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...
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. ...
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 looking for....
Q: There is no difference between while and for loops (T/F) ?True or false (click to find out) False: You can use a do while loop to execute a block always once which is not possible with a for loop. This is only true in trivial form - you can write code to detect the ...

< 10. With i++ (postfix incrementing) the one is added after the test i < 10. In case of a for loop this make no difference, but in while loop test it makes a difference. But before we look at a postfix and prefix increment while loop example, we first look at the while loop...
For loop: When it is desired to do initialization, condition check and increment/decrement in a single statement of an iterative loop, it is recommended to use 'for' loop.
Difference between for and while loop in C, C++, Java for循环: for 循环提供了一种编写循环结构的简洁方式。与 while 循环不同,for 语句在一行中使用初始化、条件和递增/递减,从而提供了一种更短、更易于调试的循环结构。 语法: for(initialization condition;testing condition; ...
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...
For loop– For loops are used to sequentially iterate over a python sequence. When the sequence has been iterated completely, the for loop ends and thus executes the next piece of code. The While Loop In Python The while loop statement is used to repeat a block of code till a condition ...
