ifstream problems.

Could someone please tell me the correct method of locating a file through ifstream. This it my attempt, which doesn't seem to be working.

Code:

---

  //Opens for reading the file
  ifstream b_file ( "C:\Program Files\FAH\unitinfo.txt" );
  //Reads one string from the file
  b_file>> str;
  //Should output 'this'
  cout<< str <<"\n";

Thanks,
Gareth.

Use forward slashes instead of back slashes.

Alternatively, to represent backslashes in a string, you'll need two of them together.

Code:

---

ifstream b_file ( "C:\\Program Files\\FAH\\unitinfo.txt" );

Thanks for the quick reply.

Isn't this convention a little strange, bearing in mind I copy/pasted the file address straight from a shortcut property box?

It's more proper in programming to put files into a default folder, so you don't need to type the full address when declaring the ifstream.

No.
The '\' is a operator in c++. So to tell the compiler to use a real \ and not the \ operator you have to use two \'s.

For instance if you wanted to type quotes inside of a literal constant you'd have to write:

Code:

---

cout << "Hello \"Mr President\". ";

It's also where you get operators like \n, \b, \0... etc etc.

Technically, they're called escape sequences, not operators.

Well, thank you for that correction.
