我有一个变量 f 声明为 vector::iterator 并且我让它指向一个 c_str() 因为我试图从一个目录中读取文件。代码一开始是编译的,但我的函数都没有被调用。显示我可以编写我的类和函数以允许我传递它并在另一个函数中使用它:这是 int main() 中代码的一部分。
int main() {
vector<string> files;
if (d) {
//we successfully opened the directory
//while there's still something we haven't looked at
while ((dir = readdir(d)) != NULL) {
//get the name of that thing
string filename = dir->d_name;
//filter out what we don't want
if (filename == "." || //filter out current dir
filename == ".." || //filter out parent dir
filename.find(".csv") == string::npos) //here is where you set up the match
continue;
//and add what we do want to our files data structure
files.push_back(basepath + "/" + filename);
}
}
map<string, int> foo;
double fail = 0;
for (vector<string>::iterator f = files.begin(); f != files.end(); ++f) {
Extract_Organize process;
cout << "What";
process.transform();
process.create_file();
cout << "Finished!\n";
}
return 0;
}
class Extract_Organize {
public:
Extract_Organize;
void transform();
void create_file();
string double_integrate(int, int);
};
