Fundamentals of Object-Oriented Programming - C++ - Classes - File I/O Program

The video tutorial explains how to implement file input and output operations within a class in C++. It covers creating a Patient class with methods for reading and writing data to a file, handling file streams, and debugging the program. The tutorial demonstrates using member functions to manage file operations and includes a practical example of storing and retrieving patient records.

What is the purpose of including file input and output operations as member functions of a class?

• To reduce the number of classes

• To enhance the natural flow of operations

• To avoid using streams

• To make the code more complex

What are the protected properties defined in the Patient class?

• Address and phone number

• Name and address

• Name and age

• Age and gender

Which method is used to prompt the user to enter patient information?

• writeFile

• readFile

• getData

• showData

What is the purpose of the readFile method in the Patient class?

• To delete patient records

• To read data from a file

• To write data to a file

• To display patient data

Which library is used to convert the file to a binary stream?

• iostream

• fstream

• iOS

• string

What does the NUM records method return?

• The size of the file

• The number of patient records

• The total number of files

• The number of errors in the file

How does the program determine when to stop accepting new patient records?

• When the user enters 'N'

• When the file is full

• When the user enters 'Y'

• When the program crashes

What issue was fixed by changing the input method for the patient's name?

• The program was crashing

• The name was not being saved

• The program was only accepting the age

• The file was not being created

What change was made to fix the issue with entering patient names?

• Using getline instead of cin

• Using cin instead of getline

• Using a different file format

• Changing the data type of age

What does the final program output after entering patient records?

• The number of patient records and their details

• The total number of errors

• The size of the file

• The list of patient names only
