Vectors

Review

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

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.

### Instructions

**1.**

**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
