+Penjelasan Program Hands On OOP
+Nama : Melati Anggraini ID GDSC : 220020111 Kampus : ITB
+
+Bahasa
+Bahasa yang digunakan adalah C++
+Versi compiler: C++ 17
+Deskripsi Singkat Tugas
+Program ini saya beri judul "Mesin ATM".
+Pembuatan program ini dimulai dengan class atm.
+Ada class saving yang merupakan turunan dari class atm.
+
+Cara Menjalankan Program
+Pertama, user akan memasukkan PIN dan Account Number. Jika sudah sesuai, maka user akan diberi 5 piihan menu yaitu menu Check Balance, Cash Withdraw, Show User Details, Update Mobile No, dan Exit. Jika sudah selesai user akan kembali ke menu awal.
+
+Design Pattern yang Digunakan
+Decorator (Structural Pattern)
+Decorator
+Penjelasan: Dekorator merupakah pola struktural yang memungkinkan menambah perilaku baru yang dapat menempatkan fungsi baru secara dinamis tanpa mengubah strukturnya.
+Letak Implementasi: method setMobile() dan method cashWithDraw (pada line 59 - line 83)
+Alasan Pemilihan: agar dapat mengupdate mobile number dengan pengecekan nomor sebelumnya(mobileNo)dan bisa menarik uang dengan pengecekan balance yang tersedia sehingga dua proses ini tidak akan mengubah struktur di fungsi utama.
