I am giving the Odin programming language a try, I decided to contribute Odin examples to Rosetta Code in the process.

Feel free to improve on the examples if some are not idiomatic Odin style (I'm still learning).

• Address of a variable

• Call a foreign-language function
• Check that file exists

• Draw a pixel
• Determine if a string is numeric
• Enumerations
• Factorial
• File input output
• Higher-order functions
• Inheritance/Single
• Memory allocation

• Singly-linked list/Element definition
• Singly-linked list/Element insertion
• Singly-linked list/Traversal
