Otherwise, applications that embed the IP address in the message data will not work properly.Three ways to implement NAT:There are three ways to implement NAT, namely static translation of the statically NAT, dynamic NAT and Port multiplexing overload.Static conversion refers to the conversion of the private IP addr
I recently used Java to simulate a Chinese Pinyin input method. The reason for this is that this input method can only be entered in a specific text box (written in Java ). In order to realize the recognition of consecutive pinyin sequences, hmm is used as a model, and the famous Viterbi algorithm is also a classic application of dynamic planning. I do not need to explain this algorithm, the Internet has its own talents. In order to find the observed sequence (the first step in modeling) for bui

Part five negotiation expert advantage cheatsStrength, control, and influence are the things everyone pursues when they interact with others. Isn't it? When negotiating, the most influential of these fires is that the most powerful side tends to force the opponent to make more concessions in the negotiations. If you are willing to let your opponent manipulate or influence you, it is clear that you will not be able to get the results you want. On the other hand, you can control the situation in y

Things to do today:"C + + primer, 5E"Pages 53rd to 58th, notes:1, a very good reference must not bind a const object. Example const int CI = 1024; const int R1 = CI;2, constant references do not necessarily bind const objects. example int i = 42; const int R1 = i;A constant reference is similar to the holder of an object, restricting the manipulation of the object being held.3, distinguish between pointer to const and const pointer declaration way.

The global const in C has an external link, in C + + He has internal links
Const double pi=3.14159 in C + +;
Equivalent to the static const double pi=3.14159 in C;
The premise is both outside of all functions
C + + 's intention is to make it easier to use const in header files
In C + + you can use extern to make a const value have an external link

With the rapid development of Internet network, the shortage of IP address has become a very prominent problem. In order to solve this problem, there are many solutions. The following are some of the more effective ways to address translation (NAT) in the current network environment.
Nat settings can be divided into static address translation, dynamic address translation, and multiplex dynamic address conversion.
1. Static address Translation applicable environment
Static address translation

Most of them can apply for multiple C-class legal addresses, because the campus network will have a large number of home page connections, some users may be due to the public address is not enough to use private address. Such users can directly access cernet resources without address translation, and cernet users require direct access to those users. In order to distinguish the two kinds of users of cernet, the cernet referred to as the

A "valid" input is a real number within the [ -1000,1000] interval and is up to 2 digits after the decimal point. When you calculate the average, you can't count the illegal data.Input format:Enter the first line to give the positive integer n (Output format:For each illegal input, output "error:x is not a
