Description: 均匀分布伪随机数发生器
伪随机数在计算机软件设计中有很广泛的用途。本文介绍了基于数学方法的利用计算机产生伪随机数的一种方法，即线性同余法，任何伪随机数的产生都是运用递推的原理来生成的。以及在Visual C++环境中产生伪随机数的两个重要函数，rand和srand函数，正确地使用这两个函数是产生性能良好的伪随机数的关键

-Uniformly distributed pseudo-random number generator, pseudo-random number in the computer software design in a very wide range of functions. This paper introduces the mathematical methods based on the use of computer generated pseudo-random number in a way that the linear congruence method, any pseudo-random number generated is to use the principle of recursive generated. As well as in Visual C++ Environment pseudo-random number generated two important functions, rand and srand functions, proper use of these two functions is the good performance of the pseudo-random number key

Description: 2、 编写一个产生1000个1到10范围内的随机数的程序。不要保存或打印数字，仅打印每个数被产生了多少次。让程序对10个不同的种子值进行计算。数字出现的次数相同吗？可以使用自定义的随机函数或ANSI C中的函数rand()和srand()。这是一个测试特定随机数发生器的随机性的方法。-1000 arising from the preparation of a 1-10 range of the random number procedure. Do not save or print the number, only a few were produced for each print the number of times. Procedures to allow the seeds of 10 different calculated values. The same number of figures it? Can use custom or random function in the ANSI C function rand () and srand (). This is a test-specific random number generator of the stochastic approach.
