A pseudo-random number generator is an algorithm for generating a sequence of numbers whose properties approximate the properties of sequences of random numbers. Computer based random number generators are almost always pseudo-random number generators. Yet, the numbers generated by pseudo-random number generators are not truly random.

There are two types of random generators: TRNGs (true random number generators) and PRNGs (pseudo-random generators). TRNGs use entropy sources like weather, atmospheric noise, thermal noise, or radioactive decay to obtain pure randomness. PRNGs are random but start to repeat after a certain number of seeds.

If you need bullet-proof random-number generation, use the Boost stuff, or C++11. For beginners, this is sufficient. Absolutely a better solution is to use Boost random number generator it was written by people who actually understand the problems associated with random numbers.

Random numbers can be generated by the Visual Basic Rnd()function, that returns a floating-point value between 0.0 and 1.0. Multiplying the random numbers will specify a wider range. For example, a multiplier of 20 will create a random number between zero and 20.
