C++ Continue Statement Confusion

由 不羁的心 提交于 2021-02-16 20:44:35
问题 Background I was reading an old C++ primer that I have had lying underneath my bed for a few years. While reading a particular chapter, I happened to come across the " continue " statement. I read the information in the book about it; however, the book was a little short on details. I, being curious, wanted to test the continue statement to see if I could figure out more about it on my own (although it may be obsolete now, I still am curious on how it works). Problem I read that the continue

Python: Using continue in a try-finally statement in a loop

由 青春壹個敷衍的年華 提交于 2020-12-04 15:16:04
问题 Will the following code: while True: try: print("waiting for 10 seconds...") continue print("never show this") finally: time.sleep(10) Always print the message "waiting for 10 seconds...", sleep for 10 seconds, and do it again? In other words, do statements in finally clauses run even when the loop is continue -ed? 回答1: From the python docs: When a return, break or continue statement is executed in the try suite of a try...finally statement, the finally clause is also executed ‘on the way out

问题 Closed . This question is opinion-based. It is not currently accepting answers. Want to improve this question? Update the question so it can be answered with facts and citations by editing this post. Closed 6 years ago . Improve this question I was browsing through questions regarding continue keyword to get a better understanding of it and I stumbled upon this line in this answer These can be maintenance timebombs because there is no immediate link between the "continue"/"break" and the loop

问题 This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet. For help making this question more broadly applicable, visit the help center. Closed 7 years ago . Can someone explain why the else: pass shown below is needed in order for the rest of the code (the final print 'processing... statement) to be executed?

1、abstract 　　abstract修饰类，表示抽象的意思，抽象类可以含有非抽象变量和成员变量，也可以有普通方法和构造方法，但是不能被实例化（接口），但是可以被子类继承。 public abstract class AbstractList<E> extends AbstractCollection<E> implements List<E> { ... } 　　abstract修饰方法，表示抽象方法，抽象方法必须位于抽象类中，并且不能有具体实现。 abstract public E get(int index); 2、break 　　break在switch中用于跳出switch块，停止switch向下穿透的现象。 case value:expression; break; 　　break在循环中用于跳出循环。 while(...){ ... break; } 　　break也可以在后面接标签，用来跳出一些嵌套比较复杂的循环中。 flag: for(...){ for(...){ break flag; } } 3、continue 　　continue用于在循环中跳过本次循环。 while(...){ ... continue; } 　　continue也可以在后面接标签，在一些嵌套比较复杂的循环中跳过一次循环。 flag: for(...){ for(...){
