Tugas Pertemuan 3
Soal :
- Buatlah program untuk
menampilkan unsur dan melakukan proses sbb;
menu ; - menghitung volume kubus V= sxsxs
- menghitung luas lingkaran L= 22/7 x r x r
- menghitung volume silinder V =
22/7 x r x r x t
pilihan user (1~3) ; - buat program yang menerima input sebuah angka positif, kemudian menampilkan angka genap 0 sd angka tsb.
