What are advanced vector techniques in C++?

Advanced vector techniques in C++ include methods like resizing, reserving space, and using iterators for efficient data manipulation.

Can you explain how to use iterators with vectors?

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

What is the difference between push_back and emplace_back?

push_back adds a copy of an element to the end, while emplace_back constructs an element in place, which can be more efficient.

How do I sort a vector of custom objects?

You can use std::sort with a custom comparator. Define a comparison function or lambda that specifies the sorting criteria.

Are there any performance considerations I should be aware of?

Yes, consider the cost of resizing and copying elements. Using reserve() can help optimize performance when you know the size in advance.
