Wierd Error

                                add(list, dataFile, listLength);
                                listLength++;
                       break;
                       default: 
                                cout << "Enter a valid command." << endl;
    }
}
}

void add(domList list[], ifstream inFile, int len)
{
     domList one;
     inFile >> one.domName >> one.ipNum;
     one.counter = 0;
     list[len] = one;
}

After compiling and running i get an error on line 37, 49, 59 and 64.

Any ideas?

Line 37:

The open function does not take a string. It takes a char*
http://cplusplus.com/reference/iostream/ifstream/open/

You're missing a } on line 56

On line 61, the object known as dataFile does not exist.

Deleted.

fixed the previous errors. now I have this even wierder error. It takes me to ios_base.h

738 C:\Dev-Cpp\include\c++\3.4.2\bits\ios_base.h `std::ios_base::ios_base(const std::ios_base&)' is private

769 C:\Dev-Cpp\include\c++\3.4.2\streambuf `std::basic_streambuf<_CharT, _Traits>::basic_streambuf(const std::basic_streambuf<_CharT, _Traits>&) [with _CharT = char, _Traits = std::char_traits<char>]' is private


And then the error on line 49 is still there.

I have also fixed the original code for all the original errors.

There is no copy constructor for streams. Pass it by non-const reference

Yay for more errors. Lines 73, 85, and 89 all say that length is undeclared. It's probably something really obvious but I just don't see it.
