Complete Modern C++ - std::variant - I

The video tutorial introduces the concept of a variant as a type-safe replacement for the Union type. It explains how variants are initialized and accessed, highlighting the differences from Union, such as automatic destruction of members. The tutorial covers how to handle exceptions when accessing inactive or non-existent members using the get function, and introduces the get_if function for safer access. The video concludes with a brief overview of what will be covered in the next lecture, focusing on modifying active elements and initializing inactive ones.

What exceptions can be thrown when accessing members of a variant?

How does the get function differ from the get_if function in terms of exception handling?

What should you consider when specifying the type or index of an active element in a variant?
