Behavioral Design Patterns in C++ - Spreadsheet Application - II

The video tutorial discusses the implementation of an export feature that allows data to be exported in CSV and HTML formats. Initially, the export function is modified to include HTML export, but this approach violates the Open Closed Principle by requiring code modification for new formats. The tutorial highlights the need for a scalable design that accommodates new file formats without altering existing code. The next lecture will explore a solution to this problem.

What is the purpose of modifying the export function in the implementation?

• To allow data export in multiple formats

• To add a new feature for data import

• To improve the speed of data processing

• To enhance the security of data export

Which user interface element is suggested for selecting the export format?

• Slider

• Checkbox

• Text field

• Radio button

What principle is violated by modifying existing code to add new functionality?

• Interface Segregation Principle

• Liskov Substitution Principle

• Open Closed Principle

• Single Responsibility Principle

Why is the current approach of using conditional statements for export formats not scalable?

• It slows down the execution time

• It increases the file size

• It makes the code less readable and maintainable

• It requires more memory

What is the suggested solution to handle multiple export formats without modifying existing code?

• Increasing the number of conditional statements

• Reducing the number of export formats

• Implementing a new design approach

• Using a different programming language
