用c++代码做一个动物识别专家系统，可以区分食肉哺乳动物，并且根据特征还可以进一步细分

好的，以下是一个可以区分食肉哺乳动物并根据特征进一步细分的动物识别专家系统的C++代码示例：

#include <iostream>
#include <string>
using namespace std;

int main() {
    string answer1, answer2, answer3, answer4;
    cout << "Welcome to the Animal Identification Expert System!" << endl;
    cout << "Please answer the following questions with 'yes' or 'no'." << endl;
    cout << "Does the animal have fur?" << endl;
    cin >> answer1;
    if (answer1 == "yes") {
        cout << "Is the animal a carnivore?" << endl;
        cin >> answer2;
        if (answer2 == "yes") {
            cout << "Is the animal a member of the cat family?" << endl;
            cin >> answer3;
            if (answer3 == "yes") {
                cout << "The animal is a cat." << endl;
            }
            else {
                cout << "The animal is a dog." << endl;
            }
        }
        else {
            cout << "Is the animal a herbivore?" << endl;
            cin >> answer3;
            if (answer3 == "yes") {
                cout << "The animal is a rabbit." << endl;
            }
            else {
                cout << "The animal is an omnivore." << endl;
            }
        }
    }
    else {
        cout << "Does the animal have feathers?" << endl;
        cin >> answer2;
        if (answer2 == "yes") {
            cout << "The animal is a bird." << endl;
        }
        else {
            cout << "Is the animal a carnivore?" << endl;
            cin >> answer3;
            if (answer3 == "yes") {
                cout << "Is the animal a member of the bear family?" << endl;
                cin >> answer4;
                if (answer4 == "yes") {
                    cout << "The animal is a bear." << endl;
                }
                else {
                    cout << "The animal is a wolf." << endl;
                }
            }
            else {
                cout << "The animal is a herbivore." << endl;
            }
        }
    }
    return 0;
}

这个程序基于一系列问题来识别动物种类。首先询问动物是否有毛发，然后询问它是否是食肉动物。如果是食肉动物，则进一步询问它是否属于猫科或犬科动物，如果不是，则属于杂食动物。如果动物没有毛发，则询问是否有羽毛。如果没有羽毛，则进一步询问它是否是食肉动物，如果是，则进一步判断是否属于熊科动物，如果不是，则属于狼科动物。如果是草食动物，则直接输出其种类。
