Hi, I can sort a int* array using stl, plain and simple like
std::sort(myarray, myarray + size);
Is there any equal simple way to randomize it?
thanks

+1, also, Boost.Random has some good random number generators to go with it, if you want something higher-quality than the RNG used by default. :-P

Who says it doesn't use a high-quality RNG already? :P At least with your own RNG you can control it, which is immensely useful for things like unit tests.

A:
If you want to generate new random content instead of shuffling the elements that are already there:
std::generate_n(myarray, size, &std::rand);

+1: I don't think this is what the questioner meant, but well done for noticing the ambiguity in "randomize" :-)
