C++ is a general-purpose programming language created by Bjarne Stroustrup as an extension of the C programming language, or "C with Classes". The language has expanded significantly over time, and modern C++ has object-oriented, generic, and functional features in addition to facilities for low-level memory manipulation. Features: - Compile and run your program - View program output or detailed error - Choose between C++ compiler standards (ISO/IEC 14882) namely: C++98, C++03, C++11, C++14, C++17, C++20, C++23 - Multithreading support - 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/C++ 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.
