The Complete Solidity Course - Zero to Advanced for Blockchain and Smart Contracts - Solution - How to Write Enums

The video tutorial introduces enums in programming, focusing on creating a shirt color enum with options like red, white, and blue. It guides through setting up a contract, creating functions like setwhite to change shirt colors, and handling errors in variable declarations. The tutorial also covers creating getchoice and getdefault choice functions, testing, and deploying the contract. It concludes with encouragement to practice and revisit the material for better understanding.
