Answer / kk
Here is a basic sample which uses main as the entry point..
#include <stdio.h>
#define myProxyMain main
int myProxyMain()
{
printf("\nHello World !!");
getchar();
return 0;
}
Just note that at source level there is no main but once
preprocessing we still have the old main() method.. Which
means we still have the main method in the object module as
well as the executable..

Answer / niranjan vg
This is the other way you can use it.....
#include<stdio.h>
int hello();
_start()
{
_exit(hello());
}
int hello()
{
printf("\n \t\t\t\t\tHello World\n");
printf("\n \t \t \t Welome to C in Linux\n");
}

Answer / andy
Ranjan's answer was the correct one. And it's what interviewers expect.
use g++ to compile and run this:
#include<stdio.h>
#include<iostream>
class World
{
public:
World()
{
printf("Hello world\n");
}
};
World w1;
int main()
{
printf("Hello world again!!\n");
return 0;
}
