如何在Prolog中做I = i + 1之类的事情 [英] How to do something like I = i+1 in Prolog

问题描述

我想这样做：



TotalPlayer = TotalPlayer + 1来计算我的功能的玩家总数。



但是prolog不允许更改变量的值。因为我认为在prolog中，一旦变量被绑定，我们就无法改变它的绑定。



那么我怎么能像我们一样将变量的值增加1在java做：i ++



我尝试过：

 TotalPlayer = TotalPlayer + 1。

解决方案

我建​​议从一开始就学习语言，也许 [ ^ ]。

I want to do this:

TotalPlayer = TotalPlayer + 1 to cal the total number of players for my function.

but prolog does not allow to change the value for the variable. Because I think in prolog, once a variable is bound, we can't change its binding.

So how can I increment the value of a variable by 1 like we do in java: i++

What I have tried:

TotalPlayer = TotalPlayer + 1 .

解决方案

I would suggest learning the language from the start, perhaps here[^].
