Using Auto

You have now seen how to store basic types and vectors containing those types. As you practiced declaring variables, in each case you indicated the type of the variable. It is possible for C++ to do automatic type inference, using the auto keyword.

Have a look at the notebook below to see how this works.

Workspace

This section contains either a workspace (it can be a Jupyter Notebook workspace or an online code editor work space, etc.) and it cannot be automatically downloaded to be generated here. Please access the classroom with your account and manually download the workspace to your local machine. Note that for some courses, Udacity upload the workspace files onto https://github.com/udacity , so you may be able to download them there.

Workspace Information:

Default file path:
Workspace type: jupyter
Opened files (when workspace is loaded): n/a

On to an Exercise

Now that you have seen some exposure to variables and containers, test your knowledge in the next exercise! Before you go, be sure to have a careful look at the 2D vector example back in Storing Vectors , as you'll need this for the exercise.
