rand() & srand()
----------------
the element of chance can be introduced into compiler application by using
the standard library function rand.
ex:
i = rand();
the function rand generates an unsigned integer between 0 and rand_max(a symbolic constant
defined in the <cstdlib>)
The valume of rand_max must be at least 32767-the maximum positive value for two_byte
integer. If rand truly produces integer at random, every number between
0 and rand_max has an equal chance(or probability) of being chosen each time. 
rand is called the range of values produced directly by rand is often different than what
is needed in a specific application. for example, a program that simulates coin tossing
might require only 0 for heads and 1 for tails; rolling a six-sided dice would require
random integers in range 1 to 6.
* to produce integers in the range 0 to 5,  we use the modulus operatior(%) in conjunction
with rand as follows:
rand % 6 
this is called scaling. the number 6 is called the scaling factor. we shift range of
numbers produced by adding 1, hence confirm that the results are in the range 1 to 6.

===================================================
due wednesday::
u work for the lotter commition, commition requests that u create a program to 
display on screen 6 different numbers.range from 1 to 59, 
the sixth number is the BONUS number..please indicate
