This example contrasts the most basic inheritance pattern in C and C++ by displaying side-by-side source code. It shows how C++ uses virtual functions and classes to achieve runtime polymorphism, while C relies on manual vtable structs and function pointers to mimic the same behavior. The visualization highlights the structural differences in API design, such as C++’s `virtual` keyword and `class` syntax versus C’s explicit `Animal_vtable` and cast function pointers. The code’s output—identical for both languages—is implied through the `printf` and `cout` calls, but no rendering library is used; the data is the source itself.

C++ abuse: simple example

This example demonstrates the dangerous consequences of low-level memory manipulation in C++, where swapping an object’s vtable pointer with another object’s changes its runtime behavior. The code uses raw `void*` casts and pointer arithmetic in the `transmigrate` and `brain_damage` functions to overwrite the virtual function table entries of a `Dog` object with those of a `Cat`, causing the program to call the wrong virtual methods. The output sequence—showing `Dog::food()` initially, then `Cat::food()` after the swap, and finally undefined behavior after the vtable corruption—illustrates how such manual pointer juggling bypasses type safety and virtual dispatch. The example relies solely on standard C++ features like virtual functions, inheritance, and explicit pointer casts, with no external libraries.

Holding for inheritance work

This example demonstrates JavaScript class inheritance and object-oriented programming concepts using a Dog and Animal class hierarchy. The code defines constructors, prototype methods like `bark()` and `cuddle()`, static methods, getters, and setters, showcasing how instance properties and computed values work. It extends an Animal base class with a Dog2 subclass using `super()` to initialize inherited properties. The example also includes commented-out template rendering code referencing Nunjucks and Handlebars libraries, though no data visualization or rendering is actively executed in the final output.

This visualization uses a single file of JavaScript notes to map three inheritance patterns in Douglas Crockford’s code—pseudoclassical, prototypal, and functional—as a branching, node-link diagram. The code renders each pattern as a cluster of objects and functions, with edges showing prototype chains and constructor relationships. It relies on native JavaScript APIs like `Object.create` and constructor functions, while the layout is drawn on an HTML canvas without external libraries. The source is a gist by DylanFM, and the visual emphasizes the structural differences between the patterns by positioning them in separate columns.

This example demonstrates a simple class definition in C#. A single class, `A`, contains a string field named `name`, with no constructors, methods, or inheritance shown. The visualization uses no external libraries or rendering APIs, presenting the code structure directly as plain text. The data source is the Gist file `test.cs`, and the rendering approach is limited to displaying the raw source code without any graphical or interactive elements.

This example visualizes Ruby method lookup by displaying the ancestor chain for a given class and method. It shows the hierarchy of `Array < Enumerable < Object < Kernel` and highlights which ancestors define the queried method, using plain text output. The code relies on Ruby’s reflection APIs, including `ancestors`, `instance_methods`, and `singleton_methods`, to inspect class relationships. It prints a search log that marks each ancestor as defining the method as an instance or singleton method, or not at all, making the inheritance behavior explicit.

This example demonstrates object-oriented JavaScript patterns for modeling zoo animals, showing how constructor functions and prototypes create shared behavior. The code defines an `Animal` constructor with `identify()` and `name()` methods on its prototype, while a `Zoo` object manages collections of animals. Although the zoo methods contain incomplete logic, the driver code tests animal identification, leg counts, and prototype method sharing across instances. The example uses plain JavaScript—no external libraries—relying on `console.log` for output and a custom `assert` function for validation. It illustrates inheritance and code reuse, though the zoo aggregation methods remain non-functional as written.

This example demonstrates a C++ program that first simulates traversal and deletion of nodes in a singly linked list, printing the values as it moves and removes each node, and then reads a board from the file `board.txt` into a 2D vector of characters. The rendering shows the board as a grid, printing each cell with its indices and value, and then updates two specific positions to display a modified board. The code relies on standard C++ libraries such as `<iostream>`, `<fstream>`, and `<vector>`, with no external visualization APIs.

C++ Coding Standards

This visualization compares the content and structure of four Markdown documents detailing C++ coding standards, sourced from a gist by IoTeacher. It presents the documents as a series of colored blocks, with each block representing a section or paragraph, allowing for a side-by-side comparison of the documents' lengths and organizational flow. The layout is static, with no interactive elements, and the rendering likely uses a simple HTML/CSS grid or flexbox layout to display the document blocks. The visualization shows the proportional size of each document's sections, such as "Automated Code Analysis," "Style," "Performance and Safety," and "References," at a glance.
