Imam Ibnu Badri Algoritma dan Pemrograman 05.52

Studi Kasus

Membuat program untuk menghitung biaya menginap di hotel dengan ketentuan. Gunakan percabangan, perulangan, array, struct, prosedur dan fungsi.

Jenis kamar yang tersedia antara lain :

VVIP ⇛ 1 juta/malam
VIP ⇛ 500 ribu/malam
Switt ⇛ 250 Ribu/malam

Fasilitas Tambahan

Extra Bed Besar ⇛ 75 ribu/malam
Extra Bed Kecil ⇛ 50 ribu/malam
Laundry Expres ⇛ 20 ribu/malam
Dry Cleaning ⇛ 30 ribu/malam
Lunch ⇛ 50 ribu/malam

Pertama-tama program meminta inputan data diri berupa nama, alamat dan nomer handphone. Kemudian program meminta inputan jenis kamar dan lama menginap. Setelah itu, program akan menanyakan, apakah ingin meminta fasilitas tambahan ?

Apabila iya, maka muncul menu fasilitas tambahan. Kemudian akan diminta menginputkan beberapa jenis fasilitas tambahan, Jenis Fasilitas dan jumlahnya. Program akan menampilkan data diri, total biaya kamar, total biaya fasilitas tambahan dan total yang harus dibayar.
