The Monty Bytecode Interpreter is a program that reads and executes Monty bytecode files.
To run the Monty Bytecode Interpreter, use the following command:
./monty file
where file is the path to the Monty bytecode file you want to execute.
The Monty bytecode language supports the following instructions:
push <value>: Pushes an integer value 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: Does nothing....(more instructions)
Additional instructions may be added to the language in the future.
Here is an example Monty bytecode file that adds two numbers:
push 1$
push 2$
push 3$
pall$
Running this file with the Monty Bytecode Interpreter will output:
3
2
1
The Monty Bytecode Interpreter includes error handling for the following cases:
- Invalid instructions: If an unknown instruction is encountered, an error message will be displayed with the line number and the unknown instruction. The interpreter will exit with a failure status.
- File opening failure: If the specified bytecode file cannot be opened, an error message will be displayed. The interpreter will exit with a failure status.
The Monty Bytecode Interpreter is implemented in C programming language. The main functionality is contained in the process_file.c file. Additional helper functions and data structures are defined in separate files.
To build the Monty Bytecode Interpreter, use the following command:
gcc -Wall -Werror -Wextra -pedantic *.c -o monty
This will compile all the necessary source files and generate an executable named monty.
