I keep getting this error when trying to compile. Can anyone help?

str.open(filename()); <-- there's an extra set of parenthesis after filename. filename is a string with the file name, not a function.

The function also doesn't know what str is - you might be getting a different compiler error for that. And the return statement isn't returning anything when the function has been defined to return something.

Sorry Im a little new to c++ in your opinion how would fix the code?

Remove the extra set of parenthesis for that error.

str.open(filename()); --> str.open(filename);

Ok i did that and i tried to compile and now Im getting these errors

Check for missing function prototypes of functions you call but don't define until after main.

You're using str in some functions where you haven't sent str as a parameter, so the function doesn't know what str is.

Function must return a value - if you define a function to return a value, but don't - you either need to return a value, or redefine the function to be void if nothing needs to be returned.

seekg is not a member - maybe you mean to use seekp? http://www.cplusplus.com/reference/ostream/ostream/seekp/

Ok i got some of them fixed but not all now Im getting these errors:

Check for missing function prototypes of functions you call but don't define until after main. You have 6 functions defined besides main, but only 4 function prototypes are listed before main.

Function must return a value - if you define a function to return a value, but don't - you either need to return a value, or redefine the function to be void if nothing needs to be returned. You're expecting something to be returned from the functions and assigned to ifile or ofile.

seekg is not a member error - maybe you mean to use seekp? http://www.cplusplus.com/reference/ostream/ostream/seekp/

Edit: Why are you making str an int? It's not an integer value.

First off I appreciate all the help and I got most off the errors to go away.I am sorry if I am not understanding but Im still getting the undeclared functions. And its saying str is undefined. and error C2228: left of '.open' must have class/struct/union type is ''unknown-type''

You've been asked once already - please use code tags to make your code more readable:

http://www.cplusplus.com/articles/z13hAqkS/
AbstractionAnon (6954)
Line 26: No forward prototype for GetInputFile.
Line 27: No forward prototype for GetOutputFile.
Line 122: No stream named str.
Line 127: stream is not returned.
Line 135: No stream named str.
Line 140: stream is not returned.

If you don't know what lines these line numbers refer to, I suggest you edit your post and apply code tags as has already been requested twice.

Is there any particular reason you're withholding the details of what those errors are?

You cannot copy a stream, hence GetInputFile(...)/GetOutputFile(...) are both invalid.

Instead pass the stream as a reference like to the other function.

Don't forget to apply the changes to the prototypes as well.
