Const in C language has always been a pain point for beginners in C language. This is because const has different functions in different locations and has different roles in different scenarios. This leaves beginners confused. Today, I will study

Sorting algorithms can be divided into internal and external sorting, the internal sorting is the data records in memory to sort, and the external sort is because of the data is very large, one can not hold all the sort records, in order to access

Learn C language, must be around the pointer this big difficulty, and the pointer is the most headache is a variety of pointing relations, first-order pointers are relatively easy to grasp, but once the order of a high, it is easy to understand the

Defined:A structure body (struct) is a collection of data consisting of a series of data of the same type or different type, also called a structure. The form of declaring a struct type is: Copy Code code as follows: struct student{//

Scope and storage type of variablesI. Scope and lifetimeThere are three types of identifier scopes for C programs: local, Global, and file. The scope of an identifier determines which statements in the program can use it, in other words, the

First, static1. Constructor:Characteristics:1, the function name and the class name are the same.2. You do not have to define a return value type (and void is not the same thing, and a constructor does not have to define a return value type at all).3

The Java Interface concept:It's about the narrow interface type. The generalized interface refers to the interface of the class and the interface of the method.Initial understanding, can be considered a special abstract classWhen a method in an

In Java, to implement a certain time to invoke a piece of code is very simple thing, that is, the use of interfaces.In C + +, there is a more advanced way, that is, the use of function pointers. For example, Cocos2d-x timers (schedule), message
