Functional languages generally support first-class functions, which can be passed as callbacks to other functions, stored as data or returned from functions.
For instance, when the user clicks the close box, the window manager sends the delegate a windowShouldClose: call, and the delegate can delay the closing of the window, if there is unsaved data represented by the window's contents. Delegation can be characterized (and distinguished from forwarding) as late binding of self: [4]
In the delegate pattern, this is instead accomplished by explicitly passing the original object to the delegate, as an argument to a method.

With years of incremental progress, the NPVIC could soon become a real player in bypassing the unpopular presidential election process. Here's what you need to know about the effort.

Using such values can lead to unpredictable program behavior. Using non-owned memory: It is common to use pointers to access and modify memory.
