This article mainly introduces the implementation of C language in detail -- the example code in project 2048 is introduced in great detail, which has certain reference value. Interested partners can refer to it!

Introduction to the game:

2048 is a puzzle game. The rules of the game are very simple. It is a simple and easy-to-use digital game. The rules of the game are very simple. You need to control all the squares to move in the same direction. After two identical digital squares collide together, they are merged into their sum. After each operation, a 2 or 4 will be randomly generated. Finally, you will win if you get a "2048" square!

Simple and easy to play! Therefore, it has also become a very good small project for our programming learners' C language practice. If you haven't played it, you can play it first. If you can play it, it is also very helpful for the understanding of project logic! Next, let's have a look!

Plug in: the graphics library plug-in easyX, which involves picture materials, can be found by Baidu or collected at the end of the text;

For the unfinished digital part of the code, you can also think about it first. Every thinking is the process of your progress!

If you have any problems in the process of learning and what you don't understand about this project, you can come to me for communication and I'll help you!

So that's all for today's sharing. More wonderful projects or knowledge content will be updated in the future. We should learn C language c + +~

Write at the end: for those who are ready to learn C/C + + programming, if you want to better improve your core programming ability (internal skill), you might as well start now!
