在C++ 中,随机数生成器(Random Number Generator, RNG)可以分为两大类:伪随机数生成器:它们使用确定性算法生成看似随机的数列。这些数列在理论上是可预测的,但通常对于大多数应用来说足够随机。 真随机数生成器:它们基于物理过程(如热噪声、放射性衰变等)生成随机数,但 C++ 标准库不直接提供这类生成器。

Random的随机性安全性并不高,而RandomNumberGenerator是一种密码强度的随机数生成器。 代码语言:javascript 复制 varrand=System.Security.Cryptography.RandomNumberGenerator.Create();byte[]bytes=newbyte[32];rand.GetBytes(bytes); 字节数组的长度决定了生成的随机字节数。之后用base64转成字符串就可以了。

默认随机数生成器是 std::default_random_engine 类型别名定义的随机无符号整数的通用源。这个别名表示实现是被定义的,选择的模板类型参数需要能够为用户提供他们满意的序列。下面是一种生成 default_random_engine 类型的迭代器的简单方式: std::default_random_engine rngl; // Create random number generator with ...

I don't think a "random number generator" is actually what you're looking for. Simply create another map and pre-populate it with random values. If your current heightmap is W x H, the simplest solution would be to create a W x H 2D array and just fill each element with a random...
