烟花代码（包教包会）_randint, uniform,choice下载

新的一年就要来了，想放放烟花？但专家说放烟花会污染环境，这不，网上有安全无污染的烟花，这是用C写的代码烟花，有声音有配乐，还很好看

想要代码的去百度网盘自取

运行环境：   Visual Studio 2022       EasyX 

我已经加EasyX环境到文件里了，  点击 Fire\x64\Debug\Fire.exe 这个文件看看能运行吗？

不能运行就下载Visual Studio 2022配置环境

看下面

 

下载 Visual Studio 2022 这个在编程界有一定地位的IDE，懒得写了，看别人的文章

(10条消息) Visual Studio 2022 IDE 下载安装与环境配置，C语言/C++集成环境配置，VS2022。详细环境配置教程，最适合写c语言的编译器_立志冲海大的博客-CSDN博客_c语言vs工作负载选哪个https://blog.csdn.net/lwj8819/article/details/122384631

下载后配置EasyX环境

easyx下载

EasyX Graphics Library for C++EasyX Graphics Library 是针对 Visual C++ 的绘图库，支持 VC6.0 ~ VC2019，简单易用，学习成本极低，应用领域广泛。目前已有许多大学将 EasyX 应用在教学当中。https://easyx.cn/
进入EasyX的官网，按照如下步骤安装EasyX：

点击下载，下载最新版本。在电脑上下载的如下版本：
 

 

 下载成功后直接双击即可进行安装，此安装路径默认为VS2022中的安装路径。

 环境配置完，安装完重启一下Visual Studio2022就可以使用了

在Visual Studio新建一个C++项目

 

 然后把刚才网盘下载的代码文件中的下面5个素材文件复制到新建的test项目中

 

在Visual Studio，源文件——添加——现有项

 选择test项目下的Fire.cpp

 好了，可以点击运行了

 效果很惊艳是吧？

换另一个表白烟花的代码试试
