C Program to Print names of all Files present in a Directory

dirent.h header file contains variables and functions related to directory streams.

Below is a program to print the names of all the files in a directory.

#include<stdio.h>
#include<dirent.h>

int main(void)
{
    DIR *d;
    struct dirent *dir;
    d = opendir(".");
    if (d)
    {
        while ((dir = readdir(d)) != NULL)
        {
            printf("%s\n", dir->d_name);
        }
        closedir(d);
    }
    return(0);
}

File1.txt File2.txt File3.txt File4.txt File5.txt File6.txt File7.txt

We can also take the directory name as input from the user, and can also create a simple C program to search for a particular file in a directory.
