Learn Fractal++

Step 1: Importing Modules

Example:

<^> ::= import io

Exercise:

Import the math module using the <^> syntax.

Step 2: Defining Constants

Example:

<#> ::= "Fractal++ is the best language!"

Exercise:

Define a constant named PI with the value 3.14159.

Step 3: Defining Functions

Example:

<$> ::= (msg) => {
    io.console(msg)
}

Exercise:

Define a function named greet that takes a parameter name and prints "Hello, [name]!".

Step 4: Recursive Functions

Example:

<@> ::= (n) => {
    if (n === 0) {
        return 1
    }
    return n * <@>(n - 1)
}

Exercise:

Write a recursive function named countDown that takes a number n as input and returns a string with the numbers from n down to 1 separated by newline characters (\n).

Step 5: Main Program

Example:

<&> ::= {
    let number = 5
    let result = <@>(number)
    math.print("Factorial of", number, "is", result)
}
<%> ::= () => <&>
<^>
<%>()

Exercise:

Write the main program that calculates and prints the sum of numbers from 1 to 10.

Congratulations!

You have learned the basics of Fractal++. Keep it up!
