What is lambda capturing in C++11?

Can you explain what lambda capturing means in C++11?

Sure! Lambda capturing in C++11 allows you to capture variables from the surrounding scope into a lambda function.

How do I capture variables by value and by reference?

You can capture by value using [=] and by reference using [&]. For example, [x, &y] captures x by value and y by reference.

What happens if I modify a captured variable inside the lambda?

If you capture by value, the lambda works with a copy, so modifications won't affect the original variable. If captured by reference, changes will reflect in the original variable.

Can I capture all variables in the scope?

Yes, you can use [&] to capture all variables by reference or [=] to capture all by value.
