- This is an introductory project that explains:
- 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
- How to work with git submodules
- Ubuntu 14.04 LTS
- GCC version 4.8.4 with flags: -Wall -Werror -Wextra and -pedantic
-
Clone the repository
https://github.com/ibeckermayer/monty.git -
Compile the program
gcc -Wall -Werror -Wextra -pedantic *.c -o monty -
Run the program as follows:
- Usage:
monty <file.m> - Ex:
./monty ./bytecodes/00.m
There are multiple .m files to choose from in the bytcodes files that run different Opcode functionality. Below is a table of all the Opcode options. Each file in the bytcodes folder contains different Opcodes that run their specific functionality.
| Opcode Name | Opcode Description |
|---|---|
| push | pushes an element on to the stack |
| pall | prints all the values on the stack, starting from the top |
| pint | prints the value at the top of the stack |
| pop | removes the top element of the stack |
| swap | swaps the top two elements of the stack |
| add | adds the top two elements of the stack |
| nop | doesn't do anything |
| sub | subtracts the top element of the stack from the second top element of the stack |
| div | divides the second top element of the stack by the top element of the stack |
| mul | multiplies the second top element of the stack with the top element of the stack |
| mod | computes the modulus of the second top element of the stack by the top element of the stack |
| comments (#) | add a # to the beginning of the line to comment in the file |
| pchar | prints the ASCII equivalent of the number at the top of the stack |
| pstr | prints the ASCII equivalent of the numbers stored in each element in the stack, starting from the top |
| rotl | rotates the top element of the stack to the bottom of the stack |
| rotr | rotates the bottom element of the stack to the top of the stack |
