c++ - Having trouble processing a file from my documents in my code? -

i have searched around web , here can't seem figure out doing wrong.

i trying better file processing , c++.

for practice trying grab text file game folder , make copy of it.

here code (that can't access file).

#include <fstream>  #include <iostream> #include <string>  using namespace std;    int main()  {     //define / open files     ifstream my_input_file;     ofstream my_output_file;     string filepath = "c:/users/david laptop/documents/my games/oblivion/renderinfo.txt";     my_input_file.open(filepath);       if (my_input_file.is_open())     {         cout << "opened\n";         my_output_file.open("output_file.txt", ofstream::trunc);         char c;         my_input_file.get(c);         while (my_input_file)         {             my_output_file.put(c);             my_input_file.get(c);         }          my_input_file.close();         my_output_file.close();       }     else     {         cout << "fail\n";     }      cin.get();     return 0; } 

this seemed work both text files , .ini files when in project directory having issues getting other directiorys?

any ideas?

thanks!

your code valid , works - tried with own file instead of yours, in line

    string filepath = "c:/users/david laptop/documents/my games/oblivion/renderinfo.txt"; 

so you have not such file or it not in given path or have not such path.

correct in line , ok.

tip: find file in windows explorer, press (and keep pressing) shift) , right-click on file. context menu choose copy path , paste code. carefull - have change every backslash (\) forward slash (/) (as in code) or use double backslashes (\\) instead of single one.
