问题描述

What will be the values of X and y after executing the following expressions:
int x=20,y=35;
x=y++ + x++;
y=++y + ++x;

我的尝试：



我发现X的值为55，y为57，但我不确定它是否正确。

What I have tried:

I have found the value of X as 55 and y as 57 but I'm not sure if it's correct.

推荐答案

Quote：

我发现X的值为55，y为57，但我不确定它是否正确。

I have found the value of X as 55 and y as 57 but I'm not sure if it's correct.

我同意55，但不是57.

当计算新y时，x已经改变了。



知道答案的简单方法是制作程序并执行。

I agree with 55, but not with 57.
When the new y is calculated, x have changed already.

The easy way to know the answer is to make a program and execute.
