C++ printing out file names in ascending order
c++, file, sorting
Solution
Put the file names into a vector as you read them.
When you've read all of them, use `std::sort` to sort the array.
Then process the sorted file names as you see fit.
Problem
I am using the following code to iterate through files in the directory. All the files in this directory are numbered, each with a unique number. The code below successfully prints out all the files in the directory however not in ascending order. It comes out completely random and one file is duplicated. I can't find another way of printing out the files or printing them in ascending order. I really need to print them in ascending order and then later open them in ascending order. Any help is appreciated. `DIR *dpdf; struct dirent *epdf;` ``` dpdf = opendir("/data/files"); if (dpdf != NULL){ while (epdf = readdir(dpdf)){ printf("%s\n",epdf->d_name); // std::out << epdf->d_name << std::endl; } } ```
