What are some examples of C++11 features?

C++11 introduced several new features. For example, auto keyword, range-based for loops, and smart pointers.

Can you explain the auto keyword with an example?

Sure! The auto keyword allows the compiler to automatically deduce the type of a variable. For example:

auto x = 5; // x is of type int
auto y = 3.14; // y is of type double

What about range-based for loops?

Range-based for loops simplify iterating over containers. For example:

std::vector<int> vec = {1, 2, 3};
for (auto& element : vec) {
    std::cout << element << ' ';
}

And smart pointers?

Smart pointers, like std::unique_ptr and std::shared_ptr, help manage memory automatically. For instance:

std::unique_ptr<int> ptr = std::make_unique<int>(10);
