Summary  
This chapter shows how to define enums to represent distinct categories of data and structs to encapsulate related properties, then combine them to model complex data types.  

General domain of usage  
Board game modeling (for example, representing pieces and positions in a chess game)

#define CATCH_CONFIG_MAIN
#include <catch2/catch.hpp>

struct Student {
    enum Level { Freshman, Sophomore, Junior, Senior };
    Level level;
};

bool isSenior(const Student& student);

TEST_CASE("isSenior returns true if the student's level is Senior", "[isSenior]") {
    Student s{ Student::Senior };
    REQUIRE(isSenior(s) == true);
}

TEST_CASE("isSenior returns false if the student's level is not Senior", "[isSenior]") {
    Student s1{ Student::Junior };
    Student s2{ Student::Sophomore };
    Student s3{ Student::Freshman };
    REQUIRE(isSenior(s1) == false);
    REQUIRE(isSenior(s2) == false);
    REQUIRE(isSenior(s3) == false);
}

Master the essentials of C++ structures and enumerations. Learn how to define, use, and combine structs and enums to model real-world data, and practice with hands-on coding tasks.

Explore the basics of structs in C++, including their syntax, initialization, and how they differ from classes.

Delve into more complex struct scenarios, including nesting and arrays.

Discover how enums provide named constants and how to use them effectively.
