c++ - 如何在一个 vector 中分配多个不同类型的变量或区分其类型

Question

我在 worldGiving.txt 和 OrganDonor.txt 中有两个不同的数据集，如下所示

下面是我的代码。

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

using namespace std;

string line;
vector<vector<string>> extractingData;
vector<vector<string>> extractingData2;

string pathExtract;
string pathStorage;
string pathMerged;

fstream extractingFile;
fstream extractingFile2;

void mergeData(vector<vector<string>> extractingData, vector<vector<string>> extractingData2, string pathStorage);

vector<vector<string>> ReadData(fstream& extractingFile, vector<vector<string>> extractingData, string pathExtract)
{
    extractingFile.open(pathExtract);

    int i = 0;
    int index;
    if (extractingFile.is_open())
    {
        while (getline(extractingFile, line))
        {
            istringstream iss(line);
            extractingData.resize(i + 1);
            int j = 0;
            while (!iss.eof()){
                extractingData[i].resize(j+1);
                iss >> extractingData[i][j];
                j++;
            }
            i++;
        }
        return extractingData;
    }
}


int main() {
    pathExtract = "worldGiving.txt";
    pathStorage = "OrganDonors.txt";
    pathMerged = "merged.txt";
    extractingData=ReadData(extractingFile, extractingData, pathStorage);
    extractingData2=ReadData(extractingFile2, extractingData2, pathExtract);
    mergeData(extractingData, extractingData2, pathMerged);

}


void mergeData(vector<vector<string>> extractingData, vector<vector<string>> extractingData2, string pathStorage){

    int i = 0;
    int j = 0;
    while (i<extractingData2.size() && i<extractingData.size())
    {
        cout << extractingData[i][0];
        while (extractingData[i][0] != extractingData2[j][0] && j != extractingData2.size()-1)
        {
            j++;
        }
        if (extractingData[i][0] == extractingData2[j][0])
        {
            for (std::vector<string>::iterator it = extractingData2[j].begin()+1; it != extractingData2[j].end(); ++it)
            {
                /*auto back = std::move(extractingData2[j].back);
                extractingData[i].push_back(std::move(back));*/
                auto back = *it;
                extractingData[i].push_back(back);
            }

        }   
        i++;
        j = 0;
    }


        i = 0;
        ofstream outFile(pathStorage);
        while (i<extractingData2.size() && i<extractingData.size())
        {
            for (std::vector<string>::iterator it = extractingData[i].begin(); it != extractingData[i].end(); ++it) {
                outFile << *it <<' ';
            }
            outFile << endl;
            i++;
        }   
    }

但我遇到了一个问题，多个名为“New Zealand”和“United States”等国家/地区的术语分别分配在多个 block 中，例如“New”、“Zealand”。 所以我不能适本地比较两个文本文件。所以我想如果我能在将它分配给 Vector 时区分它的类型是数字还是非数字，我就可以解决这个问题。 我该怎么办？

如果您不能更改格式以更清楚地划分国家/地区名称，您可以计算找到的项目数量并从头到尾分配它们。找到您的值(value)观后剩下的应该加入名称。
