<p>Цикл - це послідовність інструкцій, яка безперервно повторюється, поки не буде виконана певна умова у {{Glossary("computer programming","комп'ютерному програмуванні")}}. Прикладом може бути процес отримання елементу даних або його зміна, з перевіркою, що певна {{Glossary("conditional","умова")}} виконана, наприклад, що лічильник досяг прописаного значення.</p>
