/*
# Structs (Strcutures) is a value type data structure in C#
# Unlike classes, structs are value types rather than reference types.
# It is similar to a class because it can contain constructors, methods, and fields
# It represents lightweight objects that encapsulate data
# Common use: Designing small, data-focused types.
# Sintaxe:
  struct <struct_name>
  {
      // Fields
      // Methods
  }
