How to compile and run a C/C++ program on the Android system (like MinGW on the Windows)?

I want to compile and run the C/C++ program on the Android phone program (like G1).

For example, I write a "Hello World.c" program, then compile and run it on my Android phone system.

I have never used MinGW to run my code on my Windows system, so I also want to do it on the Android phone system.
