Andrew,
Thanks for answering my question.
But, even if you seed it, the result is the same unless you seed it with a
random number. I use (time(0) + random number) as seed in my code.
I am unaware and so asking you, if
The random and the rand functions generates the same set of random numbers,
every time the code is executed. Though it would generate 2 different random
numbers if the function was called two times in a same code, if the code is
compiled and executed again, it generates the same set of random numbe
