If you replace cin >> s: with getline(cin, s); it also supports full names.

cin extraction always considers spaces (whitespaces, tabs, new-line...) as terminating the value being extracted, and thus extracting a string means to always extract a single word, not a phrase or an entire sentence. To get an entire line from cin, there exists a function, called getline, that takes the stream (cin) as first argument, and the string variable as second.
