is it possible C program without main() fn

[harsh gupta]

actually tre is no way u can erite a c prog without main ..
now its jus abt bluffing ..

#include<stdio.h>
#define decode(s,t,u,m,p,e,d) m##s##u##t
#define begin decode(a,n,i,m,a,t,e)

int begin()
{
printf(" hello ");
}

this prog is encoding main into some other name (here it is "begin ")
## is a merging operator..


Is it correct.....

It is possible

you have to set the entry point as a function name(in this case "Begin") in the linker.

hi....... main() indicates the starting of a prgm..... it intimates the control statement to start execution from 'main()' statement......

It is not possible, since only from the main() function we are calling other functions.
