How do I use vectors in C++?

How do I use vectors in C++?

In C++, vectors are part of the Standard Template Library (STL). You can include the vector header and use it like this: #include <vector>.

What are the advantages of using vectors over arrays?

Vectors are dynamic in size, meaning they can grow and shrink as needed, while arrays have a fixed size.

Can you show me an example of how to add elements to a vector?

Sure! You can use the push_back() method to add elements. For example: myVector.push_back(10); adds the value 10 to the end.

How do I access elements in a vector?

You can access elements using the index, like myVector[0] for the first element. Just remember that indexing starts at 0!
