Pernyataan Sementara

• continue — melompati eksekusi sisa loop body dalam iterasi saat ini dan melompat ke evaluasi ekspresi Boolean pernyataan while. Jika ekspresi bernilai true, maka loop berlanjut.
• break — segera menghentikan eksekusi iterasi saat ini dan mentransfer kontrol ke pernyataan pertama setelah perulangan. Dengan demikian, pernyataan ini mengakhiri eksekusi loop saat ini. Kami akan mempertimbangkannya secara lebih rinci di artikel berikutnya.

1. Jika ada apel di dalam mangkuk, maka kami menjalankan langkah 1.1 hingga 1.4:

   1. 1.1. Ambil sebuah apel
   2. 1.2. Kupas dan potong-potong
   3. 1.3. Atur irisan apel di kulit pai dalam wajan
   4. 1.4. Kembali ke langkah 1.

1. Jumlah irisan = 0

2. Selama jumlah irisan < 12, maka lakukan langkah 2.1 hingga 2.3

   1. 2.1. Potong apel lagi
   2. 2.2. Jumlah irisan++
   3. 2.3. Kembali ke langkah 2
