RandomNumBetween Or random_num

[padilha007]

I need one function to Generate a random integer from a to b

Ex:
random_num(a,b);
RandomNumBetween(a,b);

Stick this in global code. Essentially it finds the maximum difference in the random numbers, and uses the normal rand. That way you get a rand within the proper range when added to the low.

Code: Select all

int
random_num (int low, int high)
{
    random = rand(high-low);
    return(low+random);
}

Code: Select all

int RandomBetween(int a,int b)
{
    int random=rand(max(a,b)-min(a,b));
    int start=min(a,b);
    return start+random;
}

With this code :
SomeNum = RandomBetween(-46, 89);
and
SomeNum = RandomBetween(89,-46);

Will be the same...
