How do I use vectors in C++?

Vectors in C++ are part of the Standard Template Library (STL). They are dynamic arrays that can resize automatically.

Can you show me how to declare and initialize a vector?

Sure! You can declare a vector like this: std::vector<int> myVector; To initialize it, you can use: std::vector<int> myVector = {1, 2, 3};.

What are some common operations I can perform on vectors?

Common operations include adding elements with push_back(), removing elements with pop_back(), and accessing elements using the [] operator.

How do I iterate through a vector?

You can use a for loop like this: for(int i = 0; i < myVector.size(); i++) { std::cout << myVector[i] << ' '; }.
