~~~ Compiler for PL/0 ~~~

1. Compile the C file:
    gcc compiler.c

2. Run it:
    ./a.out input.txt 

    ~~ It takes 1 command line argument (EX: input.txt) ~~
    ~~ It it prints to the console (stdout), and creates ~~
    ~~ an "elf.txt" file with purely VM numberical code" ~~

3. Output prints to console + elf.txt is generated

    ~~ This "elf.txt" is what is then used as a command ~~
    ~~ line argument into my VM (HW1). Note there is no ~~
    ~~ ODD instruction. At the time it wasn't reqired. ~~

4. NOTE! (IMPORTANT requirement): 

    ~~ Your input PL0 source code, cannot start the with ~~
    ~~ the leading whitespace. i.e. the very first PL0 code ~~
    ~~ character must be the start of your code, and NOT a ~~
    ~~ stream of whitespaces ~~

5. Unit Test test cases:
    ./test.sh
    
    ~~ If doesnt run, adjust shebang (top comment) ~~
    ~~ if needed by typing "which bash" in terminal ~~
    ~~ and placing it's output on the first line ~~
    ~~ instead of /bin/bash. Also give yourself the ~~
    ~~ executable permissions by typing the command ~~
    ~~ "chmod +x test.sh". The scripts execusion is ~~
    ~~ to automatically compile my C source file and ~~
    ~~ to run through my extra 67 .txt test cases ~~
    ~~ All of them must be in the same directory ~~
    ~~ Format of .txt's: inX.txt (input), baseX.txt ~~
    ~~ (what correct output must normally be), and ~~
    ~~ (outX.txt what the actual output is), where X ~~
    ~~ is the number of the test case (ex: 1, .. ,67)~~
    ~~ If all my extra test cases passed, my scripting~~
    ~~ program will output to console the following: ~~
