C - Stacks, Queues - LIFO, FIFO

Primary LanguageC

0x19. C - Stacks, Queues - LIFO, FIFO

About: In this project, we created a simple interpreter for Monty ByteCodes. The interpreter reads a bytecode file and executes the bytecode commands. The Monty language

Monty 0.98 is a scripting language that is first compiled into Monty byte codes (Just like Python). It relies on a unique stack, with specific instructions to manipulate it. Monty byte code files

Files containing Monty byte codes usually have the .m extension. Most of the industry uses this standard but it is not required by the specification of the language. There is not more than one instruction per line. There can be any number of spaces before or after the opcode and its argument: examples Objectives:

To know what LIFO and FIFO mean
To know what a stack is, and when to use it
To know what a queue is, and when to use it
To know the common implementations of stacks and queues
To know the most common use cases of stacks and queues
To know the proper way to use global variables

General Requirements

Allowed editors: vi, vim, emacs
All files is compiled on Ubuntu 20.04 LTS using gcc, using the options -Wall -Werror -Wextra -pedantic -std=gnu89
All files ends with a new line
There is README.md file at the root of the alx-low_level_programming
Maximum of one global variable is allowed
No more than 5 functions per file
The C standard library is allowed
The prototypes of all the functions were included in the header file called monty.h
All the header files are include guarded

Instruction given:

To use the following data structures for this project, and to also include them in the 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 */ 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 */ typedef struct instruction_s { char *opcode; void (*f)(stack_t **stack, unsigned int line_number); } instruction_t;

List of files/Descriptions: S/N Files Description 1. 2. 3. 4. 5.

Compilation & Output

These codes were compiled using: gcc -Wall -Werror -Wextra -pedantic -std=c89 *.c -o monty
Any output must be printed on stdout
Any error message must be printed on stderr
