我如何在Haskell中的函数中重新分配一个变量？ [英] How can I re-assign a variable in a function in Haskell?

问题描述

例如，

函数x =大象= x


为什么这不起作用？

解决方案

Haskell是一个很棒的限制性的语言，并编写可以重新分配状态的程序是一个非常有趣的高级话题！这绝对不是你现在想要的方法，但有一天会回来

I don't know how to re-assign a variable in a function.

For example,

elephant = 0

function x = elephant = x

Why doesn't this work?

解决方案

Haskell is a great imperative language, and writing programs that can re-assign state is a really fun advanced topic! This is definitely not the approach you want right now, but come back to it some day
