Answer 1

what you need is this, very simple and a standard library. Example online compiler link: http://cpp.sh/7hsxo

#include 
#include 
#include  
static std::unordered_set myset;


int main()
{
    myset.insert("blah");
    myset.insert("blah2");
    myset.insert("blah3");

    int count = 0;
    for ( auto local_it = myset.begin(); local_it!= myset.end(); ++local_it ) {
          printf("index: [%d]: %s\n", count,  (*local_it).c_str());
          count++;
    }
    printf("\n");
    for ( unsigned i = 0; i < myset.bucket_count(); ++i) {
        for ( auto local_it = myset.begin(i); local_it!= myset.end(i); ++local_it )
              printf("bucket: [%d]: %s\n", i,  (*local_it).c_str());
    }
}
