#include <stdio.h>
#include <sys/types.h>
#include <dirent.h>
#include <limits.h>

void listFiles(const char *path)
{
    struct dirent *dn;
    DIR *dir = opendir(path);

    if (!dir) 
        return; 

    while ((dn = readdir(dir)) != NULL) {
        printf("%s\n", dn->d_name);
    }

    closedir(dir);
}

int main()
{
	char working_directory[PATH_MAX];
     
	if (getcwd(working_directory, sizeof(working_directory)) != NULL) {
		listFiles(working_directory);
	} else {
		perror("getcwd() error");
		return 1;
	}

	

    return 0;
}
