Exception handling memisahkan penanganan kondisi galat tidak terduga dari alur logika utama aplikasi agar program tidak langsung terhenti tiba-tiba (crash).
Poin Kunci Materi:
- Blok
try: Membungkus blok instruksi yang berisiko memicu eksepsi. - Keyword
throw: Melempar objek exception (seperti std::runtime_error) saat anomali terdeteksi. - Blok
catch: Menangkap objek exception dengan referensi const std::exception& e dan memanggil e.what().
