// Ensure you have the necessary using directives for any external libraries or namespaces.
using IronPPT;

// Instantiate a new PresentationDocument object.
var document = new PresentationDocument();

// Add three slides to the presentation.
// The AddSlide method creates a new slide and adds it to the list of slides in the document.
document.AddSlide();  // Add first slide
document.AddSlide();  // Add second slide
document.AddSlide();  // Add third slide

// Save the presentation to a file named "addSlides.pptx".
// The Save method takes a file path as an argument and writes the current state of the presentation to this file.

// is a part of IronPPT that helps create or modify PowerPoint presentations

// and then insert it back at the desired position.
