0x00-hello_world

Project: 0x00. C - Hello, World

Description

This project is an introduction to the C programming language. It covers the basics of C, including compiling, assembling, and linking programs, as well as writing simple programs that print text and determine the size of data types.

Tasks

Task File Description
0. Preprocessor 0-preprocessor Runs a C file through the preprocessor and saves the result into another file.
1. Compiler 1-compiler Compiles a C file but does not link.
2. Assembler 2-assembler Generates the assembly code of a C code and saves it in an output file.
3. Name 3-name Compiles a C file and creates an executable named cisfun.
4. Hello, puts 4-puts.c Writes a C program that prints exactly "Programming is like building a multilingual puzzle".
5. Hello, printf 5-printf.c Writes a C program that prints exactly "with proper grammar, but the outcome is a piece of art".
6. Size is not grandeur, and territory does not make a nation 6-size.c Writes a C program that prints the size of various types on the computer it is compiled and run on.
7. Intel 100-intel Generates the assembly code (Intel syntax) of a C code and saves it in an output file.
8. UNIX is basically a simple operating system, but you have to be a genius to understand the simplicity 101-quote.c Writes a C program that prints exactly "and that piece of art is useful" - Dora Korpar, 2015-10-19.
