I++ 与 ++i 的主要区别有两个： 1、 i++ 返回原来的值，++i 返回加1后的值。 2、 i++ 不能作为左值，而++i 可以。 毫无疑问大家都知道第一点（不清楚的看下下面的实现代码就了然了），我们重点说下第. Modifying a value twice in the same expression (in this case your two ++i's) is undefined in both c and c++ and you cannot rely on its behavior to be the same across compilers. The way for loop is processed is as follows 1 first, initialization is performed (i=0) 2 the check is performed (i < n) 3 the code in the loop is executed.

Could someone explain in the simplest terms, as if you are talking to an idiot (because you are), what this code is actually saying/doing for (int i = 0;
In c, what is the difference between using ++i and i++, and which should be used in the incrementation block of a for loop?
Facebook's html and twitter bootstrap html (before v3) both use the <i> However, from the html5 spec: The i element represents a span of text in an alternate voice or m. There's absolutely no reason not to, and if.
I＝1，为什么 (++i)+ (++i)＝6？我觉得应该等于 2＋3＝5。 所以 (++i)+ (++i)+ (++i) = 10 是有可能的，但你真的很难预计编译器在背后做了什么。 你可以用反汇编去了解，但在未反汇编之前，你无法估计.
