Fstream, ofstream, ifstream

Question

Hi class. If we use sololearn compiler to create, write or read sequential file (for example clients.dat, clients.txt) associated or assigned to ofstream object outClientfile, where do I can find the output file clients.txt or clients.dat in my computer. i could not find the output file, event I have determined the output file .txt or .dat directory by add "c:/clients.txt" in my code.
Thank you.

If you don't specify directory, the file path should be relative to either a setting in your IDE, the project's directory or the directory containing the generated exe file.

Maybe you ran into a permission issue. It is good to work on your project in a directory that doesn't have special permission requirements for reading and writing. Somewhere on the Desktop should be safe. Anywhere in Program Files or Windows directory would be bad.

Write a simple program that does nothing but write a file with a very unique name like "sdgs8dgs8ygds8gsdg8ysd_.txt" and check for any file open, permission errors...
2. Run it.
3. Search your entire file system in all drives for "sdgs8dgs8ygds8gsdg8ysd_.txt".

It would be very weird if your program ran without throwing an exception or exiting with error code yet the file wasn't written somewhere.

Here's some code:
#include <iostream>
#include <fstream>
using namespace std;

int main () {
ofstream myfile;
myfile.open ("sdgs8dgs8ygds8gsdg8ysd_.txt");
if (!myfile) {
cout << "Unable to write to file because of an error. This could be related to permissions" << endl;
}
else {
myfile << "Writing this to a file.\n";
myfile.close();
}
return 0;
}
