    calculating probability::options?

    i've been calculating probability for a program of mine
    i've been using srand, rand()%2 for say a 50-50
    i'd use a if to see if it was between 0 and 1 for one outcome and greater than 1 for the other. It works, but, is there a more accurate or better way to do this?

    In all honesty, there may be more of a dearth than a plethora of worms concerning your question here.

    I ran rather quickly, truth be told, with the rand() thing - which has been done to death - without engaging my brain to incorporate the remainder of your question. My fault.

    After some not too serious looking on my own, I basically came up with squat, too.

    Sorry Waldo2k2.

    well i did find a very obscure way of doing this today using the left shift operator on a series of bits...all in all it comes out with either a 1 or a 0 in the value of a variable. It works for me.
