After you create an object with a constructor, the program keeps track of the object until it expires. After the object expires, the program calls the destructor to complete the cleanup of the object.Several features of the destructor:1. There can be only one destructor, and if there is no explicit definition, the compiler will automatically generate a default destructor;2. Destructors cannot be overloaded;When the destructor is called:1. If you create a static storage class object, the destruct

What is an array?An array is an unordered sequence of elements, and all elements in an array have the same type.Declaring an array variable:Int[] A; the size of the array is not part of the Declaration;To create an instance of an array:A=new Int[3];Initialize the array variable:Int[] A=new int[2]{1,2};Int[] a={1,2};Time[] schedule={new time, New Time (5,30)};To create an implicitly-typed array:var name=new[]{new {name= "John", age=44},new {name= "Diana", age=45}};To iterate over an array:You can

Every time you create an object, he will execute it.2. Construction code is faster than constructor execution.3. The difference between building blocks and constructors is that building blocks of code is a unified initialization of all objects, and constructors are initialized to the corre

This paper introduces the basic of GIS algorithm, coordinate transformation algorithm, data transformation and organization algorithm, space measure algorithm, index algorithm, interpolation algorithm and so on, which basically covers some fundamental GIS algorithms that we use daily. Of course, it would be better to pick up our calculus and linear algebra again before

Suppose that an integer is stored in one byte (8 bits), and if A is an unsigned integer variable, then when the a=64 is shifted to the left one when the overflow is 0, and the left 2 bits, the overflow high position contains 1.6. Right shift operator (>>)The right-shift operator is used to move the bits of a number to the right of a number of bits, the number of bits moved is specified by the right operand (the right operand must be non-negative ), the low end of the right side is di
