Working with struct and enum

There are several elementary types in solidity that can be used together to form various complex user-defined types. In this recipe, you will learn about two user-defined types in Solidity: struct and enum.

How to do it...

Let's create and work with various user-defined types using struct and enum.

Structs

Structs provide a way to define new types of solidity:

1. Use the struct keyword for creating user-defined types in solidity:

struct Person { }

2. Create a struct with a name and the associated properties inside it:

struct Person {
