Answer / sushil kumar
Well Done !!!!!!!
I can give an explanation
When a c program is compiled the preprocessor process the code and replace the macros in the code
IN void rawat()
#define rawat ravinder(m,b,a,j,n,i) replaces rawat so code becomes
void ravinder(m,b,a,j,n,i)()
which calls the first macro to replace ravinder(m,b,a,j,n,i) by m##a##i##n i.e main
so now we have
void main()
that's why this code executes correctly
C always requires a main program to execute

Answer / himanshu
ans 13 is not totally right!
you see you have used main straight away.
you aren't supposed to use main any where in the code.

Answer / himanshu rajput
Sushil kumar is right.exactly this is being happened in that program.That program is also using main function by the reference of other name.so c program always requires main function and does'nt have any mean without main.
but we do'nt need to write clrscr() and getch() function to our program in latest compilers like as DEV-C++.
