生成2位长的随机UUID

Question

I am Using Boost Random generator to generate Random UUID's.The Random UUID that i generate now is quite Lengthy.Instead i want to generate a UUID which is a 2 Digit like for eg:"Dz"

The Line of Code i am using now is

std::string strAK = to_string( boost::uuids::random_generator()() );

How to Modify this code and Generate a UUID which is 2 digit long.

Answer 1

Trivially,

std::string strAK = to_string( boost::uuids::random_generator()() ).substr( 0, 2 );

but as has already been commented, this isn't going to be universally unique.
