how to link random number generator with cpu?

// randomnumber.cpp: implementation of the randomnumber class.

randomnumber::randomnumber()
{

}

randomnumber::~randomnumber()
{

}

randomnumber::getnumber()
{
return randnumber;
}

randomnumber::generatenumber()
{
randnumber = ( rand () % 20 ) +1;
return 0;
}

i have this file which generates a random number. how to i link it into the cpu clock cycle so it is even more random? i know its supposed to go in the 'randomnumber::randomnumber()
' bit. how do i do this?

I'm not sure if I undestood your question well! but I think you might be referring to this:

Code:

---

srand(time(0));

This will randomize the generation of random number...

Remeber: you only need to include this code in your program once.

sounds about right, thanks for the input.

i may be asking lots of questions over the next 2 days as i have a uni assignment to do.

u put that bit of code in the class constructor, and when compiling the file i got stuck in a infinte loop. any ideas?

You don't even need to seed, but it is always a good idea.

Code:

---

#include <iostream>
#include <cstdlib>

int main()
{
        for (int i=0; i < 10; i++)
                std::cout << rand() % 10;
        return 0;
}

EDIT: The compiler was stuck in a loop or your program was?

it was the compiler i think. it was still compiling after about 5min, and i couldn't exit the prog as it was still building.
