#include <iterator>
int main() {
std::map<std::string,std::string> a_map;
a_map["Geely"] = "Chinese";
a_map["Peugeot"] = "French";
a_map["Mercedes"] = "German";
a_map["Toyota"] = "Japanese";
a_map["Ford"] = "American";
a_map["Fiat"] = "Italian";
// print the first 3 items
for (auto it = std::cbegin(a_map); it != std::next(std::cbegin(a_map), 3); ++it) {
std::cout << it->first << " : " << it->second << '\n';

}
Output:
Fiat : Italian
Ford : American
Geely : Chinese
