@@joelmartinez7326 tambien lo hace, el codigo esta escrito en forma de dona, no creas que es solo la forma. Es literalmente el codigo en C, lo pegas, y ejecutas y tienes una dona en 3d girando.
A classic! This is a PPM (Portable Pixel Map) animation program in C, written by John Hancock in 1986. It's a simple raycasting-based 3D graphics demo that uses ASCII art to display the scene. Here's a breakdown of what the code does: 1. Initialization: The program sets up some variables and arrays for storing pixel data. 2. Main loop: The program enters an infinite loop, where it repeatedly: * Clears the screen using ANSI escape sequences (`\x1b[2J`). * Sets up some mathematical constants (A, B, etc.). * Calculates the sine and cosine of various angles (i, j, A, B) using simple trigonometric formula formulas. * Uses these calculations to determine the pixel values (D, l, m, n) for a 2D grid. * Updates the pixel data array (z) and ASCII art string (b) based on the calculated values. 3. Output: The program prints the updated ASCII art using ANSI escape sequences (`\x1b[H`), followed by the `putchar` function to display each line of text. The animation is a simple, rotating 3D scene with some basic lighting and shading effects. The ASCII art rendering gives the appearance of a 2D projection of the 3D scene onto a plane. This code is a great example of the creativity and ingenuity that can be achieved with limited resources (in this case, early computing technology and the ASCII character set). It's also a testament to the enduring appeal of simple, yet engaging, graphical demonstrations.
🍩 wait. the syntax is cleverly arranged as the donut _AND_ it's unreadable? perfecto for beginners!! 🍩 or as my wise sensei would always say: "donut try to code the donut, before you have mastered the tao-nut."
Can anyone explain how this code is not erroneous? There's no declaration of standard libraries and the k variable is declared in the wildest way possible
C has a simpler syntax and less features while c++ is much more complex. In c it's easy to shoot yourself in the foot while in c++ it's harder to do so but if you shoot your leg comes off, imo syntax wise c is easier but in general c++ is easier

You can use anything. You can write in notepad and save it with a .c extension, and then use the terminal (if you have gcc compiler installed) and type: gcc -o outputfile inputfile I know you’re not asking about notepad, though. Most new developers pick something like VS Code, but Visual Studio Community is what I started C and C++ with.

it's a c program (typically an exe or whatever the operating system can compile to), they didn't code it themselves and you can find it online by just searching some keys

Because the main idea of the code is using maths to make the rotation and projection of a 3d object into a 2d surface(the screen). I didn't go through the code well. But I understand the main idea behind it. There is a blog by the creator that explain it.
python crashes whenever the indentation is slightly wrong and since the code is supposed to be donut shaped the first line would need to have a few indents whoch is literally impossible
@@grzyb11 I'm familiar with the Python indentation issues. That was why I made the comment. However, I think you are overstating the difficulty by saying it is impossible. Evan Zhou did a donut shaped Python donut a few months ago ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-tzpfyTFvU6M.html. Granted, it did have a leading line which ruins the pure donut shape and so a purist could easily discount it. However, I think that with copious use of # comments (which don't have to follow the indentation rules) preceding the first functional line, it might be possible.
