What are the benefits of structured bindings in C++17?

Structured bindings in C++17 allow you to unpack tuple-like objects into individual variables, making code cleaner.

Can you give me an example of how to use structured bindings?

Sure! For instance, if you have a std::tuple<int, double> you can do:

std::tuple<int, double> myTuple(1, 2.5);
auto [x, y] = myTuple;

This assigns 1 to x and 2.5 to y.

Are there any downsides to using structured bindings?

One downside is that structured bindings can make code less readable if overused or used in complex expressions.

How do structured bindings compare to traditional std::tie?

Structured bindings are generally more concise and easier to read than std::tie, as they allow direct variable assignment.
