Try this before running!

Try this code, valid/invalid and output:

#define Print(Exp) printf(#Exp" = %d", Exp)

void main()
{
int x = 3, y = 4;
Print(x/y);
}

&

void main()
{
int Arr[] = {1, 2, 3, 4, 5};
printf("%d", 2[Arr]);
}

Taken from some campus exam questions, so try to answer before you
execute.

output of

void main()
{
       int Arr[]  = {1, 2, 3, 4, 5};
       printf("%d", 2[Arr]);

}

it will print the element with index 2 of the array i.e. 3..
This is so because 2[Arr] is equivalent to *(2+Arr) i.e adding 2 to
the base address of array Arr and then calculating the value at that
address.

and please give me the solution of 1st question....

@Neha: thanx for the explanation! I never guessed it worked like
this....

But how does define directive evaluate?? Anyone?
