In a statistics book there is an algorithm of generating pseudo-random numbers with uniform distribution [0,1]. It says:

I. Enter an initial variable X positive integer.

II. Multiply X by variable "a", which should be at least 5 digits long.

III. Divide a*X by value p (positive integer).

IV. Take the fraction part of the division as a first pseudo-random number.

V. Make the number from step IV into integer by a necessary multiplication and use it in step II.

VI. Step II-V are repeated to generate more pseudo-random numbers.

Here is what I have:

```
#include <cstdlib>
#include <iostream>
using namespace std;
int main(int argc, char *argv[])
{
int x,a,p;
cout << "Enter initial positive integer number: ";
cin >> x;
cout << "Enter positive integer a: ";
cin >> a;
cout << "Enter positive integer p: ";
cin >> p;
for(int i=1; i<=12; i++)
{
x=(a*x % p);
cout << x << endl;
}
system("PAUSE");
return EXIT_SUCCESS;
}
```

How do I realize steps 4 and 5? I need to obtain random numbers between 0 and 1 and **later use them in some other calculations**. Please, help.
