C++ Program To Display The List Of Current Directory/Folder Using File

In this tutorial, we will be learning how to display the list of current directory or folder using file.

C++ Program For Displaying The List of Current Directory/Folder Using File(First Method)

#include<iostream>
#include<dirent.h>
using namespace std;
int main()
{
    struct dirent *d;
    DIR *dr;
    dr = opendir(".");
    if(dr!=NULL)
    {
        cout<<"List of Files & Folders:-\n";
        for(d=readdir(dr); d!=NULL; d=readdir(dr))
        {
            cout<<d->d_name<<endl;
        }
        closedir(dr);
    }
    else
        cout<<"\nError Occurred!";
    cout<<endl;
    return 0;
}

C++ Program For Displaying The List of Current Directory/Folder Using File(Second Method)

This program does the same job as of previous program, but using while loop, instead of for loop.

#include<iostream>
#include<dirent.h>
using namespace std;
int main()
{
    struct dirent *d;
    DIR *dr;
    dr = opendir(".");
    if(dr!=NULL)
    {
        cout<<"List of Files and Folders:-\n";
        while((d=readdir(dr))!=NULL)
            cout<<d->d_name<<endl;
        closedir(dr);
    }
    else
        cout<<"\nError Occurred!";
    cout<<endl;
    return 0;
}

Conclusion

Here, in this tutorial, we have implemented the C++ program for displaying the list of current directory/folder using file.
