[C++知识库]c++ 遍历文件夹下的所有文件

遍历文件夹下的所有文件：代码实现

#include <iostream>
#include <dirent.h>
#include <vector>
#include <cstring>

void GetFileNames(std::string path, std::vector<std::string> &filenames)
{
    DIR *pDir;
    struct dirent* ptr;
    if(!(pDir = opendir(path.c_str()))){
        std::cout<<"Folder doesn't Exist!"<<std::endl;
        return;
    }
    while((ptr = readdir(pDir))!=0) {
        if (strcmp(ptr->d_name, ".") != 0 && strcmp(ptr->d_name, "..") != 0){
            filenames.push_back(path + "/" + ptr->d_name);
        }
    }
    closedir(pDir);
}


int main() {
    std::vector<std::string> file_name;
    std::string path = "/home/mi/桌面/res_imgs";
    GetFileNames(path, file_name);

    for(int i = 0; i <file_name.size(); i++)
    {
        std::cout<<file_name[i]<<std::endl;
    }
    return 0;
}
