What is x after “x = x++”?

Question

What happens (behind the curtains) when this is executed?

int x = 7;
x = x++;

That is, when a variable is post incremented and assigned to

Answer 1

So this means: x++ is not equal to x = x+1

because:

int x = 7; x = x++;
x is 7

int x = 7; x = x = x+1;
x is 8

and now it seems a bit strange:

int x = 7; x = x+=1;
x is 8

very compiler dependent!
