Are there any better methods to do permutation of string?

Question

void permute(string elems, int mid, int end)
{
    static int count;
    if (mid == end) {
        cout << ++count << \" : \" << elems << end

Here's one I just rustled up!!

void permute(const char* str, int level=0, bool print=true) {

    if (print) std::cout << str << std::endl;

    char temp[30];
    for (int i = level; i
