In the emulator I want to add the my C file and test the output file

take a example test.c after compile it will output file test

I have to run like
/>./test //in the emulator
//It will output is like
hello world

How can I do that?.

Is there possible to compile c file inside emulator

Can anyone give me solutions.

Thanks in advance
