1. Struktur switch\u2013case<\/code><\/h2>\n\n\n\n

Apa Itu switch\u2013case<\/code>?<\/h3>\n\n\n\n

switch<\/code> digunakan jika kita ingin memeriksa banyak kemungkinan nilai<\/strong> dari satu variabel<\/strong>.
Struktur ini sangat berguna saat membuat menu, pilihan angka, atau sistem kategori.<\/p>\n\n\n\n

\n\n\n\n

Struktur Umum<\/h3>\n\n\n\n
switch (variabel) {\n    case nilai1:\n        \/\/ kode jika variabel == nilai1\n        break;\n    case nilai2:\n        \/\/ kode jika variabel == nilai2\n        break;\n    default:\n        \/\/ kode jika tidak ada yang cocok\n}\n<\/code><\/pre>\n\n\n\n
\ud83e\udde0 Keterangan:<\/strong><\/p>\n\n\n\n
    \n
  • case<\/code> berfungsi seperti \u201ckondisi\u201d.<\/li>\n\n\n\n
  • break<\/code> menghentikan eksekusi agar tidak lanjut ke case berikutnya.<\/li>\n\n\n\n
  • default<\/code> opsional, digunakan jika tidak ada kondisi yang cocok.<\/li>\n<\/ul>\n\n\n\n
    \n\n\n\n
    Contoh: Menu Hari dalam Seminggu<\/h3>\n\n\n\n
    #include <iostream>\nusing namespace std;\n\nint main() {\n    int hari;\n    cout << \"Masukkan angka 1\u20137 untuk hari: \";\n    cin >> hari;\n\n    switch (hari) {\n        case 1:\n            cout << \"Senin\" << endl;\n            break;\n        case 2:\n            cout << \"Selasa\" << endl;\n            break;\n        case 3:\n            cout << \"Rabu\" << endl;\n            break;\n        case 4:\n            cout << \"Kamis\" << endl;\n            break;\n        case 5:\n            cout << \"Jumat\" << endl;\n            break;\n        case 6:\n            cout << \"Sabtu\" << endl;\n            break;\n        case 7:\n            cout << \"Minggu\" << endl;\n            break;\n        default:\n            cout << \"Angka tidak valid!\" << endl;\n    }\n\n    return 0;\n}\n<\/code><\/pre>\n\n\n\n
    Output<\/h3>\n\n\n\n
    Masukkan angka 1\u20137 untuk hari: 5\nJumat\n<\/code><\/pre>\n\n\n\n
    \n\n\n\n
    2. Operator Ternary (?:<\/code>)<\/h2>\n\n\n\n
    Apa Itu Operator Ternary?<\/h3>\n\n\n\n
    Operator ternary digunakan untuk kondisi singkat<\/strong>, menggantikan bentuk sederhana dari if\u2013else<\/code>.<\/p>\n\n\n\n
    Strukturnya seperti ini:<\/p>\n\n\n\n
    kondisi ? nilai_jika_benar : nilai_jika_salah;\n<\/code><\/pre>\n\n\n\n
    Contoh 1<\/h3>\n\n\n\n
    int umur = 20;\nstring status = (umur >= 17) ? \"Dewasa\" : \"Belum Dewasa\";\ncout << \"Status: \" << status << endl;\n<\/code><\/pre>\n\n\n\n
    Output<\/h3>\n\n\n\n
    Status: Dewasa\n<\/code><\/pre>\n\n\n\n
    Contoh 2<\/h3>\n\n\n\n
    int angka;\ncout << \"Masukkan angka: \";\ncin >> angka;\ncout << ((angka % 2 == 0) ? \"Genap\" : \"Ganjil\") << endl;\n<\/code><\/pre>\n\n\n\n
    \n\n\n\n
    3. Perbandingan if\u2013else<\/code> vs switch\u2013case<\/code><\/h2>\n\n\n\n
    Kriteria<\/th>if\u2013else<\/th>switch\u2013case<\/th><\/tr><\/thead>
    Bisa pakai kondisi kompleks (><\/code>, <<\/code>, ==<\/code>)<\/td>\u2705 Ya<\/td>\u274c Tidak (hanya cocok untuk nilai tetap)<\/td><\/tr>
    Mudah dibaca untuk banyak pilihan nilai<\/td>\u274c Kadang panjang<\/td>\u2705 Lebih ringkas<\/td><\/tr>
    Bisa pakai tipe string<\/code><\/td>\u2705 Ya<\/td>\u274c Tidak (hanya int\/char\/enum)<\/td><\/tr>
    Wajib pakai break<\/code><\/td>\u274c Tidak<\/td>\u2705 Ya<\/td><\/tr><\/tbody><\/table><\/figure>\n","protected":false},"excerpt":{"rendered":"
