This is a C programming group project, Algorithm and Data structure
Relied on unique stack.The goal of this project is to create an interpreter for Monty ByteCodes files
These are files containing Monty byte codes usually with 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.
julien@ubuntu:/monty$ cat -e bytecodes/000.m
push 0$
push 1$
push 2$
push 3$
pall $
push 4$
push 5 $
push 6 $
pall$
julien@ubuntu:/monty$
Monty byte code files can contain blank lines (empty or made of spaces only, and any additional text after the opcode or its required argument is not taken into account:
julien@ubuntu:~/monty$ cat -e bytecodes/001.m push 0 Push 0 onto the stack$ push 1 Push 1 onto the stack$ $ push 2$ push 3$ pall $ $ $ $ push 4$ $ push 5 $ push 6 $ $
- pall This is the end of our program. Monty is awesome!$ julien@ubuntu:~/monty$
- Usage: monty file where file is the path to the file containing Monty byte code
- If the user does not give any file or more than one argument to your program, print the error message USAGE: monty file, followed by a new line, and exit with the status EXIT_FAILURE
- If, for any reason, it’s not possible to open the file, print the error message Error: Can't open file , followed by a new line, and exit with the status EXIT_FAILURE where is the name of the file
- If the file contains an invalid instruction, print the error message L<line_number>: unknown instruction , followed by a new line, and exit with the status EXIT_FAILURE where is the line number where the instruction appears.
- Line numbers always start at 1
- The monty program runs the bytecodes line by line and stop if either: it executed properly every line of the file it finds an error in the file an error occured
- If you can’t malloc anymore, print the error message Error: malloc failed, followed by a new line, and exit with status EXIT_FAILURE. You have to use malloc and free and are not allowed to use any other function from man malloc (realloc, calloc, …)
