【解決方法】テキストファイルを分類しようとしています

I have 15 text files includes articles about different topics and I have another 5 text files each one includes token words about one topic politics, sports, weather, literature, history I want full (not just a sample) C++ code that read the five files that includes the token words and the 15 text files and classify each article with the appropriate topic using the tokens files then print each article with the token file which it classified to, and I want the classification by the frequency of each word in article comparing with its the frequency in token file and at the output each article with token file which it classified to

私が試したこと：

#include <iostream>
#include <fstream>
#include <string>
#include <unordered_map>
#include <vector>

using namespace std;

const int N = 20; // number of text files
const int M = 5;  // number of token files

// function to read a text file and return a vector of words
vector<string> readTextFile(string filename) {
    vector<string> words;
    string word;
    ifstream infile(filename);
    while (infile >> word) {
        words.push_back(word);
    }
    return words;
}

// function to read a token file and return a map of words to their frequencies
unordered_map<string, int> readTokenFile(string filename) {
    unordered_map<string, int> wordFreqs;
    string word;
    int freq;
    ifstream infile(filename);
    while (infile >> word >> freq) {
        wordFreqs[word] = freq;
    }
    return wordFreqs;
}

int main() {
    // read all the text files and store them in a vector
    vector<vector<string>> textFiles(N);
    for (int i = 0; i < N; i++) {
        string filename = "text" + to_string(i) + ".txt";
        textFiles[i] = readTextFile(filename);
    }

    // read all the token files and store them in a vector
    vector<unordered_map<string, int>> tokenFiles(M);
    for (int i = 0; i < M; i++) {
        string filename = "token" + to_string(i) + ".txt";
        tokenFiles[i] = readTokenFile(filename);
    }

    // classify each text file based on the token files
    for (int i = 0; i < N; i++) {
        // calculate the similarity score of the text file with each token file
        vector<double> scores(M);
        for (int j = 0; j < M; j++) {
            double score = 0;
            for (string word : textFiles[i]) {
                if (tokenFiles[j].count(word)) {
                    score += tokenFiles[j][word];
                }
            }
            scores[j] = score;
        }

        // find the token file with the highest similarity score
        int maxIdx = 0;
        for (int j = 1; j < M; j++) {
            if (scores[j] > scores[maxIdx]) {
                maxIdx = j;
            }
        }

        // print the text file and the token file it was classified to
        cout << "text" << i << ".txt" << " classified to token" << maxIdx << ".txt" << endl;
    }

    return 0;
