However, the game is a rather complex product, logic and logic, logic and data sometimes forced decoupling does not make development easy, and sometimes it will increase the amount of work (such as the development of a relatively simple project

Void * memory = operator new (sizeof (string); // gets the original memory, used to place a string object
Call string: string ("memory management") on * memory; // initializes an object in the memory.
String * ps = static_cast
Note that step 2 calls a constructor. As a programmer, the new operator does not have the right to use constructor like this, but the compiler does.
This is why new operator must be used if you want to create a heap-based

There are three main forms of new in C ++: new operator, operator new, placement new
The usage of the three is different. Pay attention to the differences:
New OPERATOR:
The new operator, like other operators in the C ++ language (such as +,-,->,:...), is built in the language and always accomplish the same thing,ProgramMembers cannot change their meaning. The following is a new usage:
String* PS =New String("Hazirguo");

Generally, people want to use their favorite apps on all their devices, regardless of the device's targeting. In iOS8 and later versions, you can use the size class and automatic layout to define the screen layout when the device placement environment changes, how should the View Controller and view be adjusted to help you meet th
work of the new operator to pass the unprocessed pointer returned by operator new to an object. When your compiler encounters such a statement:
String * PS = new string ("Memory Management ");
The code generated by it is more or less similar to the following code (for more details, see article 8 and article 10 of Objective C ++, as well as comments in my article counting object .) :
Void * Memory = // get unprocessed memoryOperator new (sizeof (string); // String objectC
(){ if(rawMemory = null) return ; if(size != sizeof(Base)) { ::operator delete(rawMemory); return ; } // 归还内存等操作}Author summary
Operator new should contain an infinite loop in which to attempt to allocate memory, and if it does not meet the memory requirements, it should call New-handler. It should also be able to handle 0bytes applications. The class-specific version of Ze should also handle "larger (error) applications than the correct size".

Turn from: JAVA notes callable and Futuretask: Multithreading with return valuesThe commonly used thread class has no return value after the Run method executes, and a third-party dump is required to implement the return value to the main thread after the child thread completes the task. The callable interface provides a multithreaded implementation method with return values. Here is a simple landlord, Overwatch Hachang example to show the use of this

class, and the memory that may be requested when the subclass is called is not the size you want, usually it is small, and when overridden in a base class, the sizeof operator can provide some help to avoid making mistakes, But be careful. If the base class also overwrites operator new[], then be more careful to make sure that the memory size requested by the subclass is not wrong. 6) operator Delete, it is good to ensure that a null pointer is removed without error. But also make sure that th

I. INTRODUCTIONThere are three ways to use NEW: plain New,nothrow new and placement new.(1) Plain new, as the name suggests, is the ordinary new, is our usual use of new. This is defined in C + +:void* operator New (std::size_t) throw (Std::bad_alloc);void operator delete (void *) throw ();Tip:Plain New throws an exception std::bad_alloc instead of returning null in the event of an allocation failure, so it is futile to judge whether the return value
the constructor on the object. The othertypelist here as the parameter list is compatible with the type of the argument list expression-list in the new parenthesis (that is, the formal parameter argument can match).
New operator with position, semantically including four use cases:
Directly gives the memory location of the object to be constructed;Does not throw an exception if the memory allocation fails to return an empty pointer;Custom, with other parameters of the memory allocator;For deb

There is a difference between saving data as text and a URL. If you save the data in text format, the data does not receive any special processing. If you save the data as a URL, the browser treats it as a link in the Web page. In other words, if you put it in another browser window, the browser will open the URL.
