How to access many images from folder - visual-c++

Question

I am trying to process many picture's at a time and then make all to equal size
Mat pic = imread ("C:\\Pick");
for (int i=0;i<10;i++)
{
imshow("mainwin" , pick);
resize (pick,re_pic,size(150,100));
}
Pick is a folder which contain 10 different picture's

You can get list of images in directory and then process them.
#include <vector>
#include <stdio.h>
#include <windows.h>
#include <iostream>
#include <string>
using namespace std;
//----------------------------------------------------------------------
// Get list of files
// Usage:
// string ImagesDir=tmp+"C:\\Images\\*.jpg";
// vector<string> files=listFilesInDirectory(ImagesDir);
//----------------------------------------------------------------------
vector<string> listFilesInDirectory(string directoryName)
{
WIN32_FIND_DATA FindFileData;
HANDLE hFind = FindFirstFile(directoryName.c_str(), &FindFileData);
vector<string> listFileNames;
listFileNames.push_back(FindFileData.cFileName);
while (FindNextFile(hFind, &FindFileData))
listFileNames.push_back(FindFileData.cFileName);
return listFileNames;
}
...
// somewhere in main
string YourImagesDirectory="C:\\Pick\\";
vector<string> files=listFilesInDirectory(YourImagesDirectory+"*.jpg");
for(int i=0;i<files.size();i++)
{
Mat img=imread(YourImagesDirectory+files[i]);
imshow("mainwin" , img);
...
}
