用C++写一个聊天机器人程序

好的，下面是一个简单的C++聊天机器人程序：

#include <iostream>
#include <string>
#include <vector>
#include <algorithm>

using namespace std;

string toLowerCase(string str) {
    transform(str.begin(), str.end(), str.begin(), ::tolower);
    return str;
}

int main() {
    vector<string> greetings = {"hello", "hi", "hey", "what's up", "yo"};
    vector<string> farewells = {"bye", "goodbye", "see you later", "see ya"};
    vector<string> compliments = {"great", "fantastic", "excellent", "awesome", "good job"};
    vector<string> insults = {"stupid", "idiot", "dumb", "moron", "fool"};

    cout << "Hello! I am a chatbot. What is your name?" << endl;

    string name;
    getline(cin, name);

    cout << "Nice to meet you, " << name << "! Ask me anything." << endl;

    while (true) {
        string input;
        getline(cin, input);

        input = toLowerCase(input);

        bool foundResponse = false;

        for (string greeting : greetings) {
            if (input.find(greeting) != string::npos) {
                foundResponse = true;
                cout << greeting << " to you too!" << endl;
                break;
            }
        }

        for (string farewell : farewells) {
            if (input.find(farewell) != string::npos) {
                foundResponse = true;
                cout << farewell << "! Have a nice day." << endl;
                return 0;
            }
        }

        for (string compliment : compliments) {
            if (input.find(compliment) != string::npos) {
                foundResponse = true;
                cout << "Thank you! I try my best." << endl;
                break;
            }
        }

        for (string insult : insults) {
            if (input.find(insult) != string::npos) {
                foundResponse = true;
                cout << "That's not very nice." << endl;
                break;
            }
        }

        if (!foundResponse) {
            cout << "I'm sorry, I don't understand. Could you please rephrase?" << endl;
        }
    }

    return 0;
}

这个程序有一些简单的规则来处理输入和相应输出。它从终端读取输入并将其转换为小写字母，然后检查输入是否包含特定的问候、告别、恭维或侮辱。如果找到了相应的输入，程序将输出相应的响应。如果程序无法理解输入，它将输出一个通用的错误消息。
