Dr_Quine

A quine is a program that prints its own source code without reading any file. This project implements quines in 3 languages: C, x86-64 Assembly, and Shell.

The replication logic relies on a string that contains the source code of the program itself. When a special placeholder character ($) is encountered while printing that string, the program switches into escape mode and prints the string again — this time with special characters escaped — so the output is valid source code. Every other character is printed as-is. The result is a perfect copy of the original source.

Programs

• Colleen — simple quine, prints its source to stdout
• Grace — writes its source into a new file Grace_Kid.c
• Sully — generates and compiles a child program, then runs it, counting down from 5 to 0

Warning: The assembly code in this project does not follow the System V AMD64 ABI — calling conventions, callee-saved/caller-saved registers, and stack alignment are not properly respected. This was my first program in assembly.
