It depends at what time you call for the function in the class. Notifications are very easy. You declare a global name (outside of any class) public static let kNotification = Notification.Name("kNotification") In AppDelegate, you post notification (instead of calling the function) let nc ...

Declaring Function Pointers: Function pointers are declared by specifying the return type and parameter types they point to. For example, to declare a function pointer to a function that takes an integer and returns a float, you would usefloat (*funcPtr)(int). ...
In C, we can declare a static function. A static function is a function which can only be used within the source file it is declared in. So, as a conclusion, if you need to call the function from outside, you must not define the function as static. *From f...

By using GCC, C, and C++ compilers the code will be generated, and assertions are enabled by default. If we are unable to use the assert() function, we must be disabled, so ndebug should be defined. It was decided to declare it using #define NDEBUG code; otherwise, the code compilatio...
Enter to Rename, Shift+Enter to Preview Explanation: Age, height, and name are the three variables we declare in this program. We give his name as Paul, 1.74 as his height, and 23 as his age. The values of these variables are then printed out in a message using the cout instruction....
In Delphi, the versatile web-programming language,arraysallow a developer to refer to a series of variables by the same name and to use a number—an index—to tell them apart. In most scenarios, you declare an array as a variable, which allows for array elements to be changed at run-ti...
