What are the different types of lambda captures in C++?

In C++, lambda captures can be categorized into three types: by value, by reference, and by move.

Can you explain what 'by value' capture means?

Sure! 'By value' capture means that a copy of the variable is made and used inside the lambda. Changes to the variable inside the lambda do not affect the original variable.

And what about 'by reference' capture?

'By reference' capture allows the lambda to access the original variable directly. Any changes made inside the lambda will affect the original variable.

What does 'by move' capture do?

'By move' capture transfers ownership of the variable to the lambda, meaning the original variable can no longer be used after the capture.
