What are lambda expressions in C++ and how do they capture types?

What are lambda expressions in C++?

Lambda expressions in C++ are a way to define anonymous functions directly in your code, allowing for more concise and flexible function definitions.

How do lambda expressions capture variables?

Lambda expressions can capture variables by value or by reference. You specify this in the capture clause, which is the part before the parameter list.

Can you give me an example of capturing by value?

Sure! Here's an example: int x = 10; auto lambda = [x]() { return x + 1; }; This captures x by value.

What about capturing by reference?

For capturing by reference, you would use & in the capture clause. For example: int x = 10; auto lambda = [&x]() { return x + 1; }; This allows the lambda to modify x.
