预增量和后增量之间的差异 [英] Difference between pre-increment and post-increment

问题描述

x ++和++ x之间的区别;

x - 和 - x之间的区别;

Difference between x++ and ++x;
Difference between x-- and --x;

推荐答案

++ x是预增量和x ++是后增量，在第一个x中，在使用之前递增，在第二个x在使用之后递增。


这最容易用小程序

++x is pre-increment and x++ is post-increment that is in the first x is incremented before being used and in the second x is incremented after being used.

This is most easily demonstrated with a small program

展开 | 选择 | Wrap | < span class =codeLinkonclick =LineNumbers（this）;>行号

x - 和 - x之间的区别;

Difference between x-- and --x;

我原以为你可以修改我发布的程序找出，其中++是增量的 - 除了在类似庄园中的行为之外是减量。

I would have thought you could have modified the program I posted to find out, where ++ is increment -- is decrement, apart from that that act in a similar manor.
