How can I use C++ lambda functions with STL algorithms?

What are lambda functions in C++?

Lambda functions in C++ are anonymous functions that can be defined in-line. They are often used for short snippets of code.

How do I use lambda functions with STL algorithms?

You can pass lambda functions as arguments to STL algorithms like std::sort, std::for_each, etc., to customize their behavior.

Can you give me an example of using a lambda with std::sort?

Sure! Here's an example: std::sort(vec.begin(), vec.end(), [](int a, int b) { return a > b; }); This sorts the vector in descending order.

What are some common use cases for lambda functions?

Common use cases include sorting, filtering collections, and defining custom operations in algorithms.
