static bracelet

in general, if there are N homogeneous objects, each object has its own data member, and the data members of different objects have their own values, which are irrelevant to each other. But sometimes people want to have one or several data members that are common to all objects, which enables data sharing.You can use global variables to achieve the purpose of sharing data. For example, in a program file has multiple functions, each function can change the value of global variables, the value of

Preface:The member variables between objects and objects are independent of each other. To share data, you need to use static members and static methods. As long as you declare static member variables in a class, you can allocate space for static member variables, even if you do not define them, and you can use

However, based on my experience of statically comp

-bit machine each read is 64 bits, Equivalent to the length of 2 int can be read each time, each time you read a piece of data, the adjacent data may be read in, and the stack occupies a small space, so that the CPU hit rate will be higher, and the elimination rates will be lower, and the heap occupies a large space, relative to each read hit ratio is lower, The elimination rate is also higher, so from this point of view, the stack is faster than the heap to write.Above is the storage speed diff

See on the Internet, feel good, own notes down, later forget the convenient to see: A non-static method is relative to a static method. static methods use the static keyword to indicate that a non-static method does not have this keyword.The biggest difference between them

A brief analysis of the usage difference between static and non-static methods in PHP In PHP programming, the Static keyword declares that a property or method is related to a class and not to a particular instance of a class, so that such a property or method is also known as a class property or class method If the access Control permission allows, you do not h

① static members belong to the class, and non-static members belong to instances of the class. ② every instance of creating a class, the city in memory for the non static (dynamic) State members of the new allocation of a piece of storage; Static members are owned by the class and are common to instances of each class

Static Static and non-static problems should be found on the Internet to find some information, the following is the collation of some information. The existence of a non-static member depends on the instance, so it can also be called an instance member. The members in the class include: Data members:Data members ca
