nearly Each Linux Distribution is shipped with GNU Compiler Collection (gcc) and I thinkg it would be the best choice to use to compile your C program.
should compile simple c program. If you have more complicated application it should have a makefile. You will need to modify this makefile for your needs.
Goto Start->System Tools->Terminal & press enter
use command
gcc -c sachin.o(output file) sachin.c(input File)
or for an executable file
gcc -c -o sachin.exe sachin.c
There is a compiler. type "cc --help" or "cc (file name).c" and see what happens,
nearly in Each Linux there is GNU Compiler Collection (GCC) try to use Compile C programs that is best one.
