Nested while loops C - Functions Learning to Program in C (Part 06) (stop at 14:00) What is the purpose of a function prototype? C - Header Files (stop before the “Once-Only Headers” paragraph) Learning Objectives At the end of this project, you are expected to be able to explain to anyone, without the help of Google:

General What are nested loops and how to use them What is a function and how do you use functions What is the difference between a declaration and a definition of a function What is a prototype Scope of variables What are the gcc flags -Wall -Werror -pedantic -Wextra -std=gnu89 What are header files and how to to use them with #include Requirements General 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 folder of the project is mandatory Your code should use the Betty style. It will be checked using betty-style.pl and betty-doc.pl You are not allowed to use global variables No more than 5 functions per file You are not allowed to use the standard library. Any use of functions like printf, puts, etc… is forbidden You are allowed to use _putchar You don’t have to push _putchar.c, we will use our file. If you do it won’t be taken into account In the following examples, the main.c files are shown as examples. You can use them to test your functions, but you don’t have to push them to your repo (if you do we won’t take them into account). We will use our own main.c files at compilation. Our main.c files might be different from the one shown in the examples The prototypes of all your functions and the prototype of the function _putchar should be included in your header file called main.h Don’t forget to push your header file Copyright - Plagiarism You are tasked to come up with solutions for the tasks below yourself to meet with the above learning objectives. You will not be able to meet the objectives of this or any following project by copying and pasting someone else’s work. You are not allowed to publish any content of this project. Any form of plagiarism is strictly forbidden and will result in removal from the program. More Info You do not have to understand the call by reference (address), stack, static variables, recursions or arrays, yet.
