而在较小程度上,与i<(n+1)的 lo体有何关系? (n+1)在 lo开始或每 it一次得到评估吗?
for(int i=0; i<(n+1); i++){
// Do something
}
for(int i=0; i<=n; i++){
//Do something
}
UPDATE:
As suggested by nearly everyone, I ran a simple test with three loop variations i

这很可能取决于是否在休息期间改变了N的价值。 否则,我想,任何现代汇编者都会拿到N+1的数值,而不是计算每 it。 当然,如果没有保证,并且没有优化,则每次都要评估N+1 。
www.un.org/Depts/DGACM/index_spanish.htm 回答标题问题,i < n vs. i <= n不会有明显差异(除了额外的外,假设这两个案件中的ns平等)。 CPU有两种比较的单一机会。
我确实怀疑,这将在预案执行中产生可衡量的区别。 特别是<
vs <=
。 如果你真心关切的话,请,。
这是一种具体的汇编,没有语言标准对此加以界定,尽管大多数汇编者将努力达到价值(如果证明是无所作为的话)。
委托汇编者。 即便是C#汇编者+联合执行 Ter并不像最佳的++编纂者那样好,但它仍然很好。 除非你以大概者的身份确定,它正在造成一个问题,否则你就没有花周期来担心这些类型的微型刺激。 相反,写的是与你做些什么合乎逻辑。
