There exists a simple expression for getting a random value from a range:
rand() % (max - min) + min
But some prefer this kind of an expression instead even though it looks more complicated and hard to understand:
min + rand() / (RAND_MAX / (max - min + 1) + 1);
What is the advantage of using the second expression and why not to use the first one?
*The question is also about the second expression
