Random Numbers - DIE Example - C++ / GNU

A program that illustrates the Random Number Generation, with Rolling Dice.
It will run only on Unix environment.





Code:
/*
Header: iostream
Reason: Input/Output stream
Header: stdlib
Reason: For functions rand and srand
Header: time.h
Reason: For function time, and for data type time_t
*/
#include <iostream>
#include <cstdlib>
#include <time.h>
/*
These constants define our upper
and our lower bounds. The random numbers
will always be between 1 and 6, inclusive.
*/
const int LOW = 1;
const int HIGH = 6;

Variables to hold random values
for the first and the second die on
each roll.
*/

/*
Declare variable to hold seconds on clock.
*/

/*
Get value from system clock and
place in seconds variable.
*/

/*
Convert seconds to a unsigned
integer.
*/

/*
Get first and second random numbers.
*/

/*
Output first roll results.

/*
Get two new random values.
*/

Output second roll results.
*/
