Random Number from 0 to X
I need a random number generator that will give me a different number each time it is executed. The purpose of this is to insert random FLOAT numbers into an array.

one addition:
The rand() function wll provide the same sequence of random integer values [0...RANDMAX] whenever your application restarts.
Use srand((unisnged int) time());
to intialize ('seed') the random number sequence.

//** a = [0...1[
double a = (double)(rand()%RAND_MAX) / RAND_MAX
will generate pseudo random floating point values between 0 and 0.999...
There are better random number generators than the standard c implentation.
Get back if you have higher demands on the randomness.
