Hello,

Im writing a banking system program for one of my assignments using classes, i've got the some basic stuff done but I can't for the life of me work out how to read data out of a file i've previously created and display it on screen. (I've cut the code down so it's easier to read on here)

The part im stuck on is the Current::DisplayDetails class, doing it the way I have at the moment throws an error:

error C2664: 'class std::basic_istream<char,struct std::char_traits<char> > &__thiscall std::basic_istream<char,struct std::char_traits<char> >::getline(char *,int)' : cannot conv
ert parameter 1 from 'class std::basic_fstream<char,struct std::char_traits<char> >' to 'char *'

Can anyone help? :)

fstream checkFile("current.dat", ios::in | ios::binary | ios::beg);
cin.getline(checkFile, sCusName);

getline is looking for a char pointer instead of basic_fstream

You don't need the cin because you are not taking input from the keyboard. Use checkFile.getline(sCusName,30); If you have multiple customers in a file you're going to need a loop to access the one you need.
