In C language programming, for a relatively large project, the use of the library will be more, if the design of a slight negligence, it may create a macro-defined conflict. An example of a project is that the two header file defines "isspace (CH)", and the two macro definitions are inconsistent, causing the entire project to fail to compile. The solution to this problem is to undefine the

A day ago, I finally finished the second pass of the design pattern. In these two times, I learned a lot of knowledge. Before looking at OoTV design competition, always mentioned the principle of object-oriented design, which makes me unclear so, until after reading the whole book, only to know that the book has its own gold house. This article mainly writes about the six principles of object-oriented desig

Yes, I'm currently going to write a book about unity shader.The purpose of the book is to have the following several: Summarize my experience with unity Shader and give others a reference. I am very aware of the difficulties of learning shader, and I have seen many questions raised by people in the group. I think learning shader is still a

What needs to be stated are:1. Query the platform of the book is a watercress reading2. The Chinese name of the book is embedded directly in the request link, because it

1. OverviewAfter the const keyword is found in C ++, the macro definition constant function is no longer recommended. This makes Dehong useless. In fact, macros can do a lot of things, and it is difficult for me to list them all. Here, we only list several typical usage examples, and hope you can benefit from them. 2. Multi-Environment compatibilityA common situation is that we implement a function and expect it to be compiled and used only when some

Macro Definition Learning (1) Macro names are generally capitalized(2) The use of macros can improve the universality and readability of the program, reduce inconsistencies, reduce input errors and facilitate modification. Example: array size common macro definitions(3) Preprocessing is the processing before compiling, and one of the tasks of compiling is g

Today, my colleague sent me an access file and opened it and jumped out of a form. I want to see some properties of this form. I didn't expect the file to be automatically closed after I pressed the design view button. # % $ *@! # ^ ?, Challenge me! Open the file again and clickToolsMenu>StartupIn general, the form started when the access file is opened is set here, but there is nothing in the main here. I originally wanted to cancel the form opening here. Let's take a look at the other one

Objective:In the work, many small partners will be in the PCH file definition some common macros, but also afraid to write these simple macro waste of time, and sometimes forget how to define what to do? I am also in the work of the same. So here to share some common macro definitions, like the small partners can be used directly in the project (continuous update)!For the convenience of everyone, please cli

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

In GNU C, a macro can accept a variable number of arguments, just like a function__va_args__ can be regarded as the ... Assign a value to the macro // Note you can't call ABC () #include #include #define ABC (...) printf (__va_args__) /* void ABC (...) {//printf (__va_args__);} */ int Main () {ABC ( " %s\n , " hello ); return 0 ;} Note that the m
