Concepts For this project, students are expected to look at this concept: Concept Mathilde Resources Read or watch: Everything you need to know to start with C.pdf (You do not have to learn everything in there yet, but make sure you read it entirely first) Dennis Ritchie “C” Programming Language: Brian Kernighan Why C Programming Is Awesome Learning to program in C part 1 Learning to program in C part 2 Understanding C program Compilation Process Betty Coding Style Hash-bang under the hood (Look at only after you finish consuming the other resources) Linus Torvalds on C vs. C++ (Look at only after you finish consuming the other resources) man or help: gcc printf (3) puts putchar Learning Objectives At the end of this project, you are expected to be able to explain to anyone, without the help of Google: General Why C programming is awesome Who invented C Who are Dennis Ritchie, Brian Kernighan and Linus Torvalds What happens when you type gcc main.c What is an entry point What is main How to print text using printf, puts and putchar How to get the size of a specific type using the unary operator sizeof How to compile using gcc What is the default program name when compiling with gcc What is the official C coding style and how to check your code with betty-style How to find the right header to include in your source code when using a standard library function How does the main function influence the return value of the program Requirements C Allowed editors: vi, vim, emacs All your files will be compiled on Ubuntu 20.04 LTS using gcc, using the options -Wall -Werror -Wextra -pedantic -std=gnu89 All your files should end with a new line A README.md file at the root of the repo, containing a description of the repository A README.md file, at the root of the folder of this project, containing a description of the project There should be no errors and no warnings during compilation You are not allowed to use system Your code should use the Betty style. It will be checked using betty-style.pl and betty-doc.pl Shell Scripts Allowed editors: vi, vim, emacs All your scripts will be tested on Ubuntu 20.04 LTS All your scripts should be exactly two lines long ($ wc -l file should print 2) All your files should end with a new line The first line of all your files should be exactly #!/bin/bash More Info
