What is C++ lambda syntax?

Can you explain what C++ lambda syntax is?

Sure! C++ lambda syntax allows you to create anonymous functions directly in your code. It's useful for short, inline functions.

How do I define a lambda function in C++?

You can define a lambda function using the syntax: [capture](parameters) { body }. For example: [&](int x) { return x * 2; }.

What are captures in lambda functions?

Captures allow you to access variables from the surrounding scope. You can capture by value or by reference using [].

Can you give me an example of using a lambda with STL algorithms?

Absolutely! You can use a lambda with std::sort like this: std::sort(vec.begin(), vec.end(), [](int a, int b) { return a < b; });.
