#include <iostream>
#include <map>
#include <string>
using namespace std;

int main() {
	
	auto some_items = {1, 2, 3, 4};
	for(auto item : some_items)
		cout << item << endl;
	
	map<string,string> some_mapping = { {"ST","started"}, {"IP","in progress"}, {"DN","done"} };
	for (auto& item : some_mapping) {
		cout << item.first << "=>" << item.second << endl;
	}
	
	return 0;
}

// Note: you can get an item by value with "auto" or by reference with "auto&"
// Java will always use "by reference"
