Scaling -- 1
nThe method for adjusting the random number produced by a
random number generator to reside within a specified range is called scaling.
nScaling random numbers to reside within the range 0.0 to
1.0 is easily accomplished by dividing the return value of rand() by RAND_MAX.
n(rand()*1.0)/RAND_MAX
ncout << setw(10) << (rand()*1.0)/RAND_MAX;
