Congratulations! In this lesson, you learned about how data types and variables work in C#. Topics covered include:

• C# built-in data types, including int, double, char, string, and bool
• How to create, name, and use variables
• Common errors you might encounter
• Converting data types from one to another

For more information on using types and declaring variables, check out Microsoft’s C# documentation.

Want to keep track of the different data types? Download this handy cheatsheet.

Now that you know a few things about variables and data types, try writing a program that:

• Converts a boolean to a string
• Changes a string to a list of chars
• Converts a data type we didn’t cover to another data type!
