You've done the same thing both times and you expect different results :)

For ascending order, use "less" instead of "greater".

Change std::sort(a, a+size, std::greater<int>()); to std::sort(a, a+size, std::less<int>());

i have just tried that but it still sends the number out ascending?
aleonard (58)
In line 52 change greater by less. And it will work, I promise :)
btickle1 (34)
it really doesnt work, try it, any other suggestions
