the string is a \ 0 character. Therefore, for Compiler, 'A' and "A" are different.8. When two strings are adjacent, compiler automatically connects the two strings and adds a \ 0 at the end. For example, "two" "some" will be expressed as twosome, but note that a string and a wide string cannot be connected, such as "two" L "some ", this is not acceptable. Section 2 variable1. variables are different from text constants and constants (variables modified with const). variables have two attributes

1, generally $name[' Tom ' and $name[tom] are the same; but the key without the quotation mark cannot be distinguished from the constant, such as: Define (' Index ', 5); $name [' Tom '] and $name[tom] are different 2, the variable in double quotes is generally used in {} is a good habit, such as: Echo "{$name}"; 3. Array $name = Array (' Tom ', ' Jim ', ' Alice '); and $username = [' Tom ', ' Jim ', ' Alice ']; 4, the array with the = symbol to specify an initial value, followed by the key v

If you buy a MacBook from Hong Kong, you will find that the charger is not plugged into the home outlet, so it is not convenient to retrofit the home outlet, so you need an adapter:2.

. Staticobj: Static objects, static non-animated objects are intended for animated objects. For example: surface, props. Usually do not change pictures. (Special needs special treatment) Moveableobj: The object that can be moved. Should include objects that can be moved subjectively and passively. Of course, you're willing to use a passive object (like the one that pushes the box) as a static object. NPC: Non-player control role. SPC: The player can control the character. In fact, it usually swi

Adapter Mode Core idea: The object of the A interface is transformed into an object of the B interface, so that it looks like a B object. But it is true that the A object is running the actual business logic.The first feeling of seeing the adapter pattern is this: Is this a pattern? That's how it should be handled!！！Life has a lot of live examples, such as network adapter (NIC), modem, data cable, charger and so on.The downside is. There needs to be such an extra talent for conversion.Advantages

Simple sha1 encryption function example implemented by PHP and phpsha1 encryption example This example describes the sha1 encryption function implemented by PHP. We will share this with you for your reference. The details are as follows: function encryptTokey($data){ $apikey = 'testapikey111'; $ps1 = sha1($apikey . strtolower($data)); $ps1 = strtoupper($ps1); $s1 = implode(str_split($ps1, 2), '-'); $ps2 = md5($s1 . $apikey); $

Virtual terminal is a kind of fake terminal, the terminal that really has its own monitor and keyboard, will connect to the computer host through special cable (such as serial port). VT100 is a virtual terminal specification supported by most Linux systems, and it is commonly used for ANSI,xterm and so on.Set the PATH variablewhen you enter a comm

network devices to process IPv6 packets, it also provides streaming support and higher security. Currently, IPV4 addresses are represented in dotted decimal notation. How can next-generation IPv6 addresses be expressed? Because the IPv6 address is 4 times longer than the IPv4 address, it is more complex to express than the IPV4 address. The basic expression of IPv6 network addresses is X: X, where X is a 4-bit hexadecimal INTEGER (1 6 digits ). Each number contains four digits, each integer con

ESP is located in the tss+4 location. Every time Windows switches threads, the RING0 esp in TSS is always set up.After the interrupt processing is completed, the EIP,CS,EFLAGS,ESP,SS is ejected from the kernel stack via Iret, and the control is given to the user-mode code pointed to by the EIP.Obviously, there are many processes involved in the mode switching process through int 2e/iret, which is expensive.

HTML5 adds many new semantic and functional tags. Although we can select them through document. getelementbyid and document. getelementsbytagname, a problem occurs when copying nodes. The innerhtml that should have appeared is a null string ...... Therefore, we need to treat them differently when copying them, which is a prerequisite for how to identify them.
