Algoritma Struktur Data Per 1

Algoritma Struktur Data Per 1

Struktur Data & Algoritma - Pertemuan 1

Struktur Data & Algoritma Pemrograman

[cite_start]

Dosen: Alimin, M.Kom [cite: 2]

1. Pengenalan Program

[cite_start]

Program adalah sederetan perintah-perintah yang harus dikerjakan oleh komputer untuk menyelesaikan masalah[cite: 4].

[cite_start]

Level Bahasa Pemrograman[cite: 5]:

    [cite_start]
  • Tingkat Rendah: Bahasa mesin menggunakan kode numerik 0 dan 1[cite: 9, 10, 12]. [cite_start](+) Eksekusi cepat [cite: 14][cite_start], (-) Sulit dipelajari[cite: 15].
    • [cite_start]
  • Tingkat Menengah: Bahasa Assembly menggunakan simbol seperti ADD, SUB[cite: 16, 17, 19]. [cite_start](+) File kecil [cite: 21][cite_start], (-) Program sangat panjang[cite: 22].
    • [cite_start]
  • Tingkat Tinggi: Dekat dengan bahasa manusia (Pascal, C++, Java)[cite: 23, 25, 27]. [cite_start](+) Mudah dipelajari [cite: 28][cite_start], (-) Eksekusi lebih lambat[cite: 29].

2. Translator (Penerjemah)

[cite_start]

Translator berfungsi menerjemahkan bahasa tingkat tinggi ke tingkat rendah agar dimengerti mesin[cite: 30, 31].

[cite_start] [cite_start] [cite_start] [cite_start] [cite_start]
Metode Cara Kerja Kelebihan/Kekurangan
Interpreter [cite: 33]Diterjemahkan baris demi baris saat program jalan[cite: 34].Debugging cepat [cite: 36][cite_start], tapi eksekusi lambat[cite: 37].
Compiler [cite: 40]Seluruh program diterjemahkan sekaligus menjadi file .exe[cite: 41, 42]. Eksekusi cepat, namun proses kompilasi awal memakan waktu.

3. Algoritma

[cite_start]

Algoritma adalah sederetan langkah logis yang disusun secara sistematis untuk memecahkan masalah[cite: 45].

[cite_start]"Disebut logis karena setiap langkah bisa diketahui dengan pasti." [cite: 46]
[cite_start]

Syarat Algoritma[cite: 48]:

    [cite_start]
  • Tidak ambigu, tepat, dan pasti[cite: 49, 50, 51].
    • [cite_start]
  • Harus berhenti setelah langkah terbatas[cite: 52].
    • [cite_start]
  • Memiliki input (0 atau lebih) dan output (1 atau lebih)[cite: 53, 54].
    • [cite_start]
  • Harus efektif[cite: 55].

4. Notasi Algoritma

[cite_start]

Penulisan algoritma tidak tergantung pada bahasa pemrograman tertentu[cite: 60]. Ada 3 cara utama:

    [cite_start]
  1. Kalimat Deskriptif: Narasi langkah demi langkah[cite: 63].
    2. [cite_start]
  2. Flow Chart: Simbol visual alur program[cite: 85].
    3. [cite_start]
  3. Pseudo Code: Kode semu yang terdiri dari Judul, Deklarasi, dan Deskripsi[cite: 87, 88].

5. Tipe Data & Operator

[cite_start]

Tipe Data Utama[cite: 112]:

    [cite_start]
  • Bilangan Bulat: Integer, Longint, Byte[cite: 113].
    • [cite_start]
  • Logika: Boolean[cite: 114].
    • [cite_start]
  • Bilangan Real: Real, Single, Double[cite: 115].
    • [cite_start]
