To remove annotations from a PPT file, use the [Aspose.Slides for C++](/slides/cpp/) API, a feature-rich and easy-to-use presentation manipulation API for C++.

### Delete Annotations from PPT - C++

```cpp
auto presentation = MakeObject<Presentation>(u"example.ppt");

// Delete all comments from the presentation.
for (auto author : presentation->get_CommentAuthors())
{
    author->get_Comments()->Clear();
}

// Delete all authors.
presentation->get_CommentAuthors()->Clear();

presentation->Save(u"output.ppt", SaveFormat::Ppt);
presentation->Dispose();
```
