C++ map key exists

#include <iostream>
#include <map>

using std::cout; using std::cin;

                                         {"l", "Lua",}};

    for (const auto & [key, value] : lang_map) {
        cout << key << " : " << value << endl;
    }

    cout << "Enter the key to search for: ";
    cin >> key_to_find;

    if (lang_map.find(key_to_find) != lang_map.end()) {
        cout << "Key Exists!" << endl;
    }
