问题 Code below taken from here. * qsort example */ #include <stdio.h> #include <stdlib.h> int values[] = { 40, 10, 100, 90, 20, 25 }; int compare (const void * a, const void * b) { return ( *(int*)a - *(int*)b ); } int main () { int n; qsort (values, 6, sizeof(int), compare); for (n=0; n<6; n++) printf ("%d ",values[n]); return 0; } We have a compare function with parameters in its signature but when we call it in qsort no arguments are passed. How are the values of a and b passed to the function

问题 My aim: To use a password in jenkins which is masked after input and runtime. I only need it for my job. I can use it in my java code to login to a website. Areas I have looked at: The credentials plugin - this looks like the right area (but I'll need to get the sysadmins to add me as its locked down). Also I can't find out how you can access the output? 回答1: Have a look into the EnvInject plugin, there you can define password parameters that are masked in console output and job configuration

问题 We have a structure like below: template<size_t size> class Container{ public: char characters[size]; }; And we have a function like below: template <size_t size> void function(Container<size> input,size_t Size){ //all instances do exactly same thing and with regard to Size that determines the size of object } Now in C++ for every value of size, a different instance of function will be created and apparently that's not right in this case since all instances do the same thing, to avoid this

问题 Consider the following situation: Content MyScript.ps1 : Param ( [String]$CountryCode, [String]$FilesPath, [String]$KeepassDatabase, [String]$KeepassKeyFile, [String]$EventLog = 'HCScripts', [String]$EventSource, [HashTable]$CitrixFarm = @{'Server1' = '6.5'} ) $CountryCode $FilesPath $KeepassDatabase $KeepassKeyFile $EventLog $EventSource $CitrixFarm Content of the Caller.ps1 : Param ( $FilesPath = ".\MyScript.ps1", $EvenntLog = 'Test', $CountryCode = 'BNL', $KeepasDatabase, $KeepasKeyFile )

问题 In PHP, how can I pass an Object (actually an Array) from one Site to another Site (by not losing its original Object Structure and Values)? How to PASS/SEND from the host site NOT to pull from the destination site I want to pass directly from the automated script by NOT using HTML and web forms. Any suggestion, please. 回答1: The best way to do that is to use json_encode() : file_get_contents('http://www.example.com/script.php?data='.json_encode($object)); on the other side: $content = json

问题 I had tried to create method and call it from another file to the main class but It won't work the error message said "java.lang.NullPointerException" Main.class Keywords kw = new Keywords(); @When("^gmailDD$") public void gmailDD() throws Throwable{ WebDriverWait wait5s = new WebDriverWait(driver, 5); String regis = "/html/body/div[2]/div[1]/div[5]/ul[1]/li[3]/a"; String dd = "/html/body/div[1]/div/footer/div/div/div[1]"; String empty = "/html/body/div[1]/div/footer"; kw.clickbyxpath(regis);

问题 I have this function to compute some sort of polynomial: def pipoly(df,pj): n=np.size(pj) p=pj[0] for j in range(1,n): p+=pj[j]*df**j return p pj is supposed to be an array that contains the initial guesses of the coefficients of the polynomial; the degree of the polynomial is hence determined by the function itself in the first line. df is a scalar variable. This function is passed to scipy.optimize's curve_fit as parfit,covfig=curve_fit(pipoly,[f-f0[j] for f in f_df[if0[j]:if0[i]]], pmode

问题 I am using Nodejs . Server.js app.get('/dashboard/:id', routes.dashboard); Routes / index.js exports.dashboard = function(req, res){ } I want to be able to pass the 'id' variable from app.js to the dashboard function . How do I go about doing this ? 回答1: Assuming ExpressJS, you shouldn't need to pass it. For each parameter placeholder (like :id ), req.params should have a matching property holding the value: exports.dashboard = function (req, res) { console.log(req.params.id); }; Though, this
