Recently, I have been engaged in terminal hacking, involving the ANSI control code. I have searched the internet and learned a lot. If you telnet to a Linux server, then enter the command, such as VI test. c. Then the client can see test. file C. If you capture packets, you can see that the packet contains more than test. C content, there are some seemingly garbled things. For example:
Int num, FD;/033 [22; 9 hchar M [6000];/033 [23; 9 hchar R [6000]

Your computer terminals and terminal emulators support color and cursor control through a system of escape sequences. One such standard is commonly referred to as ANSI colour. Several terminal specifications areBased on the ANSI color standard, including vt100.
The following is a partial listing of the VT100 control set.
Represents the ASCII "escape" character, 0x1b. Bracketed tags represent modifiable deci

Char * pchar = string (_ file __);
Printf ("% S % s \ n", pchar, _ file __);
We can compare the differences between string (_ file _) and _ file _. The front will contain double quotation marks, and the last one will not contain double quotation marks.
Next, let's talk about the # function. It can be spliced with a token-pasting operator ).
There is an example on msdn:
# Define Paster (n) printf ("token" # N "= % d \ n", Token # N)
Int token9= 100;

As long as there are standard DES encryption and decryption algorithms, similar to the ANSI-X99MAC algorithm and pboc3des algorithm is very good implementation. They are all using DES algorithm and then through a layer of algorithm implementation. The principle of implementation to see the picture can be understood. The implementation of the 3DES algorithm is much simpler. Is the DES algorithm and decryption once more./********************************

It is similar in shell programming.
If you use a colored prompt to increase personalization, you need to use escape sequences. The escape sequence is a control command that allows shell to execute a special step. Generally, escape sequences start with ESC (which is also the reason for its naming ). In shell, it is re

Recently, I reorganized the code and upgraded cocos2dx from 3.0 to 3.2. Record the problems during the upgrade.
The reason why I only upgraded to 3.2 is that later versions use lua5.2, while I still prefer 5.1 and can continue to use luajit. Another reason is that cocosstudio, versions later than
Ansi c and object-oriented programming
Do you think that to program in an object-oriented style you need an object-oriented language? Well, you're wrong. it seems to be a common myth that you need an object-oriented language to implement an object-oriented design and, although versions ages such as C ++ and Java provide extends features that encourage this style of design, you can benefit equally well from the use of objects in imperative versions ag
