What are advanced lambda expressions in C++?

Advanced lambda expressions in C++ allow you to create anonymous functions with complex behaviors, including capturing variables by value or reference.

Can you explain how to capture variables in a lambda expression?

Sure! You can capture variables in a lambda by specifying them in the capture clause, like this: [&x, y] captures x by reference and y by value.

What are some use cases for lambda expressions?

Lambda expressions are great for callbacks, sorting algorithms, and any situation where you need a short, inline function.

Are there any performance considerations when using lambdas?

Yes, capturing by reference can lead to dangling references if the captured variables go out of scope. Always ensure the lifetime of captured variables.
