Percabangan (Struktur If-Then sd Nested IF)

- PERCABANGAN (If – Then) merupakan struktur percabangan dimana suatu ekspresi akan dikerjakan bila kondisinya terpenuhi. Tetapi jika kondisinya tidak terpenuhi maka ekspresi di dalam struktur if tidak akan dijalankan dan blok If akan dilompati serta program akan melakukan tindakan berikutnya. Berikut Strukturnya : If (kondisi) Then … Ekspresi … End If • Kondisi : Berisi perbandingan antara satu variabel/konstanta dengan variabel/konstanta lain dengan menggunakan tanda <, >, =, <> dari suatu keadaan yang akan menghasilkan nilai “Benar” atau “Salah”. • Ekspresi : Rangkaian kode program (blok program) yang akan dijalankan jika kondisinya memenuhi syarat “Benar”. - PERCABANGAN (If – Then – Else) merupakan struktur percabangan di mana suatu ekspresi akan dikerjakan bila kondisinya terpenuhi. Tetapi jika kondisinya tidak terpenuhi maka ekspresi yang lainnya yang dikerjakan. Berikut Strukturnya : If (kondisi) Then … Ekspresi 1 … Else … Ekspresi 2 … ...
