C4droid already has almost full C language support, so you don't need to wait when it will be added.
You can to write your own applications on Android phone, and run them. This app uses TCC and uClibc, so it has full support of ANSI C and some support of ISO C99. C4droid can be used for educational purposes or to practice in C language.
Some components of C4droid are LGPL-licensed. You can download used source code of TCC and uClibc on their websites (But TCC had been modified by me, so I recommend to email me to get modified source).
C4droid includes Android Terminal Emulator so you can to run your application comfortably.
To get C++ support you need:
1) Install GCC plugin (C4droid will ask you to install it).
2) Select G++ compiler in C4droid preferences.
3*) Use iostream, not iostream.h
4*) Add "using namespace std;" to your program (before int main)
To compile Makefile projects, open any file in the same folder with Makefile and long-click "Compile" to configure current directory (C4droid will create .c4droid configuration file when you'll press Ok). After configuring folder, you can press compile button and C4droid will build your project.
Don't forget to enter executable name and select compilation mode (and press ok also, else changes will be discarded)
C4droid supports SDL, NativeActivity and Qt for GUI now, install SDL plugin for C4droid to use it (only GCC/G++ compiler is supported, so you need GCC plugin).
(SDL is detected with #include "SDL.h", NativeActivity is detected with #include "android_native_app_glue.h", Qt is detected with #include "QtGui").
There is an experimental support for Qt using necessitas, but note that it's in alpha stage.
Qt support limitations:
1) Path to Ministro libraries is hardcoded (/data/data/org.kde.necessitas.ministro/files/qt/lib), so email me if it will change.
2) Only QtCore and QtGui libraries are supported by C4droid for now.
3) If you're compiling a single-file Qt app, you must add #include "yoursourcefilenamewithcpp.moc" to the end of file. If you're using .pro file for compilation, you don't need to do that.
Quick manual:
If you have found a bug or app is not working, email me.
If app crashes on start, reboot your device, it's a Google Play/Android bug.
Long click save button to "save as", long click run to run with arguments.
Result of compilation (binary) is placed in "/data/data/com.n0n3m4.droidc/files/temp", because sdcard doesn't have permission for execution by default.
If you have "Illegal instruction" error, using internal compiler (TCC), install GCC plugin, GCC supports softfloat (by default).
