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

Why n++ execute faster than n+1 ?
