There are three ways to inherit interfaces and implementations, including:
1. Only inherit interface, pure virtual function;
2. Inherit interface and implement, allow overwrite (override), virtual function;
3. Inheritance interface and implementation, not allowed to overwrite (override), not virtual function;
1. Pure virtual function:
Only interfaces are inherited, but derived classes must implement their interfaces;
Pure virtual functions can a
description of the stack
The stack is a basic data structure. In the stack, the deleted element is the most recently inserted element, which implements a policy of LIFO (Last-in, first-out, LIFO).
There are only two--push and pops that change the way elements in the stack are manipulated. Push is pushing elements into the bottom of the stack, and pop is ejecting the elements from the top of the stack.
The following is the process of push and pop

7 Approaches for AOP in. Net
Seven methods for Implementing AOP in. NET
Here are all the ways that I can think of to add AOPto your application. This mostly focus on the interception side of things, because once you have that, everything else it just details.
Here we list all methods that I have come up with to add AOP
Android wants to achieve the display of the chart, very troublesome. Online search for the implementation of the scheme, there are no more than three kinds:1. Write your own canvas, slowly realize, request too high, difficult to fix.2. Use Achartengine Implementation, ugly, and very small extensibility. 3. Using WebView to load JS, although the theory will be more cost-effective, but the effect is good, and
The example in this paper describes the method of automating C # timer implementation. Share to everyone for your reference. The implementation method is as follows: The code is as follows: Here's a time to open the form to perform the button on the timer.private void Form1_Load (object sender, EventArgs e){System.Timers.Timer Ptimer = new System.Timers.Timer (5000);//Every 5 seconds, no winfrom comes withp

Figure 47 shows the implementation process of Volume Rendering using the ray projection algorithm.
First, we need to render the forward and backward surface depth graphs. This is to calculate the maximum distance of Ray traversing and serves as the basis for loop sampling control; then, the vertex position

The so-called RPC is a remote method call, or simply by mq,tcp,http or the network protocol you write to transmit what I want to call the other side of the interface, the other side processing and then return the results to me. That's a simple process.At runtime, a client-to-server RPC call, with an internal operation of roughly 10 steps, is as follows:1 . Calling client handle; executing transfer parameters2. call the Local system kernel to send network messages3. Message delivery to remote hos
