PEMROGRAMAN DASAR BAB 4 : TIPE DATA ARRAY

Laporan Praktikum Pemrograman Dasar Bab IV Fakultas Ilmu Komputer Universitas Brawijaya 2016/2017

Soal :
1. Buatlah program dengan pilihan menu yang terus berulang, dan menu akan berhenti jika user akan      menginputkan angka “ 7 ”.
    Pilihan menunya adalah :
   1. Input Data
   2. Lihat Data
   3. Average
   4. Sum
   5. Max
   6. Min
   7. Keluar
   Masukkan nilai : 

2. Buatlah program dengan pilihan menu yang terus berulang, dan menu akan berhenti jika user akan      menginputkan angka selain yang diminta. Program ini memiliki array 2D untuk menyimpan data        Kereta Api.
 
 





    Pilihan menunya adalah :
    1. Melihat Daftar Kereta Api
    2. Melihat Daftar Kereta Api yang ada AC
