How do I use advanced features of std::vector in C++?

What are some advanced features of std::vector in C++?

std::vector offers features like dynamic resizing, iterators, and algorithms for efficient data manipulation.

Can you explain how to use iterators with std::vector?

Sure! You can use begin() and end() methods to get iterators for traversing the vector. For example:

std::vector<int> vec = {1, 2, 3};
for(auto it = vec.begin(); it != vec.end(); ++it) {
    std::cout << *it << ' ';
}

What about using std::vector with algorithms?

You can use algorithms like std::sort and std::find directly with std::vector. For example:

std::sort(vec.begin(), vec.end());
auto it = std::find(vec.begin(), vec.end(), 2);

Are there any performance considerations I should be aware of?

Yes, frequent resizing can be costly. It's better to reserve space in advance using vec.reserve(size) if you know the size.
