    Here's a C programming challenge: Can you write a C program without main()? If yes, post your code below and I will take a look.

    Can you write a C program without main() ??
    We had a similar thread for JAVA.
    Check : #-Link-Snipped-#

    It is quite possible to write a C program without main() if we know how to use preprocessor and macro.
    Are you sure? This action cannot be undone.

    This is actually the solution. Yes, we can write a program without main logically but it is not possible conceptually..
    Here is the program:

    #include<stdio.h>
    #include<conio.h>
    #define decode(a,u,d,i,b,l,e) i##a##d##u
    #define START decode(a,n,i,m,a,t,e)
    void START()
    {
    clrscr();
    printf("Hey this is Nick waving hi from a program without main");
    getch();
    }
