我认为，下面的代码片段可以用来列出所有的文件。

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

int main(int argc, char** argv) { 
    list_dir("myFolderName");
    return EXIT_SUCCESS;
}  

static void list_dir(const char *path) {
    struct dirent *entry;
    DIR *dir = opendir(path);
    if (dir == NULL) {
        return;
    }

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

    closedir(dir);
}

这是使用的结构(出现在direct .h中):

struct dirent {
    ino_t d_ino; /* inode number */
    off_t d_off; /* offset to the next dirent */
    unsigned short d_reclen; /* length of this record */
    unsigned char d_type; /* type of file */
    char d_name[256]; /* filename */
};

尝试x平台方法

或者只是使用特定于操作系统的文件。

Shreevardhan的设计也适用于遍历子目录:

#include <string>
#include <iostream>
#include <filesystem>

using namespace std;
namespace fs = filesystem;
int main()
{
    string path = "\\path\\to\\directory";
    // string path = "/path/to/directory";
    for (auto & p : fs::recursive_directory_iterator(path))
        cout << p.path() << endl;
}

编译:cl /EHsc /W4 /WX /std:c++17 ListFiles.cpp

我认为，下面的代码片段可以用来列出所有的文件。

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

int main(int argc, char** argv) { 
    list_dir("myFolderName");
    return EXIT_SUCCESS;
}  

static void list_dir(const char *path) {
    struct dirent *entry;
    DIR *dir = opendir(path);
    if (dir == NULL) {
        return;
    }

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

    closedir(dir);
}

这是使用的结构(出现在direct .h中):

struct dirent {
    ino_t d_ino; /* inode number */
    off_t d_off; /* offset to the next dirent */
    unsigned short d_reclen; /* length of this record */
    unsigned char d_type; /* type of file */
    char d_name[256]; /* filename */
};

这对我很管用。它用所有文件的名称(没有路径)写入一个文件。然后它读取txt文件并为你打印出来。

void DisplayFolderContent()
    {

        system("dir /n /b * > file_names.txt");
        char ch;
        std::fstream myStream("file_names.txt", std::fstream::in);
        while (myStream.get(ch))
        {
            std::cout << ch;
        }

    }

#include<iostream>
#include <dirent.h>
using namespace std;
char ROOT[]={'.'};

void listfiles(char* path){
    DIR * dirp = opendir(path);
    dirent * dp;
    while ( (dp = readdir(dirp)) !=NULL ) {
         cout << dp->d_name << " size " << dp->d_reclen<<std::endl;
    }
    (void)closedir(dirp);
}

int main(int argc, char **argv)
{
    char* path;
    if (argc>1) path=argv[1]; else path=ROOT;

    cout<<"list files in ["<<path<<"]"<<std::endl;
    listfiles(path);

    return 0;
}
