C program to list all files in a directory recursively

Write a C program to list all files in a directory recursively.

  #include <stdio.h>
  #include <dirent.h>
  #include <string.h>
  #define MAX 256

  void listFiles(char *dname) {
        DIR *dir;
        struct dirent *ent;
        char temp[MAX];

        /* open the given directory */
        dir = opendir(dname);

        if (!dir) {
                return;
        }

        /* list all files in the given directory directory */
        printf("Files in the directory - %s:\n", dname);
        while (ent = readdir(dir)) {

                printf("%s\n", ent->d_name);
                if (strcmp(ent->d_name, ".") == 0 ||
                        strcmp(ent->d_name, "..") ==0) {
                                continue;
                }

                /* form directory name relative to current directory */
                strcpy(temp, dname);
                strcat(temp, "/");
                strcat(temp, ent->d_name);

                /* recursive call to recursively list all files */
                listFiles(temp);
        }

        /* close the opened directory */

        closedir(dir);

        return;

  }

  int main() {

        char dname[MAX];

        /* get the file name from the user */

        printf("Enter your directory name:");

        fgets(dname, MAX, stdin);

        dname[strlen(dname) - 1] = '\0';

        /* lists all files in the given directory recursively */

        listFiles(dname);

        return 0;

  }

  Output:

  Enter your directory name:mydir
  Files in the directory - mydir:
