simple stack based Virtual machine

build 

clone the repo and fire the make command

changing the program 

to change the program edit the
 


```c

int program[] = {

PSH, 15,

PSH, 3,

DIV,

HLT,

//the stack pointer must pointing to value 5 

};

```

Note the program is array so dont forget to put , after every instructions


instruction set 


Operation | Description

------ | ------ 

PSH   | pushes the value to the top of the stack

POP   | pops the value , now the stack pointer points to the previous value

ADD   | Adds the the top two values and pushes them

SUB   | substracts the the second value from the previous

MUL   | multiples top two values on the stack

Div   | divides the top value by the first second top value

AND   | does the binary AND operation and on the top two value

OR    | does the binary OR operation and on the top two value

HLT   | Marks the end of the program
