问题描述
我试图预测使用msvcrt的rand（）函数生成三个骰子的脸的程序的输出。我相信代码是这样的：
dice [0] = rand（）％6 + 1; dice [1] = rand（）％6 + 1; dice [2] = rand（）％6 + 1; ，我想知道我是否可以使用线性同余发生器的预测程序来预测序列中的下一个数字。
I am trying to predict the output of a program that uses msvcrt's rand() function for generating the face of three dice. I believe the code is something like:dice[0] = rand() % 6 + 1; dice[1] = rand() % 6 + 1; dice[2] = rand() % 6 + 1;, and I was wondering if I could use a prediction program for linear congruential generators to predict the next numbers in the sequence.
推荐答案
查看自己： C：\Program Files \Microsoft Visual Studio 8 \VC \crt\ src\rand.c
（或使用％VCINSTALLDIR％\crt\src\rand。
(Or use %VCINSTALLDIR%\crt\src\rand.c if you're running from a VC command prompt.)
（假设您至少拥有 标准版本 > of VC。这是两行，我会发布，但不知道许可证是否允许。）
(Assuming you have at least the standard version of VC. It's two lines. I'd post it, but not sure whether the license allows it.)
