Please answer my Q

Question

#include <iostream>
using namespace std;
int main ()
[
int y,x,z;
y=x=z=1;
y= ++x + ++x + x++;
z - =x;
cout <<x<<y<<z;
return o;
]

Answer 1

Output is 4 9 -3
Because
First x is 1 then due to 2 pre increments
x becomes 3 and then
y=3+3+(3++)
So y is 9
And x becomes 4
Then z=z-x
Thus z is 1-4 that is -3
/*Note different compilers treat in different ways*/

Answer 2

x=1
y=8
z=0
