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 a post incremented and assigned to itself in one statement? I compiled and executed this. x is still 7 even after the entire statement. In my book, it says that x is incremented!

Answer 1

x acts become incremented. But you are allowing the old value of x rear toward itself.

x = x++;

• x++ increases x and delivers its old value.
• x = indicates the old value posterior to itself.

So in the finish, x gets allocated terminal to its primary value.
