The break statement Thebreakstatement terminates the execution of the nearest enclosing do, for, switch, or while statement in which it appears. The execution of the program passes to the statement that follows the terminated statement. C break with while In the following example, we use abreak...

while (expression)statement Theexpressionmust have arithmetic or pointer type. Execution proceeds as follows: Theexpressionis evaluated. Ifexpressionis initially false, the body of thewhilestatement is never executed, and control passes from thewhilestatement to the next statement in the program. ...
The do-while statement can also terminate when a break, goto, or return statement is executed within the statement body.This is an example of the do-while statement:复制 do { y = f( x ); x--; } while ( x > 0 ); In this do-while statement, the two statements y = f( x )...
At any point within the body of an iteration statement, you can break out of the loop using thebreakstatement. You can step to the next iteration in the loop using thecontinuestatement. Theforstatement Theforstatement executes a statement or a block of statements while a specified Boolean expr...
statement1 1. 2. 当expression 条件满足时,执行 statement1 语句, 语句执行完后,会返回第一行继续判断条件是否满足。如果该条件一直保持满足状态,循环语句无法退出,就会出现死循环的状态。 while True: print("hello, you") 1. 2. 为了让程序运行到一定阶段退出循环体,需要改变条件,当条件改变到不满足的状态时...
