly to the console, generate pseudo-random numbers, and build the entire game completely from scratch.

Starter Code (constants & Linux syscall definitions):

Final Code:

Topics covered:

Linux system calls (read, write, ioctl, nanosleep)
Inline assembly (asm volatile)
Terminal programming with termios
ANSI escape sequences
Manual string handling
Keyboard input
Terminal rendering
Game loop architecture
Building C++ without the Standard Library

On this channel I build software from scratch and document the process:

• C++ projects
• Game engine development
• Text editor development
• Programming language/interpreter implementations
• Neovim/Linux workflow
• Systems programming and computer science topics

Most videos focus on understanding how things work internally rather than just using libraries or frameworks.
