A. For loop is used for definite iterations while while loop is for indefinite iterations. B. For loop is faster than while loop. C. While loop can only be used with numbers while for loop can be used with any data type. D. There is no difference. ...
while loop can run indefinitely C. for loop is more complex D. none of the above 相关知识点: 试题来源: 解析 B。本题考查 for 循环和 while 循环的主要区别。while 循环可以根据条件无限运行,而 for 循环通常有明确的循环次数限制。选项 A 不准确,不能说 for 循环总是更快。选项 C 不准确,不一定...
保证了至少执行do{ }内的...循环,进入循环后,当条件不满足时,执行完循环体内全部语句后再跳出(而不是立即跳出循环) 三、执行次数不同do-while循环是先执行后判断,执行次数至少为一次。for循环是先判断后执行,可以不执行 循环语句 5.回到第二步继续执行流程 注意事项 1.表达式的值为boolean类型,并且如果循环体...
We use FOR to iterate over a known range of values and WHILE to evaluate an expression. for (initialization; termination; increment) { statement(s) } while (expression) { statement(s) } The difference between WHILE and DO WHILE is that on WHILE it checks the condition first, than execute...
VBA Do While Loop Syntax of Do While Loop In VBA Difference Between the two Do While Syntaxes How Does a Do While Loop Work Flow Diagram of a Do While Loop In VBA: Few Simple Examples of Do While Loop In VBA Writing a Nested Do While Loop Infinite Loop Using a Do While Loop How ...
Difference Between while and do...while LoopThe while loop differs from the do-while loop in one important way — with a while loop, the condition to be evaluated is tested at the beginning of each loop iteration, so if the conditional expression evaluates to false, the loop will never ...
While condition: expression(block of code) Unlike thefor loop, thewhile loopdoesn’t iterate over a sequence. It uses the comparison operators and booleans for its condition. Let’s look at some examples to better understand how it is used. ...
The do...while loop is almost the same as while loop except for one difference.As an important point, the do...while loop is always executed at least once, unlike the other loops. This happens because the loop runs for the first time and then at the end, the condition is checked to...
because you wrote : "while t<40" which does not include the 40, it self. But "for" contains the upper bound, which is 40. In other word, your first loop is done 4000 times, however, the "for" loop runs 4001 times. This may be the main result of difference that you are lookin...
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 ...
