     Write a C/C++ function to write entries to a file according to void arr_process (in_array, N, start_index, stop_index, outFilename)   
  
  Solution
   ofstream fout(\"test.txt\"); //opening an output stream
    /*checking whether file could be opened or not. If file does not exist or don\'t have write permissions, file
 stream could not be opened.*/
