C++ Programming By Example - Adding Test Data

This video tutorial covers the implementation of a library management system that reads book data from a CSV file. It explains how to modify the library parser to read and parse CSV data, and how to use the getline function to process input streams. The tutorial also demonstrates how to save the book library to a file, update the main application to include this functionality, and test the application to ensure it works correctly. The video concludes with an encouragement to experiment with the application by adding personal data.

What is the primary purpose of modifying the library parser in the library management system?

• To read data from a JSON file

• To write data to a database

• To display data on a web page

• To read data from a CSV file

What function is used to read a line from the input stream in the main code?

• getline

• getString

• readLine

• readStream

What does the split string helper function do?

• Splits a string by semicolons

• Splits a string by periods

• Splits a string by commas

• Splits a string by spaces

What is the purpose of creating an output file stream in the save functionality?

• To write data to a file

• To copy data from one file to another

• To read data from a file

• To delete data from a file

What is checked before writing data to the output file stream?

• If the output file is open and good

• If the output file is writable

• If the output file is empty

• If the output file is in the correct directory

In the main application, what new action is added to save the current library?

• Load new library

• Delete current library

• Export current library

• Save current library

Where is the saved CSV file located after the save operation?

• In the source directory

• In the build directory

• In the data directory

• In the temp directory

What is the expected outcome after saving the library when the data is sorted?

• The data is sorted in reverse order

• The data is sorted as expected

• The data remains unsorted

• The data is duplicated

What is encouraged at the end of the video?

• To uninstall the software

• To add more data and experiment

• To delete the application

• To ignore the application

What functionality is planned to be added in the next video?

• Update functionality

• Export functionality

• Search functionality

• Delete functionality
