Code Sample Descriptions

Hello World in Piet

[Piet programs are images, not text - this would be a bitmap of color regions spelling out 'Hello World!']

A Piet 'Hello World!' program is an image composed of colored blocks. The code below is just a placeholder; actual execution requires an interpreter that processes the image.

Let’s Try →

Print 'Hi' in Piet

[Piet programs are images, not text - this image would contain color regions that output 'Hi']

A Piet program to output 'Hi'; represented as an image.

Let’s Try →

Simple Counter in Piet

[Piet programs are images, not text - this image would have regions representing the counting logic]

A Piet program that counts from 1 to 5 and prints numbers.

Let’s Try →

Print Digits 0-9 in Piet

[Piet programs are images, not text - color blocks represent sequential digits output]

A Piet program to print digits 0 through 9.

Let’s Try →

Simple Loop in Piet

[Piet programs are images, not text - image would contain loop with directional pointer changes]

Demonstrates a looping construct using Piet's directional transitions.

Let’s Try →

Print Alphabet A-Z in Piet

[Piet programs are images, not text - each letter represented via color transitions]

Prints uppercase letters A-Z using color-coded instructions.

Let’s Try →

Fibonacci Sequence in Piet

[Piet programs are images, not text - blocks represent arithmetic operations to produce Fibonacci numbers]

Generates a short Fibonacci sequence as output.

Let’s Try →

Print 'Bye!' in Piet

[Piet programs are images, not text - image contains color regions encoding 'Bye!']

Outputs 'Bye!' as a demonstration of Piet program flow.

Let’s Try →

Simple Arithmetic in Piet

[Piet programs are images, not text - arithmetic simulated via color changes]

Performs arithmetic operations and prints results.

Let’s Try →

Nested Loop Output in Piet

[Piet programs are images, not text - nested loops achieved through color pointer navigation]

Demonstrates nested loops producing sequential output.

Let’s Try →
