本文介绍了如何写入txt文件。的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
(outputFile<< files [i]<<<< fileInfo.st_size<<'\ n';;)不会写入files.txt。
我的尝试:
The (outputFile << files[i]<<" " << fileInfo.st_size << '\n';) wont write to "files.txt".
What I have tried:
#include <iostream>
#include <ctime>
#include <sys/types.h>
#include <sys/stat.h>
#include <cerrno>
#include <cstring>
#include <sys/types.h>
#include <dirent.h>
#include <errno.h>
#include <vector>
#include <string>
#include <fstream>
using namespace std;
/*function... might want it in some class?*/
int getdir (string dir, vector<string> &files)
{
DIR *dp;
struct dirent *dirp;
if((dp = opendir(dir.c_str())) == NULL) {
cout << "Error(" << errno << ") opening " << dir << endl;
return errno;
}
while ((dirp = readdir(dp)) != NULL) {
files.push_back(string(dirp->d_name));
}
closedir(dp);
return 0;
}
int main(int argc, char** argv )
{
std::string dir = string(".");
vector<string> files = vector<string>();
getdir(dir,files);
std::ofstream outputFile;
outputFile.open("Files.txt");//<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
for (unsigned int i = 2;i < files.size();i++) {
struct stat fileInfo;
if (stat(files[i].c_str(), &fileInfo) != 0) {
std::cerr << "Error: " << strerror(errno) << '\n';
}
if ((fileInfo.st_mode & S_IFMT) == S_IFDIR)
outputFile << files[i]<<" " << fileInfo.st_size << '\n';//<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
cout << files[i]<<" " << fileInfo.st_size << '\n';
}
cin.get();
}
推荐答案
if ((fileInfo.st_mode & S_IFMT) == S_IFDIR)
你真的需要这个条件吗?由于这种情况,只有目录名称将写入文件。
Do you really need this condition? Due to this condition, only directories names will be written to the file.
