你先寫一份出來瞧瞧
C++的關聯陣列要用到STL
不過這題也有偷吃步
提示: 'A' is a char!

怎麼把這段改成C++

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

int main() {
    std::unordered_map<char, int> dict1 = {
        {'A', 10}, {'J', 18}, {'S', 26}, {'B', 11}, {'K', 19}, {'T', 27}, 
        {'C', 12}, {'L', 20}, {'U', 28}, {'D', 13}, {'M', 21}, {'V', 29}, 
        {'E', 14}, {'N', 22}, {'W', 32}, {'F', 15}, {'O', 35}, {'X', 30}, 
        {'Y', 31}, {'G', 16}, {'H', 17}, {'Q', 24}, {'Z', 33}, {'I', 34}, 
        {'R', 25}, {'P', 23}
    };

    std::string id_text;
    while (std::cin >> id_text) {
        int total = 0;
        char first_char = toupper(id_text[0]);
        int en = dict1[first_char];
        total += en / 10 + en % 10 * 9 + id_text[id_text.size() - 1] - '0';
        id_text = id_text.substr(1, 8);
        int n = 8;
        for (char c : id_text) {
            total += (c - '0') * n;
            n--;
        }

        std::cout << (total % 10 == 0 ? "real" : "fake") << std::endl;
    }

    return 0;
}
