问题 As you can see below here is a copy of my script what I've created, could someone help me improve/fix my currenttime tasks. Basically, during the day periodically calls test every 3 mins +- 60 seconds each periodically cycle it is supposed to do the follow tasks: Anywhere during 23:30:00 to 23:40:00 it turns clearscreen to false Anywhere during 23:40:00 to 23:50:00 it checks if clearscreen is false and if it is then it clears certain files and then it immediately sets clearscreen to false

Strange result using recursion with while loop

问题 I'm a beginner in Javascript. And while trying recursion by myself, i got some strange result using while loop. And just the right result using If statement. Here's the code and the result : var test = function f(n){ while(n > 0){ document.write(n); f(--n); } }; test(5); And the result : 5432112113211211432112113211211 While using If statement var test = function f(n){ if(n > 0){ document.write(n); f(--n); } }; test(5); The result is : 54321 I can't really debug it in the while case. It gets

问题 I saw something with a similar title has been answered, but the content was too dense for me as I don't know a lot of c++. I am very new to programming, I cannot figure out how to store the previous iteration in my while loop. I am trying to use a while loop to write a users text into a file, and end their input with two \n characters. This is where my problem is because with my current code the input ends with one instance of enter. My code looks like this, but I know temp and new_advice are

问题 This question already has answers here : How to clone or copy a list? (16 answers) Closed 2 years ago . Python/programming newbie here, trying to figure out what is going in with this while loop. First the code: var_list = [] split_string = "pink penguins,green shirts,blue jeans,fried tasty chicken,old-style boots" def create_variations(split_string): init_list = split_string.split(',') first_element = init_list[0] # change first element of list to prepare for while loop iterations popped =

Scala while loop returns Unit all the time

北战南征 提交于 2020-01-15 03:13:29
问题 I have the following code, but I can't get it to work. As soon as I place a while loop inside the case, it's returning a unit, no matter what I change within the brackets. case While(c, body) => while (true) { eval(Num(1)) } } How can I make this while loop return a non-Unit type? I tried adding brackets around my while condition, but still it doesn't do what it's supposed to. Any pointers? Update A little more background information since I didn't really explain what the code should do,

问题 Is there a way to break out of a while loop before the original condition is made false? for example if i have: while (a==true) { doSomething() ; if (d==false) get out of loop ; doSomething_that_i_don't_want_done_if_d_is_false_but_do_if_a_and_d_are_true() ; } Is there any way of doing this? 回答1: Use the break statement. if (!d) break; Note that you don't need to compare with true or false in a boolean expression. 回答2: break is the command you're looking for. And don't compare to boolean

问题 I'm working on a WordPress posts loop with same rows repeating. I achieved the first row but the 2nd row isn't looping whereas the first row loops perfectly. Below is the code for the loop and the screenshot. Loop Code $count = 1; $featured_posts = new \WP_Query( $args ); if ( $featured_posts->have_posts() ) : while ($featured_posts->have_posts()) : $featured_posts->the_post(); if ( 1 == $count % 5 ) { echo '<div class="wh-tiles-posts-left">'; } elseif ( 2 == $count % 5 ) { echo '<div class=
