Example

A simple Frut program that calculates factorials:

import std.io.*;

// Calculate factorial of a number
func factorial(n: int): int {
    if n <= 1 {
        return 1;
    } else {
        return n * factorial(n - 1);
    }
}

// Calculate and print factorial of 5
var result: int = factorial(5);
println("Factorial of 5 is: " + result as string);

Save this as factorial.ft and run:

frut factorial.ft
