C语言中一个拥有n个元素的数组其下标范围是0到n-1却不是1到n,这种设计有什么优势吗?

对于i = 0; i < N和i = 1; i <= N的循环次数计数来说N - 0 = N次和N - 1 + 1 = N,前者是更直观的,详细见Dijkstra对此的解释:http://www.cs.utexas.edu/users/EWD/ewd08xx/EWD831.PDF

lua的下标为什么要从1开始? 反人类!

数组的下标应该从0还是1开始?我提议的妥协方案是0.5,可惜他们未予认真考虑便一口回绝。

a[i] == a + i;

@fantasticfears 这样的话就不必老纠结多1少1的问题了。
