P.run ()
Fmt. Println (P.name ())
var p2 person = p. (person)/type assertion, interface type assertion to specific type
Fmt. Println (P2.age)
}
In addition, a type assertion return value can have a second bool value indicating whether the assertion was successful, as follows:
If p2, OK: = P. (person); OK {//Assertion success OK value is true
Fmt. Println (OK)
Fmt. Println (P2.age)
}
5. Define function type
The following is the definition of a function type handler

As soon as I woke up, I was bored. I was learning VB, so I could use VB to write a simple calculator! Consolidate the foundation...CodeAs follows:

of that I is 5 at the completion of the iteration, so it is printed five times 5 .To get the results we expect, we can assign I to a local variable to get rid of the effects of the outer iterations. for (var i = 0; i ) { (function (idx) { setTimeout (function c8> () { console.log (idx); 5); }) (i);}Manufacturing Function BuilderIf we are going to implement a series of functions: ADD10,ADD20. we have constructed a constructor named Adder

called, and the instances are isolated, containing the different reference environment sites at the time of invocation. Unlike functions, closures can have multiple instances at run time, and different reference environments and the same combination of functions can produce different instances. A, definition the closure in Python is defined (interpreted) as: if, in an intrinsic function, a reference is made to a variable in an outer scope (but not at the global scope), the intrinsic function
This section describes the development process for ActiveX controls, automation servers, or any other server that complies with COM specifications. The following example implements a simple Automation server that performs integer addition. We use the Setaddend () method to set the Addend value. Each time the sum () method is invoked, the Addend is added to the current result. We use GetResult () to get the result value and reset the value with clear (). The Java class used to implement this beha
Today, I used the coalesys webmenu for Asp.net control and found that the support for Chinese characters was too poor. It was garbled and dizzy! This is how others solve it!

Path. endswith ("Web "))Path = server. mappath ("../");String pathforwms = path + "\ usercontrol \ workermenu.

2. Participate in the operation of symbol bit
Second, how to achieve?We first take the clock as an example, assuming that the standard time is 4 points, and one clock is 7 points in the whole. We can rotate the hour counter counterclockwise by 3, or rotate the hour clockwise by 9 cells.
7-3=7+9=4 MoD (12)
The above equation is a congruence, and the

5. Implementation of the Undo operation
In command mode, we can call the execute () method of a command object to process the request. If you need to cancel the (UNDO) request, you can add a reverse operation to the command class.
ExtensionIn additionReverse operationIn addition to undo, you can also useSave the Historical Status of an objectThe latter can be implemented using the memento pattern.
The following uses a simple exam

The previous implementation of a number of addition/subtraction, counters, memory. Here we are going to use these results to implement a new, better-used adder. People are lazy, so if you want to add 100 numbers to the adder that you implemented earlier, this is very bad, because if there is an error in the middle step, you need to clear 0 and re-enter it again. So we can make use of the first storage and p

function map(array, func){ var res = []; for ( var i = 0, len = array.length; i
Running this code will print:2, 4, 6, 8, 9 // Add 1 to each element in the array [1, 3, 5, 7, 8]
Note the call of the map function. The second parameter of map is a function. This function has an effect on each of the first parameters (arrays) of map, but it may have no significance for code other than map. Therefore, we do not need to define a function for it.
