And who tells the program gives int(3) int(3)? I just wrote a program in C
which gave me 3 and 2,
#include stdio.h
int main()
{
int a, c;
a=1;
c=a+a+a++;
printf(%d\n,c);
a=1;
c=a+a++;
printf(%d, c);
}
This program prints 3 2 not 3 3

I would like to say something to reporter, i think that's a post increment
expression which will give int(3) int(3). That's not bug...

Expected result is int(3) int(2) I suggest you to read about pre and post
increment / decrement :p

Yep, there's a bug, but way of expressing is wrong, expected output is 3,2 but
gives you 3,3
