What are some modern features of C++?

C++ has introduced several modern features, such as smart pointers, lambda expressions, and the range-based for loop. Would you like to know more about any specific feature?

Can you explain smart pointers?

Smart pointers in C++ are objects that manage the lifetime of dynamically allocated memory. They help prevent memory leaks by automatically deallocating memory when it's no longer needed. The most common types are std::unique_ptr, std::shared_ptr, and std::weak_ptr.

What about lambda expressions?

Lambda expressions allow you to define anonymous functions directly in your code. They are useful for short, inline functions, especially when working with algorithms or callbacks.

How does the range-based for loop work?

The range-based for loop simplifies iterating over containers. Instead of using iterators, you can write for (auto& element : container) to access each element directly.
