random id generator

almost all programming languages provide a "generate a random number" method, that is, call this method will generate a number, we do not know in advance what the number it generates. For example, in. NET, write the following code: Random

Almost all programming languages provide the "generate a random number" method, that is, calling this method will generate a number, which we do not know beforehand. For example, write the following code in. Net: Random rand = newRandom();

The random class is a class that generates pseudo-random numbers. Its constructor has two types: new random () and new random (int32 ), the former generates a random number based on the system time at which the trigger is triggered. The latter can

when creating an examination system that can automatically generate a test, we often need to randomly generate a group of non-duplicate questions. net Framework provides a class system dedicated to generating random numbers. random. as we all know

As we all know about random numbers, computers cannot generate completely random numbers. The so-called random number generator uses a certain algorithm to perform complex operations on the pre-selected random seeds, use the generated results to
