生成随机字母表,其中一些字母表出现频率较高(vc++6.0)
基本上我有一个生成随机字母的函数。我已经使用 rand() 函数生成数字,并将它们转换为相应的 ascii 等效项。 但我希望与其他字母相比生成更多的元音。 如果生成了 10 个字母,那么应该有 2 个 o、3 个 a 等。 我该如何做到这一点?在vc++6.0中。
编辑: 实际上我正在用 vc++6.0 制作拼字游戏作为我的大学项目。所以在我的板下我有 7 个按钮,每个按钮上我显示一个随机字母。所以我想要的是......就像在拼字游戏中我们有:
1 point: E ×12, A ×9, I ×9, O ×8, N ×6, R ×6, T ×6, L ×4, S ×4, U ×4
2 points: D ×4, G ×3
3 points: B ×2, C ×2, M ×2, P ×2
4 points: F ×2, H ×2, V ×2, W ×2, Y ×2
5 points: K ×1
8 points: J ×1, X ×1
10 points: Q ×1, Z ×1
所以就像你从上面描述的集合中选择 7 个随机字母一样,我想要以同样的方式生成 7 个字母。
basically i have a function that generates random alphabets .i have done this using the rand() function to generate numbers and them converted them to their corresponding ascii equivalents.
but i want the vowels to be generated in higher numbers as compared to other alphabets.i.e
if have generated say 10 alphabets then there should be like 2 o's,3 a's etc.
how do i do this??in vc++6.0.
Edit:
actually i am making scrabble as my college project in vc++6.0. so under my board i have 7 buttons on which i am displaying a random letter on each.so what i want is that ..like in scrabble we have:
1 point: E ×12, A ×9, I ×9, O ×8, N ×6, R ×6, T ×6, L ×4, S ×4, U ×4
2 points: D ×4, G ×3
3 points: B ×2, C ×2, M ×2, P ×2
4 points: F ×2, H ×2, V ×2, W ×2, Y ×2
5 points: K ×1
8 points: J ×1, X ×1
10 points: Q ×1, Z ×1
so just like you would pick 7 random letters from the above described set, i want the 7 letters to be generatd in the same way.

您可以添加另一个 rand 函数。
Fe(抱歉,这只是伪代码)
这将以 50/50 的几率生成元音,您可以通过更改 5.
Bobby来更改此几率
You could add another rand function.
F.e. (sorry, this is just pseudo code)
This will generate vowels at a 50/50 chance, you can change this chance by altering the 5.

给每个值一个权重。例如a = 5,b = 5,c = 2,... q = 1,z = 2等
权重越高,您越希望字母出现
计算随机字母,将所有权重加在一起并在 0 和总重量之间随机选择一个。
然后选择与抽出的数字对应的字母:
如示例所示:
如果你画0-4,你就拿a,如果你画5-9,你就拿b,10-11 =c等等
give every value a weight. E.g. a=5, b=5, c=2, .... q=1, z=2 etc
the higher the weight, the more often you want the letter to appear
to calc a random letter, add all the weights together and pick a random between 0 and the totalweight.
then select the letter which corresponds with the drawn number:
as in the example:
if you drew 0-4 you take the a, if you drew 5-9 you take b, 10-11 =c etc etc
一个简单的解决方案是使用 2 个列表。一种带有元音,一种带有辅音。
现在通过选择 N 个随机元音和 M 个随机辅音来构建新的字母表,其中 N > 。 M 和 N+M = 字母表的最大大小。
A trivial solution is to use 2 lists. One with the vowels and one with consonants.
Now construct your new alphabet by selecting N random vowels and M random consonants where N > M and N+M = max size of alphabet.
我将用伪代码编写它。假设您已经定义了字母频率:
所有元素的总和显然应该为 1。
然后您可以定义一个带有间隔的数组:
然后当您在间隔
[0; 中生成一个随机数
,你只需要遍历区间数组并找到对应的字母:n
时, 1)为了提高速度,区间数组也可以使用整数来实现。
I'll write it in pseudo-code. Let's say you have your letter frequencies defined:
Sum of all elements should obviously be 1.
Then you can define an array with intervals:
Then when you generate a random number
n
in interval[0; 1)
, you just need to run through interval array and find which letter corresponds to that:The interval array can also be implemented using integer numbers for speed.
