0. PrefaceFrom the beginning of learning C language began to contact Makefile, consulted a lot of makefile information but always feel no real master makefile, if you write a makefile always feel very laborious. So deliberately using the blog to summarize the relevant knowledge of makefile, through examples to illustrate the specific use of makefile. The example says that makefile roughly divides into 4 parts 1. Only a single C file 2. Contains multiple C files 3. Need to include header file pa

? macro definition: In a program, the start of a # is a preprocessing instruction.#define定义宏常量can appear anywhere in the code. As shown in the following illustration:To determine whether the macro definition is correct, to take the content of the macro definition to the real program, according to the actual program. #define从本行开始, this macro constant is availabl

1. Define the interfaceUse interface to define an interface.Interface definition similar to the definition of the same, is also divided into the interface of the Declaration and interface body, which consists of a constant definition and method definition two parts. The basic format for defining an interface is as foll

How to Use macro definition in C LanguageExplanation of macro replacement in C LanguageFirst, let's look at the following question:# Include # Define PRINT_CLINE () printf ("% d ",______) Int main (void) { PRINT_CLINE (); PRINT_CLINE (); Return 0; } Fill in the appropriate code at the horizontal line so that the output of the above Code is 34. I think most people do not have a clear idea to answer this question when they s

The examples in this article describe the definition, inheritance, and methods of using objects in Python. Share to everyone for your reference. The specific analysis is as follows: The concept of a class in Python programming can be likened to a description of a collection of types, such as "human", which can be regarded as a class and then defined by the human class as the object of every specific person-you, me, him, etc. Classes also have propert

When using VS to develop a u3d project, look at the declaration of a variable, such as the gameobject variable of a component, and see the following codeA look seems a bit dizzy, this code what meaning ah, just a public gameobject gameobject {get;}This is a bit like a concise declaration of attributes:But is that the truth? Tested, not soWrite a small program to verify that you know.First write a DLL program, and then write a test program to reference the DLL, in the test program to use go to

Stored procedures can be reused to reduce the workload of database developers.(2) improve performance. The stored procedure is compiled when it is created. You do not nee

In the process of beginner JS, it is always impossible to distinguish what is function expression and what is function definition, which is detrimental to the compaction of basic knowledge. Therefore, the access to information, carefully distinguish it.A brief summary is as follows:1. Difference One: function is defined by functions, and others are function expressions;2. Difference two: The function expression can omit the function name. func

1. Use interface to define an interface. An interface defines a class-like definition that consists of an interface's declaration and interface body, where the interface body consists of a constant definition and a method definition. The basic format for defining an interface is as follows:1 interface Interface Name [extends parent interface List]{2 [public] [st

This article mainly introduces the definition, inheritance, and usage objects of classes in Python. it analyzes the related concepts and usage skills of classes in Python in detail and has some reference value, for more information about class definition, inheritance, and object usage in Python, see the examples in this article. Share it with you for your reference. The specific analysis is as follows: The

1. The knowledge points learned in this lesson:(1) This class of learning array, a most basic type of construction, it is a set of the same type of data ordered collection.(2) The elements in the array are kept in memory, each element belongs to the same data type, and the array elements can be uniquely determined with array names and subscripts.(3) Definition and reference of a one-dimensional array: Defines an array that requires explicit array vari

above introduction is a first-level pointer, the next introduction is the definition and use of level two pointers. What is a level two pointer? A secondary pointer is the address used to hold the pointer variable!The definition of a first-level pointer:Data type * pointer variable nameint *p; (P is the pointer variable name, type int)Char *ch; (ch is the pointer variable name, type char)The
