声明一个常量数组 [英] declare a constant array

问题描述

我曾尝试：

const ascii = "abcdefghijklmnopqrstuvwxyz"
const letter_goodness []float32  = { .0817,.0149,.0278,.0425,.1270,.0223,.0202, .0609,.0697,.0015,.0077,.0402,.0241,.0675, .0751,.0193,.0009,.0599,.0633,.0906,.0276, .0098,.0236,.0015,.0197,.0007 }
const letter_goodness  = { .0817,.0149,.0278,.0425,.1270,.0223,.0202, .0609,.0697,.0015,.0077,.0402,.0241,.0675, .0751,.0193,.0009,.0599,.0633,.0906,.0276, .0098,.0236,.0015,.0197,.0007 }
const letter_goodness = []float32 { .0817,.0149,.0278,.0425,.1270,.0223,.0202, .0609,.0697,.0015,.0077,.0402,.0241,.0675, .0751,.0193,.0009,.0599,.0633,.0906,.0276, .0098,.0236,.0015,.0197,.0007 }

首先声明和初始化工作正常，但第二，第三和第四不起作用。
我如何声明和初始化彩车的常量数组？

First declaration and initialization works fine, but 2nd, 3rd and 4th don't work. How can I declare and initialize const array of floats?

推荐答案

数组是不是天生一成不变的，你不能让它保持不变。

An array isn't immutable by nature, you can't make it constant.

你可以得到最近的是

var letter_goodness  = [...]float32 { .0817,.0149,.0278,.0425,.1270,.0223,.0202, .0609,.0697,.0015,.0077,.0402,.0241,.0675, .0751,.0193,.0009,.0599,.0633,.0906,.0276, .0098,.0236,.0015,.0197,.0007 }
