Go Programming Compiler vs RubyLearn

Write Go code directly on your iPhone, iPad and iPod Touch! This app is ideal for learning and testing code snippets! Go (incorrectly known as Golang) is a statically typed, compiled programming language designed at Google. Go is syntactically similar to C, but with memory safety, garbage collection, structural typing and CSP-style concurrency. 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 Go files. Supports File Sharing with iTunes Connect, AIrDrop and iCloud. - Language reference 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.
