0x19. C - Stacks, Queues - LIFO, FIFO
Resources
Read or watch -Google -How do I use extern to share variables between source files in C?
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 do LIFO and FIFO mean
- What is a stack, and when to use it
- What is a queue, and when to use it
- What are the common implementations of stacks and queues
- What are the most common use cases of stacks and queues
- What is the proper way to use global variables
Requirements
General
- Allowed editors:
vi
,vim
,emacs
- All your files will be compiled on Ubuntu 14.04 LTS
- Your programs and functions will be compiled with
gcc 4.8.4
using the flags-Wall
-Werror
-Wextra
and
-pedantic
- 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 allowed to use a maximum of one global variable
- No more than 5 functions per file
- You are allowed to use the C standard library
- The prototypes of all your functions should be included in your header file called
monty.h
- Don’t forget to push your header file
- All your header files should be include guarded
- You are expected to do the tasks in the order shown in the project
Github
There should be one project repository per group. If you clone/fork/whatever a project repository with the same name before the second deadline, you risk a 0% score.

Data structures
Please use the following data structures for this project. Don’t forget to include them in your header file.
/**
* struct stack_s - doubly linked list representation of a stack (or queue)
* @n: integer
* @prev: points to the previous element of the stack (or queue)
* @next: points to the next element of the stack (or queue)
*
* Description: doubly linked list node structure
* for stack, queues, LIFO, FIFO Holberton project
*/
typedef struct stack_s
{
int n;
struct stack_s *prev;
struct stack_s *next;
} stack_t;
/**
* struct instruction_s - opcode and its function
* @opcode: the opcode
* @f: function to handle the opcode
*
* Description: opcode and its function
* for stack, queues, LIFO, FIFO Holberton project
*/
typedef struct instruction_s
{
char *opcode;
void (*f)(stack_t **stack, unsigned int line_number);
