Answer 1

The first thing which comes to mind would be <regex>.

std::string str = "HatsyRei0123456789";

std::string name = std::regex_replace(str, std::regex("[0-9]"), "");
std::string num = std::regex_replace(str, std::regex("[a-zA-Z]"), "");

std::cout << name << " " << num;

For some reason, this works half of the time on Code Playground. The other half gives me "Compilation Error". Desktop site giving me connection issues currently, so I can't test it. However, I can confirm that it's running fine on CodeChef, OnlineGDB, Cpp.sh, etc.

Answer 2

could check it easily by regular expression and show error
`/\s/.test(name)`
