If the condition evaluates to FALSE or NULL, the loop is bypassed, and control passes to the next statement. 如果条件的求值结果为FALSE或NULL,那么将绕过循环,并且控制被传递给下一条语句。
The GOTO label statement can unconditionally exit from a loop and transfer control to the executable statement or statement block that follows the specified statement label. GOTO标签语句可以无条件地退出循环,并将控制权转移到跟在指定的语句标签之后的可执行语句或语句块。
