Cxxdroid is the most easy to use educational C and C++ IDE for Android.

Features:
- Offline C/C++ compiler: no Internet is required to run C/C++ programs.
- Package manager and a custom repository with prebuilt packages for common libraries, such as Boost, SQLite, ncurses, libcurl, etc.
- Graphics libraries such as SDL2, SFML* and Allegro* are also available.
- Examples available out-of-the-box for quicker learning.
- Full-featured Terminal Emulator.
- C/C++ interpreter mode (REPL) based on CERN Cling is also available.
- Outstanding performance with advanced compiler caching technology: upto 33 times faster when Boost library is used, 3x average speedup.
- Clean and mature architecture: now code is analyzed and compiled with the same compiler, and the IDE doesn't crash completely due to runtime errors in your programs :)
- UI designed with speed and usability in mind: forget about unobvious shortcuts or touch button combos required just to run your program.
- True compiler: no Java (or even Javascript) based interpreters involved, even inline assembler language is supported (Clang syntax).

Editor features:
- Real time code prediction, auto indentation and code analysis just like in any real IDE. *
- Extended keyboard bar with all symbols you need to program in C++.
- Syntax highlighting & themes.
- Tabs.
- One click share on Pastebin.

* Features marked by asterisk are available in Premium version only.

Important notice: Cxxdroid requires at least 150MB free internal memory. 200MB+ is recommended. More if you are using heavy libraries such as Boost.
