Answer 1

#include <iostream>
#include <unordered_map>
#include <string>

using std::string;
using std::cout;
using std::endl;

int main() 
{
	std::unordered_map<string, int> workers({{ "Liam ", 45}, { "Logan", 37}, { "Ethan", 51}});

	std::unordered_map<std::string, int> w2(workers.begin(), workers.end());

	for (std::pair<std::string, int> element : w2)
		cout << element.first << " - " << element.second << endl;

	return 0;
}

/*
