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.



Optional: Write a program to find the sum of even numbers and the product of odd numbers in a vector.

For example:

Suppose we have a vector that is {2, 4, 3, 6, 1, 9}.

Then the program should output:

Sum of even numbers is 12 Product of odd numbers is 27
