C++ Design Pattern: What is a Design Pattern? C++ Design Pattern: What is a Design Pattern? Q: What is a Design Pattern?A: Design Patterns represent solutions to problems what arise when developing software within a particular context. Each pattern describes a problem which occurs over and over again in our environment, and then describes the core of the solution to that problem, in such a way that you can use this solution a million times over, without ever doing it the same way twice.C. Alexander, The Timeless Way of Building, 1979 Patterns help you learn from other's successes, instead of your own failures.Mark Johnson (cited by Bruce Eckel) Q: How many types of design patterns exist?A: Basically, there are three categories: Creational Patterns: deal with initializing and configuring classes and objects Structural Patterns: deal with decoupling the interface and implementation of classes and objects Behavioral Patterns: deal with dynamic interactions among societies of classes and objects
Memory Snapshot for a Process In-depth memory layout is specific to both the CPU architecture and the OS itself. I'm going to describe how a process sees its own memory share during execution. Memory Layout from a process perspective Memory Snapshot for a Process

Tree traversal Tree traversal In computer science, tree traversal (also known as tree search) refers to the process of visiting (examining and/or updating) each node in a tree data structure, exactly once, in a systematic way. Such traversals are classified by the order in which the nodes are visited. The following algorithms are described for a binary tree, but they may be generalized to other trees as well. Types[edit] Pre-order: F, B, A, D, C, E, G, I, H In-order: A, B, C, D, E, F, G, H, I
Converts between types using a combination of explicit and implicit conversions. [edit] Syntax Returns a value of type new_type.

Floating Point Numbers Floating Point Numbers by Jeff Bezanson Numbers are surely the most prevalent kind of data in computer programs. They are so fundamental that people don't spend much time talking about them—surely everybody knows how to use numbers in their programs. Well, one of the wonderful things about programming is that nearly everywhere you look, you find more than meets the eye. Most programmers have heard or observed one strange thing or another about floating point numbers. For example, we often discover that floating point numbers that look the same do not necessarily satisfy C's "==" test.
