function

问题 I have an array of bytes aka unsigned char called content . I want to split my content array into 2 new arrays in a separate function. This function should also determine the size for each of the 2 chunks and allocate memory for them. Also, I want to be able to use both the new arrays and their sizes outside of the function. My implementation is giving me segmentation fault and I must be doing something with pointers wrong. Main function int main(int argc, char *argv[]) { byte *content = NULL

问题 I've looked at a couple of questions but couldn't find a solution that doesn't use loops. I've looked here and here. Now, how could I add a progress bar that works exactly at the same time as this function: prog<-function(){ print("This is a test") Sys.sleep(05) setTxtProgressBar() } The above is a dummy function and I thought of using system.time to capture the time it takes for the print command to execute and use this for the progress bar. How could I make this work, without using a for

问题 I made a simple slideshow using only CSS, where on the radio button click, the margin of the element changes so it displays the desired slide. You can see how it works in the code snippet below. I also made this slideshow auto play with JavaScript. The script checks the next radio button in the list every 3 seconds. Now I need help to make the slideshow auto play in a loop and to also stop auto play when you check any radio button manually . $(document).ready(function() { function autoplay()

问题 Today I come to your aid in favor of optimizing some code! I was asked to solve a problem on a test a few weeks ago, and came up with this non-optimal solution since I'm beggining to learn Javascript. I wonder if there's a way (of course there is) to make this better. Here's the situation: "I am a particular kind person who has an infinite ammount of $2, $5 and $10 dollar bills, and I'm willing to change cash for anyone who wants it, BUT in the most efficient way, with the minimum ammount of

问题 As it currently stands, this question is not a good fit for our Q&A format. We expect answers to be supported by facts, references, or expertise, but this question will likely solicit debate, arguments, polling, or extended discussion.

I am aware of the partial function in functools , but how common is it in general python programs (not: Haskell, Erlang, Clojure etc )

问题 Below is the code that I'm working with. function my_tab( $tabs ) { // the following array will be created dynamically $colors = array("red", "white", "blue"); foreach ($colors as $value) { $tabs[$value] = array( 'name' => $value ); // start creating functions function content_for_[$value]() { echo "this is the " .$value. " tab"; } // stop creating functions add_action('content_for_'.$value, 'content_for_'.$value); } return $tabs; } As you can see, I have an array that's created dynamically.

问题 I'm following up on this answer . I'm wondering if there is a way to set the default for argument rug to FALSE and argument multiline to TRUE in the plots generated by library(effects) as, for example, shown below in the code? library(effects) m <- lm(Fertility ~ Examination*Education, data = swiss) plot(allEffects(m), rug = FALSE, multiline = TRUE) # By default, change `rug = FALSE` # `multiline = TRUE ` 回答1: I think if you're just trying to add those two options to @MrFlick's answer you

问题 I'm trying to figure out what's behind va_start(), va_arg() macroses. The code below works well. #include <iostream> #include <cstdarg> void f(double a, double b, ...) { va_list arg; va_start(arg, b); double d; while((d = va_arg(arg, double)) != 0) { std::cout << d << '\n'; } } int main(int argc, char *argv[]) { f(1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 0.0); return 0; } As I was expected it gave such output: 3 4 5 6 7 8 9. Then I found definitions of that macroses (in internet, cause my
