In this paper, we describe the method of implementing subclass calling Parent class in C #, and share it for everyone's reference. Here's how:I. Creating a subclass instance from a subclass-free constructor functionCreate the parent class person and subclass student.public class person{Public person () { Con

object.What do you call dynamic creation?is the ability to dynamically create an object of that class based on the name of a class.For example, your program needs to use a text file, and this file contains some class names, can you dynamically generate these classes according to these names?/*****************************************************************************//* The name of the

One, C + + polymorphicThe polymorphism of C + + includes static polymorphism and dynamic polymorphism. Static polymorphism includes function overloading and generic programming, and dynamic polymorphism includes virtual functions. Static polymorphism means that during compilation, dynamic polymorphism is defined only when the program is running.Second, virtual function1, the virtual function is a non-static

determine the number of elements in the array, so there is no need to count each.sizeof is an operator and is used similar to a function. When the parameter is an array name, the number of bytes of memory is given to the entire array, and when the argument is a type, the number of bytes of that type variable is obtained.For string arrays, initialization has a more convenient method:Char name[] = "Always Laugh";The name is then automatically assigned to an array of length 13 (Don't forget the '

C ++ abstract class overview, abstract classI. Reasons for the article The virtual method and virtual class can be said to be a major feature of the c ++ language, and some people may even say it is the essence of the c ++ language. In fact, this is also true, because the Ru

The following describes the main attributes and methods of a program instance.

Download the code in this article:Zipcompression.exe(150kb) Summary When you store files or send files over the network, using zip compression can save space and network bandwidth. In addition, the directory structure of the ZIP folder will not be lost, which makes it a very useful compression solution.

In this paper, a method is given. The basic idea is to write a wrapper file, encapsulate the C + + class, and only provide the C language interface, and C++I related are implemented in the wrapper implementation file.1. apple.h[CPP]View Plaincopyprint? #ifndef __apple_h__ #define __apple_h__

A static member function does not have the this pointer, and it cannot return non-static members because the class itself can be invoked in addition to the object calling it.Static member functions can directly access the static data and function members of the

If it weren't for Apple, it wasn't app Store,object-c. I'm afraid it's already out of sight. Most programming languages are based on the C grammar style, so the first touch of this non-C-style language, will not understand its strange grammar. But if it is mastered, it will not feel too much different. Keep a record of its bottom-up operations today.1: Classes cl
