Jquery:1.jQueryobject is throughJQueryPackagingDOMObject that is generated after the object。jquery objects are unique to jquery. If an object is a jquery object, it can use the method in jquery: $ ("#test"). html ();For example: $ ("#test"). html () means: Gets The HTML inside the element with ID test Code. where html () is the method in jQueryThis code is equivalent to using the DOM Implementation code: document.getElementById ("test"). InnerHTML;Although jquery objects are created afte

Tips for C ++ Primer Chapter 4, primerchapterChapter 3 Requirements of operators with different left and right expressions on calculation objects and return value types Value assignment operator: A (non-constant) left value is required as its left operation object, and the result is still a left value. Take the address character: acts on a left value calculation object and returns a right value (it is a pointer to the left value calculation object )

],: scope operator (scope operator,: operator) 4. endl is a special value called an operator. When writing it into the output stream, it has a line feed effect and refreshes the buffer associated with the device. By refreshing the buffer, you can immediately see the output written to the stream. 5. Comment: A single line comment starts with a double slash (//). Multiple lines comment starts with "/*" and ends; 6. Some while statements, for statements, and if statements are not explained; 7. Read

, since functions with const or non-const parameters are no different in C.Miscellaniesint *v1; This should be understood from right to left, V1 is a reference, and a int* type binding. You can specify a default argument only once for one parameter. Each version of the overloaded function should be declared in the same scope. function pointers can only be initialized or assigned by a function or function pointer of the same type or by a 0-value constant. A direct referen

Getline (cin,string s) can read a whole line, including whitespace characters. End With CTRL + ZString literals are different types from string literals. Two string literals cannot be added directly.When working with characters in a string object, C + + defines a number of library functions that are easy to use.If you want to process each character, you can use the range for statement: for (declarationg:expression), if you want to change the value in expression, you can define declaration as a r

(i) extern in the header file usageBecause the header file is contained in more than one source file, and the definition of the variable can only occur once, in the header file, you can only declare that no definition can occur. We can declare global variables in the header file with extern, so that the declared global variable (such as variable A in the following program) can be used directly in the CPP containing this header file.But there are three exceptions:1. Class can be defined in the he

, delete the operation, size will change, record a constant will cause an iterator invalidation problem, in addition, do not have to worry about the efficiency problem, size is the inline function, the cost of each call is very small.(d) const_iteratorWe can use iterators to traverse the container, and we can dereference the iterator to change the value of the element in the container (*iter = 5). But what if we don't want to change the value of the element? This explains Const_iterator.When we

Example 3-1 turn on the lightTitle: There are n lamps, numbered 1~n. The 1th man turned all the lights on, and the 2nd man pressed the switches of all multiples numbered 2 (the lights would be turned off), and the 3rd man pressed the switch with multiples of 3 (where the lights were turned on, the lights turned off), and so on. A total of k people, ask the last of those lights open? Input: N and K, the output light number of the open. kAnalysis: Using sign[1],sign[2],..., Sign[n] Indicates wheth

arithmetic sort (beg,end,comp) used for ordering the elements ;the algorithm that checks for the specified value is used by default == operator. The system provides an additional named (rather than overloaded) version number for this type of algorithm: Find (beg,end,val); Find_if (beg,end,pred);an algorithm with a predicate function, with the name of a _if suffix. Of the find_if algorithm is used to find an element that causes the predicate function pred to return a value other than 0.

Bitset types are easier to use than lower-level bit operations on integer values, simplifying the processing of bit sets. When defining Bitset, specify the number of bits that Bitset contains and give its length value within the angle brackets.Note the number of bit sets starts at 0 and the lower level is low.One of the most important questions: Bitset's subscript is starting from the right!!!! A lot of people's blogs have been written wrong, hoping to attract people's attention.1. Initialize th

objects with pointersIf the pointer points to an object (which needs to be a valid pointer), you can use the dereference * to access the object. It can be assigned to operations such as a value.Null pointerA null pointer does not point to any object, and the code can first check whether it is empty before attempting to use a pointer. methods for generating null pointers: int *p1 = nullptr; // 等价于int *p1 = 0; C++11 new standard, recommended use int *p2 = 0; /
