How can I modernize my C++ code?

How can I modernize my C++ code?

You can start by using features from C++11 and later, like smart pointers, range-based for loops, and auto keyword.

What are smart pointers and how do they help?

Smart pointers manage memory automatically, preventing leaks. They include std::unique_ptr and std::shared_ptr.

Can you give me an example of using a range-based for loop?

Sure! Instead of a traditional for loop, you can write: for (const auto& item : container) { /* use item */ }.

What other modern features should I consider?

Consider using lambda expressions, the std::thread library for concurrency, and the std::optional for better handling of optional values.
