C# Programming Compiler vs One Grain

Write C# code directly on your iPhone, iPad and iPod Touch! This app is ideal for learning and testing code snippets! C# (pronounced C sharp) is a general-purpose, multi-paradigm programming language encompassing strong typing, lexically scoped, imperative, declarative, functional, generic, object-oriented (class-based), and component-oriented programming disciplines. It was developed around 2000 by Microsoft within its .NET initiative and later approved as a standard by Ecma (ECMA-334) and ISO (ISO/IEC 23270:2018). C# is one of the programming languages designed for the Common Language Infrastructure. Features: - Compile and run your program - View program output or detailed error - Custom keyboard for easy input of frequently used characters - Optimized for connecting with external physical/bluetooth keyboard - Advanced source code editor with syntax highlighting, bracket completion and line numbers - Open, save, import and share C# files. Limitations: - Internet connection is required for compilation - Maximum program running time is 20s - One file can be run at a time - Some file system, network and graphics functions may be limited - This is a batch compiler; interactive programs are not supported. For example, if your program provides an input prompt, enter the input in the Input tab prior to compilation.

One Grain, 一粟, is a Chinese character memorization app: a focused daily companion that helps Chinese learners build the one foundation everything else depends on: Chinese characters. In Chinese culture, the wisdom of "accumulating little by little" has always been deeply valued. The name "一粟", One Grain, carries that spirit: just as grains accumulate one by one to fill a bountiful granary, characters grasped one by one build the foundation for real reading ability. HOW IT WORKS One Grain is a focused learning reinforcement tool: designed to help Chinese learners memorize characters, strengthen vocabulary recognition, and gradually build the confidence to read without pinyin support. Each session follows a three-part structure: 1. CHARACTERS A spaced repetition system (SRS) schedules each character exactly when memory needs it — not too soon, not too late. Consistent review builds stable, lasting recall. 2. WORDS Low-pressure multiple choice questions connect individual characters to vocabulary — reinforcing recognition in context, without the anxiety of open-ended testing. 3. SENTENCES Every session ends with a complete sentence built from familiar characters. Not a test. A moment of proof: "I can read something real today." THE PROBLEM IT SOLVES Many Chinese learners reach a turning point when Pinyin is removed, and then quietly disengage. Not because they aren't capable. But because their character foundation was never built to hold the weight. When characters don't stick, reading feels impossible. Frustration sets in. Motivation fades. One Grain addresses this directly. Using spaced repetition science and a deliberately low-pressure experience, it helps learners memorize characters systematically, reducing the fear, rebuilding the confidence, and laying the solid foundation that makes all other aspects of Chinese learning possible. DESIGNED FOR LEARNERS · Anyone learning to read Chinese characters · Students who struggle when Pinyin is removed · Learners who want a calm, consistent daily habit · Parents looking for a quiet supplementary tool Sessions run 5–15 minutes. Choose your pace. The algorithm handles the rest. 今日一粟。One grain, one step.
