RPN Calculator in OCaml - A Tutorial
Introduction
Reverse Polish Notation (RPN) is a mathematical notation where operators are placed after the numbers they operate on, instead of in between them. In this tutorial, we will learn how to create an RPN calculator using OCaml - a free and open-source programming language.What is OCaml?
OCaml is a high-level, statically-typed programming language that supports functional, imperative, and object-oriented programming paradigms. It provides advanced features such as garbage collection, type inference, and pattern matching.The Basic Algorithm
To create an RPN calculator, we need to follow a few basic steps:- Start with an empty stack.
- For each token in the input expression:
- If the token is a number, push it onto the stack.
- If the token is an operator, pop the top two values off the stack, apply the operator, and push the result back onto the stack.
- The final answer is the only value left on the stack.
Implementing the Algorithm in OCaml
Let's start by defining a stack data structure. We can use a list to represent the stack, where the first element in the list is the top of the stack. type stack = int list
let rec evaluate stack tokens = match tokens with | [] -> List.hd stack | tok::t -> match tok with | '+' -> evaluate ((List.hd stack + (List.hd (List.tl stack)))::(List.tl (List.tl stack))) t | '-' -> evaluate ((List.hd stack - (List.hd (List.tl stack)))::(List.tl (List.tl stack))) t | '*' -> evaluate ((List.hd stack * (List.hd (List.tl stack)))::(List.tl (List.tl stack))) t | '/' -> evaluate ((List.hd stack / (List.hd (List.tl stack)))::(List.tl (List.tl stack))) t | _ -> evaluate ((int_of_string tok)::stack) t;;
Testing the Calculator
Now that we have our RPN calculator implemented, let's test it with some simple expressions. let expr = 3 4 + in print_int (evaluate [] (String.split_on_char ' ' expr))
let expr = 5 3 - in print_int (evaluate [] (String.split_on_char ' ' expr))
Adding More Operators
To add more operators to our RPN calculator, simply add more cases to the `match` statement. For example, to add a power operator (`^`), we can modify the function as follows: let rec evaluate stack tokens = match tokens with | [] -> List.hd stack | tok::t -> match tok with | '+' -> evaluate ((List.hd stack + (List.hd (List.tl stack)))::(List.tl (List.tl stack))) t | '-' -> evaluate ((List.hd stack - (List.hd (List.tl stack)))::(List.tl (List.tl stack))) t | '*' -> evaluate ((List.hd stack * (List.hd (List.tl stack)))::(List.tl (List.tl stack))) t | '/' -> evaluate ((List.hd stack / (List.hd (List.tl stack)))::(List.tl (List.tl stack))) t | '^' -> evaluate (int_of_float ((float (List.hd (List.tl stack))) ** (float (List.hd stack)))::(List.tl (List.tl stack))) t | _ -> evaluate ((int_of_string tok)::stack) t;;
Note:
We used `int_of_float` to convert the result of `(float (List.hd (List.tl stack))) ** (float (List.hd stack))` to an integer.Conclusion
In this tutorial, we learned how to create an RPN calculator using OCaml. We started by defining a stack data structure, and then implemented the basic algorithm as a recursive function. Finally, we added more operators to our calculator.The Beauty of RPN Calculator in Ocaml
