What are lambda expressions in C++11?

Lambda expressions in C++11 are a way to define anonymous functions directly in your code, allowing for more concise and flexible function definitions.

Can you give me an example of a lambda expression?

Sure! Here's a simple example: auto add = [](int a, int b) { return a + b; }; This defines a lambda that adds two integers.

How do I use this lambda in a function?

You can pass the lambda as an argument to functions that accept callable types, like std::function or algorithms from the STL.

What are the benefits of using lambda expressions?

They provide cleaner code, reduce the need for separate function definitions, and can capture variables from their surrounding scope.
