The article delves into the abstraction behind a modern Hello World program, focusing on one written in C. It explains the process of converting the code into machine code that the computer’s processor can run and explores the details of the machine code generated by the compiler. The program calls the `puts()` function instead of `printf()` for optimization purposes, and the disassembly reveals the string “Hello World!” with a NULL terminator. The article touches on the complexity of the C library and how it interacts with the main function in the program.
