What are the key features of C++11 that improve compatibility?

C++11 introduced several features like auto keyword, nullptr, and range-based for loops that enhance compatibility.

Can you explain how the auto keyword works in C++11?

Sure! The auto keyword allows the compiler to automatically deduce the type of a variable from its initializer, making code cleaner.

What is nullptr and why is it better than NULL?

nullptr is a type-safe null pointer constant introduced in C++11, which helps avoid ambiguity that can arise with NULL.

How do range-based for loops simplify iteration?

Range-based for loops allow you to iterate over containers without needing iterators, making the code more readable and concise.

Are there any compatibility issues when using C++11 features?

Some older compilers may not fully support C++11 features, so it's important to check compatibility with your development environment.
