statement(s)inside while block are executed. Theconditionis checked again. If it evaluates to true, thestatement(s)inside the while loop are executed. This cycle goes on. If at all, the condition evaluates to false, execution comes out of while loop, meaning while loop is completed. And ...
For loop: It allows users to execute a block of code a specific number of times. While loop: It allows users to execute a block of code if a specific condition is true. Do-while loop: This allows users to execute a block of code at least once and then repeatedly execute it if a ...
块作用域一般用于控制流,比如 if,while 和 for 循环。但是拥有块作用域的语言一般都会允许使用“裸露”的块,这样就可以在块中定义辅助变量并使用,在块终结时销毁。 块可以用来隐藏名字绑定。如果在块的外面定义了 n,在块的里面也可以定义名叫 n 的变量,它会遮盖外面的 n。但是这样的风格一般被认为是不好的,因...
body of while loop goes here, using l1val and l2val instead of l1[i] and l2[i] *-They don't really stop automatically - the list iterator raises the exception StopIteration, which is caught by the for loop as a signal to stop looping. My crystal ball is getting fuzzier, but there...

"break" is used in a for loop, do/while and while loop and a switch. An "else" statement is not something that you can break out of. It just ends. Even if you add the (;) after "break" it is still an error. Andy Jul 3, 2021 at 7:49am ...
