乘以随机数 [英] multiply random number

问题描述

假设我有一个函数rand（）可以生成一个随机的整数

在0到100之间的数字。假设rand（）非常昂贵。什么

是在0和

100之间产生10个不同随机数的最快方法？ （只调用rand（）10次......）


谢谢，


qq

Suppose I have a function rand() that can generate one integer random
number between 0 and 100. Suppose also rand() is very expensive. What
is the fastest way to generate 10 different random number between 0 and
100? (call rand() only 10 times...)

Thanks,

如果你'我不是在谈论标准函数std :: rand（），然后

你的帖子不在这里，因为它不关心C ++

语言或库。请参阅常见问题解答，了解主题：
http://www.parashift.com/c++-faq-lit...t.html#faq-5.9 。你可能想要一个处理算法的新闻组（例如，

comp.programming）或者一个处理随机数生成的新闻组。


干杯！ --M

If you''re not talking about the standard function std::rand(), then
your post is off topic here since it is not concerned with the C++
language or libraries. See the FAQ for what is on-topic:
http://www.parashift.com/c++-faq-lit...t.html#faq-5.9. You
probably want a newsgroup dealing with algorithms in general (e.g.,
comp.programming) or one dealing with random number generation.

Cheers! --M

是否存在隐藏在所有这些中的C ++语言问题？对于

一般编程问题考虑''comp.programming''。


如果你在谈论标准函数''rand''，那么它（a）没有
生成0到100个数字，它的限制是0和RAND_MAX，而（b）是

其实相当便宜。

Is there a C++ language question somewhere hiding in all this? For
general programming questions consider ''comp.programming''.

If you''re talking about the Standard function ''rand'', then it (a) doesn''t
generate 0 to 100 numbers, its limits are 0 and RAND_MAX, and (b) is in
fact quite inexpensive.

我不喜欢我认为有可能解决这个问题，并保证只有

调用rand（）10次。我错了。

I don''t think it is possible to solve that problem and guarantee to only
call rand() 10 times. I could be wrong.
