What are lambda expressions in C++11?

Can you explain what lambda expressions are in C++11?

Sure! Lambda expressions in C++11 are a way to define anonymous functions directly in your code.

How do I use a lambda expression to sort a vector?

You can use a lambda expression as a custom comparator in the sort function. For example: std::sort(vec.begin(), vec.end(), [](int a, int b) { return a < b; });.

What are the benefits of using lambda expressions?

They provide a concise way to write function objects, improve code readability, and can capture variables from their surrounding scope.

Can you give me an example of capturing variables in a lambda?

Certainly! You can capture variables by value or by reference. For example: [&x](int y) { return x + y; } captures x by reference.
