What are some advanced functions in C++ that I should know about?

Some advanced functions in C++ include lambda expressions, function templates, and std::function. Would you like to explore any of these?

Can you explain lambda expressions?

Sure! Lambda expressions are a way to create anonymous functions in C++. They allow you to define a function inline without needing to name it. Here's a simple example: [](int x) { return x * x; }.

How do function templates work?

Function templates allow you to create a function that can operate on different data types without rewriting the code. You define a template using the 'template' keyword.

Can you give me an example of a function template?

Absolutely! Here's a simple example:

template <typename T>
T add(T a, T b) {
    return a + b;
}

This function can add integers, floats, or any other type that supports the '+' operator.
