如果条件为false,则循环将在此处结束。do while 因此,两者之间的区别在于,循环至少执行一次语句集。do while Syntax while(<condition>)begin// Multiple statementsenddobegin// Multiple statementsendwhile(<condition>); Example #1 - while loop moduletb;initialbeginintcnt =0;while(cnt <5)begin$display("cn...

Case2 (Always FALSE condition): Variables ‘i’ is initialized before ‘do-while’ loop to ‘20’; iteration is increment of counter variable ‘i’; condition is FALSE always as ‘0’ is provided that causes NOT to execute loop statements, but it is noted here in output that loop stateme...
Then instead of writing the print statement 100 times, we can use a loop. That was just a simple example; we can achieve much more efficiency and sophistication in our programs by making effective use of loops. There are 3 types of loops in C++. for loop while loop do...while loop ...
Complete tutorial on While and Do While in JAVA with examples. The While is a type of loop which evaluate the condition first. If condition evaluate to true the code inside the block{} will be executed and if it evaluate to false it will jump outside the
上一篇聊过了以指定次数执行语句的FOR NEXT循环,但是当我们不知道循环具体会运行多少次,但能通过某种条件的变化来实现控制循环的开始和结束,这便是今天咱们要聊聊的的DO…Loop循环。 一、当条件为 True 时重复语句 语法: 1.条件前置 Do While 条件表达式 ...
2. do – while loop in C It also executes the code until the condition is false. In this at least once, code is executed whether the condition is true or false but this is not the case with while. While loop is executed only when the condition is true. ...
