C4Droid
It is a powerful offline C/C++ IDE + C/C++ compiler for Android operating System. I have been using it for 1 year. You do not need to root your phone to use this app. Its features are as listed below:
Information about resetting and configuring Mobile phones (Java, Android, Symbian etc), educational articles especially for programming in C, C++ and Java and more about Computers and operating systems
