问题描述
可能重复：结果
的
首先code：
if(i==0) {// do instructions here}
二code：
if(0==i) { // do instructions here }
有什么块之间的区别？
What is the difference between the blocks?
推荐答案
在功能上，是没有区别的。结果
一些开发商preFER写第二格式，以避免错别字分配（如果你错过了一个 = ），所以错字的编译器警告。结果
二是著名的被称为
Functionally, there is no difference.
Some developers prefer writing the second format to avoid assignment typos(in case you miss a =), so that compiler warns of the typo.
The second is famously known as Yoda Condition.
我说没有差别，因为，你不能守护自己对每一个微小的细节，并依靠编译器来放声哭了你。如果你打算写一个 == 你应该期望自己写 == ，而不是 = 。结果
采用第二种格式只是导致一些不起眼的非可读code。结果
此外，大多数主流的编译器警告的分配的错字的通过 一旦启用所有的警告（你应该反正）。
I say there is no difference because, you cannot guard yourself against every minuscule detail and rely on compiler to cry out aloud for you.If you intend to write a == you should expect yourself to write a == and not a =.
Using the second format just leads to some obscure non-readable code.
Also, most of the mainstream compilers warn of the assignment instead of equality typo by emitting an warning once you enable all the warnings(which you should anyways).
