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
