Answer / naendra allam
Asume abc.c is the program
--------\abc.c\---------
#include <stdio.h>
#include <stdlib.h>
int naren()
{
printf("Hi--- Ther is no main() here.\n");
exit(EXIT_SUCCESS); //Not supposed to use 'return 0;'
}
-----------------------
//compilation with GCC
$gcc -c abc.c
---> which generates abc.o
$ld --dynamic-linker /lib/ld-linux-so.2 -oabc abc.o -enaren
-lc
---> which generates executable 'abc'
$./abc

Answer / narendra allam
We can write a Program without main() function in C-language.
There should be one entry point in the program, so we need a
function to satrt with. In linker scripts it is mentioned,
we can change it through -e option for 'ld' linker with gcc.
