What are some advanced techniques for using C++ vectors?

Advanced techniques for C++ vectors include using iterators, employing the reserve function for efficiency, and utilizing algorithms from the STL.

Can you explain how to use iterators with vectors?

Certainly! Iterators allow you to traverse the elements of a vector. You can use begin() and end() to get the start and end iterators.

What is the benefit of using the reserve function?

Using reserve() can improve performance by allocating memory in advance, reducing the need for multiple reallocations as the vector grows.

Are there any specific algorithms that work well with vectors?

Yes! Algorithms like std::sort, std::find, and std::copy are commonly used with vectors to manipulate and process data efficiently.

How can I remove duplicates from a vector?

You can remove duplicates by using std::sort followed by std::unique, and then resizing the vector to the new size.
