Shreevardhan answer works great. But if you want to use it in c++14 just make a change namespace fs = experimental::filesystem;
i.e.,
#include <string>
#include <iostream>
#include <filesystem>
using namespace std;
namespace fs = experimental::filesystem;
int main()
{
string path = "C:\\splits\\";
for (auto & p : fs::directory_iterator(path))
cout << p << endl;
int n;
cin >> n;
}
