Yes it is possible to run a c program with out main for this
you need to supply astart(assembly procedure CRT) address in
the command line.

no

Thanx elahi....

in linux while compilation we u mention -nostartfiles it 
will work
#include<stdio.h>
abc()
{
    printf("hello");
}

Hi Valli,

I tried the solution provided by you. It doesnot work. 

Please chk the compliation procedure.
gcc -g -nostartfiles main.c


I am getting the following: 
/usr/bin/ld: warning: cannot find entry symbol _start;
defaulting to 080481a4

just compile as
cc -nostartfiles main.c
