什么是iota的std :: iota代表？ [英] What does iota of std::iota stand for?

问题描述

我假设i是增量，a是赋值，但我无法找出或找到答案。此外，它看起来非常类似于非标准 itoa ，我认为是混乱。

I'm assuming the "i" is increment and the "a" is assign, but I could not figure out or find the answer. Also, it looks very similar to the non-standard itoa which I think is confusing.

推荐答案

从 http://www.sgi.com/tech/stl/iota.html：

名称iota取自编程语言APL。

The name iota is taken from the programming language APL.

在他的图灵奖演讲中，Ken Iverson（APL的发明者）说：

例如，ι integer c>在应用于参数 N 时生成第一个 N 整数的向量...

For example, the integer function denoted by ι produces a vector of the first N integers when applied to the argument N, …

这个有趣的字符是小写的希腊字母iota。我输入了ι， U + 03B9， GREEK SMALL LETTER IOTA，但是Unicode实际上对APL的iota有一个专用的代码点：⍳是 U + 2373，APL FUNCTIONAL SYMBOL IOTA。

That funny character is the lower-case Greek letter iota. I typed ι, U+03B9, "GREEK SMALL LETTER IOTA", but Unicode actually has a dedicated code point for APL's iota: ⍳ is U+2373, "APL FUNCTIONAL SYMBOL IOTA".
