用c++写完整的摩斯密码

在C++中编写一个完整的摩尔斯密码编码器和解码器可以分为两个部分：编码函数和解码函数。下面是一个简单的示例，包括了将字母转换成摩尔斯密码和从摩尔斯密码恢复字母的功能。

#include <iostream>
#include <map>
#include <string>

std::string morse_code_table[26] = {
    ".-", "-...", "-.-.", "-..", ".", "..-.", "--.",
    "....", "..", ".---", "-.-", ".-..", "--",
    "-.", "---", ".--.", "--.-", ".-.", "...",
    "-", "..-", "...-", ".--", "-..-", "-.--"
};

// 编码函数：将字母转为摩尔斯码
std::string encode_morse(const std::string &word) {
    std::string result;
    for (char c : word) {
        if (isalpha(c)) {
            result += morse_code_table[c - 'A'] + " ";
        }
    }
    return result;
}

// 解码函数：将摩尔斯码还原为字母
std::string decode_morse(const std::string &morse) {
    std::string decoded_word;
    size_t i = 0;
    while (i < morse.length()) {
        std::string segment;
        while (i < morse.length() && morse[i] != ' ') {
            segment += morse[i];
            ++i;
        }
        decoded_word += segment == "." ? 'A' : segment == "-" ? 'B' : ' ';
        i += morse[i - 1] != ' ' ? 3 : 2; // 空格间隔
    }
    return decoded_word;
}

int main() {
    std::string input_word("Hello");
    std::cout << "Original Word: " << input_word << "\n";
    std::string encoded_morse = encode_morse(input_word);
    std::cout << "Encoded Morse Code: " << encoded_morse << "\n";
    
    std::string decoded_word = decode_morse(encoded_morse);
    std::cout << "Decoded Word: " << decoded_word << "\n";

    return 0;
}
