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.
