The Function Arguments page ( http://ca2.php.net/manual/en/functions.arguments.php ) has the following note: Note : As of PHP 5, default values may be passed by reference. Now, I assume this simply means that the following syntax is acceptable: function foo(&$bar = null){ // ... } However, again due to other inconsistencies, I was wondering if perhaps this pertains to something else. 回答1: It means that in PHP 4, using a

I am running dozens of bar graphs using R's ggplot2 and trying to follow our organizational style guide, which was developed using Excel manually for each graph. The maximum length bars are of different lengths in the different graphs and could change as the source data changes, so I don't want to manually set limits. [Perhaps there is a workaround here: is there a way to

In C, I simply placed a function that uses another function below that function, as closely as possible - that's pretty common. Like this: void bar() { } void foo() { bar(); } However, in C++, there are several types of functions: Free functions Private member functions Public member functions Static member functions I'm currently making my function order dependent on how they are ordered in the .hpp file, e.g.: class Foo_bar { public: Foo_bar(); void foo(); private: int some_member; void bar();

Is there a way to access the struct typedef BAR I defined in foo.c in test_foo.c without using a header file? So far, I was able to avoid a h file so that the whole program would consist of foo.c. Thanks. foo.c typedef struct BAR_{...} bar; BAR *bar_new(...) {..} test_foo.c extern BAR *bar_new(...) error: expected declaration specifiers or ‘...’ before ‘BAR’ 回答1: The answer is that there is one, and you should use an header file instead. You

Since the last update of chrome mobile for IOS, the address bar of the browser behaves differently. I'm sure you guys are aware of what I'm talking about: You scroll down your page, the bar hides up, but once you scroll up, it appears. Yes, it is a good user experience, I can tell. The problem is that I do have fixed element on top of my web app (header), and every time I scroll up, the address bar goes over my fixed element. I've lookup other web apps

There is nothing about it in the documentation. https://github.com/nnnick/Chart.js/tree/v2.0-dev/docsI don't know what to do. 回答1: Note that there seems to be some changes going on. The actual configuration would depend on which v2.0 you are using. For Version 2.0.0-alpha Set categorySpacing for the xAxes. You can do this globally Chart.defaults.bar.scales.xAxes[0].categorySpacing = 0 or you can do it by chart ... scales: { xAxes: [{ categorySpacing: 0 }], ... Fiddle - http

[...] For best results, use standard, system-provided interface elements and Auto Layout to construct your interface. All apps should adhere to the safe area and layout margins defined by UIKit, which ensure appropriate insetting based on the device and context. The safe area also prevents content from underlapping the status bar, navigation bar, toolbar, and tab bar. The problem is a

The code below creates the data plots the data incorrectly (bars are on top of one another) and then plots it correctly using a workaround of binding the dataframes together. library("ggplot2") x<-data.frame(dat=rep(seq(1
