Let's say I have
double a[N][M] = { .......};
How to transform a into a 2D vector
vector< vector > v
?
I know for 1d case, you can do the following:
int myints[] = {16,2,77,29};
vector fifth (myints, myints + sizeof(myints) / sizeof(int) );
But what about 2d?

Such as we use SMTP for email and HTTP for WWW service, what protocol is
used to encode and decode the DNS package above UDP? Is the DNS the
protocol name?
