Congratulations! You have learned about how to store groups of data into vectors in C++. 🙌

Here are some of the things that we learned:

• Vectors are a sequence of elements that you can access by an index.

  std::vector<int> even = {2, 4, 6, 8, 10};

• The first index in a vector is 0.

• Some of the functions that come with vectors:

  • .push_back()
  • .pop_back()
  • .size()

• We can use a for loop to iterate through a vector.
