Array problem

[Guest]

Can anybody tell me how I can put the elements of an array in a random
order? Like: 1,2,3,4,5 -> 3,2,5,1,4

There's a std routine to shuffle vectors etc
random_shuffle(v.begin(), v.end());

#include <algorithm>

int main()
{
int a[5] = {1, 2, 3, 4, 5};
std::random_shuffle(a, a + 5);
}
