[plz help]confusion about comparison between two strings to me

This is a discussion on [plz help]confusion about comparison between two strings to me within the C++ Programming forums, part of the General Programming Boards category; My guess is that there is a stray '\r' in there which might be why it is different on windows ...

    My guess is that there is a stray '\r' in there which might be why it is different on windows and linux. A carriage return will cause the cursor to go to the start of the line, which would be why the "<--" is at the start of the line instead of after the string.

    How are you reading the data into the Database array? That's likely where the problem (or at least the solution) is.

    You are probably printing back-spaces or some other "move the cursor" characters that happen to be the rubbish in some un-initialized variable - that would be my theory at least.

    When you read a file in text mode, the carriage returns and linefeeds are automatically converted to a single character: '\n'. In binary mode that doesn't happen, though, so you may get different behavior depending on your platform.

    Did you edit the file that has the records by hand (i.e. in an editor outside of your code)?

    the reading is:
    Code:
    while(!InData.eof())
                {
    		InData.getline(Database[NumBooks].CallNumber,MaxCallNumber+1,'\n');
            	InData.getline(Database[NumBooks].Title,MaxTitle,'\n');
                    InData.getline(Database[NumBooks].Author,MaxAuthor,'\n');	
                    InData.getline(Database[NumBooks].BookStatus,MaxBookStatus,'\n');
    
                    if (Database[NumBooks].BookStatus[0]=='2')
            		{
                        InData.getline(Database[NumBooks].DueDate,MaxDueDate);
                        for (int i = 0; i < MaxDueDate; i++)
                        {
                            if (Database[NumBooks].DueDate[i] == ' ')
                                Database[NumBooks].DueDate[i] = '/';
                        }
                        
                        InData.getline(Database[NumBooks].BorrowersName,MaxBorrowersName,'\n');
                    }
                    else
                    {
                        strcpy(Database[NumBooks].DueDate,"N/A");
                        strcpy(Database[NumBooks].BorrowersName,"N/A"); 
                    }
                    NumBooks++;
                }
                InData.close();
                cout << "Txt file was successfully loaded!" << endl;
    i think the reading has problem... but i dunno how to read... was i right to write like that?
