0x0C. C - More malloc, free

C Memory allocation

Concepts

For this project, we expect you to look at this concept:

Automatic and dynamic allocation, malloc and free

Resources

Read or watch:

Do I cast the result of malloc?

man or help:

exit (3)
calloc
realloc

Learning Objectives

At the end of this project, you are expected to be able to explain to anyone, without the help of Google:

General

How to use the exit function
What are the functions calloc and realloc from the standard library and how to use them

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
The only C standard library functions allowed are malloc, free and exit. Any use of functions like printf, puts, calloc, realloc 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
