C++如何实现读取指定路径文件

#include <iostream>
#include <boost/filesystem.hpp>

using namespace std;
using namespace boost::filesystem;

int main()
{
  //指定图片读取文件夹，然后得到文件夹下的所有图片
  string pathImageFile = "e:/picture";
  path pathFile(pathImageFile);
  vector<string> imageFiles;
  for (auto f = directory_iterator(pathFile); f != directory_iterator(); f++)
  {
    if (!is_directory(f->path()))  // We eliminate directories
    {
      imageFiles.push_back(f->path().filename().string());
      cout << f->path().filename().string() << endl;
    }
    else
      continue;
  }
}
