1.创建文件夹： #include <sys/types.h> #include <sys/stat.h> #include <unistd.h> #include <iostream> using namespace std; int main() { string folder_name = "new_folder"; mkdir(folder_name.c_str(), S_IRWXU | S_IRWXG | S_IROTH | S_IXOTH); //创建文件夹 return 0; } 2.复制文件： #include <stdio.h> #include <stdlib.h> int main() { FILE *fp1, *fp2; //定义两个文件指针 char ch; fp1 = fopen("file1.txt", "r"); //打开要复制的文件 fp2 = fopen("file2.txt", "w"); //打开要复制到的文件 while ((ch = fgetc(fp1)) != EOF) { fputc(ch, fp2); //复制文件 } fclose(fp1); fclose(fp2); return 0; } 3.移动文件： #include <stdio.h> #include <stdlib.h> int main() { char old_path[100] = "old_folder/file1.txt"; char new_path[100] = "new_folder/file1.txt"; int result = rename(old_path, new_path); //移动文件 if (result == 0) { printf("移动成功\n"); } else { printf("移动失败\n"); } return 0; } 4.删除文件夹： #include <unistd.h> #include <stdio.h> int main() { char folder_name[100] = "new_folder"; int result = rmdir(folder_name); //删除文件夹 if (result == 0) { printf("删除成功\n"); } else { printf("删除失败\n"); } return 0; } 5.显示文件夹中的内容： #include <dirent.h> #include <stdio.h> int main() { DIR *dir; struct dirent *ent; char folder_name[100] = "new_folder"; dir = opendir(folder_name); //打开文件夹 while ((ent = readdir(dir)) != NULL) { printf("%s\n", ent->d_name); //遍历文件夹中的文件 } closedir(dir); return 0; } 6.查看文件内容： #include <stdio.h> int main() { FILE *fp; char ch; fp = fopen("file1.txt", "r"); //打开文件 while ((ch = fgetc(fp)) != EOF) { printf("%c", ch); //输出文件内容 } fclose(fp); return 0; } 7.修改文件权限： #include <sys/stat.h> #include <stdio.h> int main() { char file_name[100] = "file1.txt"; chmod(file_name, S_IRUSR | S_IWUSR | S_IRGRP | S_IWGRP | S_IROTH); //修改文件权限 return 0; } 8.搜索文件： #include <dirent.h> #include <stdio.h> #include <string.h> int main() { DIR *dir; struct dirent *ent; char folder_name[100] = "new_folder"; char search_name[100] = "file1.txt"; dir = opendir(folder_name); //打开文件夹 while ((ent = readdir(dir)) != NULL) { if (strcmp(ent->d_name, search_name) == 0) //搜索文件 { printf("找到文件：%s\n", ent->d_name); break; } } closedir(dir); return 0; }将上述代码整合成一个完整的程序代码

以下是将上述代码整合成一个完整的程序代码：

#include <iostream>
#include <dirent.h>
#include <stdio.h>
#include <string.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>
#include <stdlib.h>

using namespace std;

// 1.创建文件夹
void create_folder()
{
    string folder_name = "new_folder";
    mkdir(folder_name.c_str(), S_IRWXU | S_IRWXG | S_IROTH | S_IXOTH); //创建文件夹
}

// 2.复制文件
void copy_file()
{
    FILE *fp1, *fp2; //定义两个文件指针
    char ch;
    fp1 = fopen("file1.txt", "r"); //打开要复制的文件
    fp2 = fopen("file2.txt", "w"); //打开要复制到的文件
    while ((ch = fgetc(fp1)) != EOF)
    {
        fputc(ch, fp2); //复制文件
    }
    fclose(fp1);
    fclose(fp2);
}

// 3.移动文件
void move_file()
{
    char old_path[100] = "old_folder/file1.txt";
    char new_path[100] = "new_folder/file1.txt";
    int result = rename(old_path, new_path); //移动文件
    if (result == 0)
    {
        printf("移动成功\n");
    }
    else
    {
        printf("移动失败\n");
    }
}

// 4.删除文件夹
void delete_folder()
{
    char folder_name[100] = "new_folder";
    int result = rmdir(folder_name); //删除文件夹
    if (result == 0)
    {
        printf("删除成功\n");
    }
    else
    {
        printf("删除失败\n");
    }
}

// 5.显示文件夹中的内容
void show_folder_content()
{
    DIR *dir;
    struct dirent *ent;
    char folder_name[100] = "new_folder";
    dir = opendir(folder_name); //打开文件夹
    while ((ent = readdir(dir)) != NULL)
    {
        printf("%s\n", ent->d_name); //遍历文件夹中的文件
    }
    closedir(dir);
}

// 6.查看文件内容
void show_file_content()
{
    FILE *fp;
    char ch;
    fp = fopen("file1.txt", "r"); //打开文件
    while ((ch = fgetc(fp)) != EOF)
    {
        printf("%c", ch); //输出文件内容
    }
    fclose(fp);
}

// 7.修改文件权限
void change_file_permission()
{
    char file_name[100] = "file1.txt";
    chmod(file_name, S_IRUSR | S_IWUSR | S_IRGRP | S_IWGRP | S_IROTH); //修改文件权限
}

// 8.搜索文件
void search_file()
{
    DIR *dir;
    struct dirent *ent;
    char folder_name[100] = "new_folder";
    char search_name[100] = "file1.txt";
    dir = opendir(folder_name); //打开文件夹
    while ((ent = readdir(dir)) != NULL)
    {
        if (strcmp(ent->d_name, search_name) == 0) //搜索文件
        {
            printf("找到文件：%s\n", ent->d_name);
            break;
        }
    }
    closedir(dir);
}

int main()
{
    create_folder();
    copy_file();
    move_file();
    delete_folder();
    show_folder_content();
    show_file_content();
    change_file_permission();
    search_file();

    return 0;
