Enumerasi (Enum) adalah tipe data bentukan khusus yang nilainya dibatasi pada sekumpulan konstanta bernama yang sudah ditentukan sebelumnya.
Poin Kunci Materi:
- Keterbacaan Kode: Menggantikan angka magic number (seperti 0, 1, 2) dengan nama deskriptif seperti OFFLINE, ONLINE.
- Modern Scoped Enum:
enum class mencegah polusi namespace dan melarang konversi implisit ke integer. - Type Safety: Mencegah bug kesalahan perbandingan antar enum berbeda.
