为什么叫iota? [英] Why is it Called iota?

问题描述

C ++ 11引入了一个名为 iota .

C++11 introduced a function called iota. Which "Assigns to every element in the range [first,last) successive values of val, as if incremented with ++val after each element is written."

有人可以在这里解释"iota"是什么意思吗?

Can someone explain what "iota" means here though?

我查找了"iota" ，它似乎与生成范围无关

I looked up "iota" and it seems to have nothing to do with generating a range.

推荐答案

引用此非权威但仍然正确的wiki:

Quoting this non-authoritative, but nonetheless correct, wiki:

该函数以编程语言APL中的整数函数⍳命名.

在APL中，⍳函数(用希腊字母的第九个字母iota表示)用于创建从零开始的，连续的，指定长度的整数的数组.

In APL, the ⍳ function (represented with the ninth letter of the Greek alphabet, iota) is used to create a zero-based array of consecutive, ascending integers of a specified length.
