What is the real code behind random function?

Question

when we use or call random function we get a value btw 0 and 1 (in java) ..... but what is the original code written within that function which generates it... I googled and got something named PRNG from wiki which is complex to understand.... can anyone help me to explain what is written inside random function and how does it generate a number when we call it...??

Answer 1

A simple sample.

Answer 2

PRNG is an algorithm that uses a seed number(example: current millisecond) to generate a seemingly random number and uses that new number as seed to generate the next one.

Check out this code and play with the values and see the result

Answer 3

thnx it helped a lot 😊👌

Answer 4

int i;
cout<<i;
or
char a;
cout<<a;
you will get random numbers and symbols...

Answer 5

Most pseudo random number generators use the group structure of elliptic curves to generate random looking numbers. The seeds that they use often come from a so called entropy pool, which on Linux is provided by the kernel and is created from different timings of things happening on the system, like different interrupt and so on

Answer 6

cool solution.... Thnx

Answer 7

The random class is an algorithm and is a pseudo generator.Its part of the MATH/Generator class.
