有问题可以问哈，一共建3个文件，如下：

main.cpp文件

#include <iostream>
#include <sstream>
#include <fstream>
#include <string>
#include <thread>
 
#include "cmdLine.h"
#include "mutlithread.h"
 
int main(int argc, char *argv[])
{
    std::string inputPath = "/media/add7/E/testData/testThreads/";
    std::vector<std::string> fileNameList;
    for(std::size_t i = 0; i < 20; ++i)
    {
        std::stringstream ss;
        ss << i;
        std::string s;
        ss >> s;
        std::string tempPath = inputPath + "/" + s + ".txt";
        fileNameList.push_back(tempPath);
    }
 
    MutliThread myThread;
    myThread.initialization("/media/add7/E/testData/testThreads/out/");
 
 
    while(true)
    {
        if(MutliThread::writeFinish && MutliThread::showFinish)
            break;
 
        std::thread th1(MutliThread::readFile, &fileNameList, &myThread);
        std::thread th2(MutliThread::showFile);
        std::thread th3(MutliThread::writeFile, &myThread);
 
        std::cout << "join th1" << std::endl;
        th1.join();
        std::cout << "join th2" << std::endl;
        th2.join();
        std::cout << "join th3" << std::endl;
        th3.join();
    }
 
    std::cout << "threads exit !" << std::endl;
 
 
    return 1;
}
