问题描述
执行此操作后会发生什么（幕后）？
What happens (behind the curtains) when this is executed?
int x = 7;
x = x++;
也就是说，当一个变量后期递增并在一个语句中赋值给自己时？我编译并执行了这个。即使在整个声明之后， x 仍然是7 。在我的书中，它说 x 增加了！
That is, when a variable is 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!
推荐答案
x 确实会增加。但是你将 x 的旧值分配回自身。
x does get incremented. But you are assigning the old value of x back into itself.
x = x++;
-
x ++增量x并返回其旧值。 -
x =指定旧的价值回归自身。
x++incrementsxand returns its old value.x =assigns the old value back to itself.
所以最后， x 被分配回来到它的初始值。
So in the end, x gets assigned back to its initial value.
