Pseudo Random Number Generator

------------------------------

This example uses a

`Linear Congruential Generator (LCG) `_ to generate Pseudo Random Numbers.

.. code-block:: c

    /*globals*/

    unsigned long int seed;

    void srand(unsigned long int s){

        seed = s;

    }

    unsigned long rand(){

        const unsigned long a = 1103515245ul;

        const unsigned long c = 12345ul;

        seed = (a*seed+c);

        return seed;

    }

    void main(){

        unsigned i;

        for (i=0; i<4096; i++){

            file_write(rand(), "x");

            file_write(rand(), "y");

            file_write(rand(), "z");

        }

    }
