如何使用readdir統計文件數量

#<span>include <stdio.h></span> #<span>include <stdlib.h></span> #<span>include <dirent.h></span> #<span>include <sys/stat.h></span>  int main(<span>int argc, char *argv[])</span> {     if (argc != 2) {         printf("Usage: %s <directory_path>n", argv[0]);         return 1;     }      DIR *dir = opendir(argv[1]);     if (dir == NULL) {         perror("opendir");         return 1;     }      <span>struct dirent *entry;</span>     int file_count = 0;      while ((entry = readdir(dir)) != NULL) {         // 跳過當前目錄（.）和上級目錄（..）         if (strcmp(entry->d_name, ".") == 0 || strcmp(entry->d_name, "..") == 0) {             continue;         }          // 使用 stat 函數獲取文件信息         <span>struct stat file_stat;</span>         if (stat(argv[1] "/" entry->d_name, &file_stat) == 0) {             // 檢查是否為文件             if (S_ISREG(file_stat.st_mode)) {                 file_count++;             }         }     }      closedir(dir);      printf("Number of files: %dn", file_count);     return 0; } 

gcc -o count_files count_files.c 

./count_files /path/to/directory
