C++实践：班级随机点名软件
文章摘要
|
好久没更新了，今天有点能写的就来写一下吧~
起因：曹老师让我们在班上的电脑上搞一个随机点名，我们几个都对这个比较兴奋（有正经的理由能中午在班里玩电脑了），胡、李、余觉得应该用班级优化大师，于是我们下了班级优化大师，然后发现居然要登录，而我们手机都交了（啊啊啊气死我了）
于是我提议用C++写一个……于是就有了下文
程序运行截图：
让我们来实现这个代码吧：

| 分析维度 | 版本 0.0.1 (第一个代码段) | 版本 0.0.2 (第二个代码段) | 主要升级点分析 |
|---|---|---|---|
| 架构与设计 | 面向过程。功能集中在一个主文件，通过全局变量和函数实现。 | 面向对象。引入了 RollCallApp、NameListManager、Utils 等类，职责分离清晰。 |
提升了代码的模块化、可维护性和可扩展性。新架构更易于理解和后续开发。 |
| 核心功能 | 单一列表随机抽取。从一个名单文件读取所有名字。 | 分类与批量抽取。 1. 性别分类：从 n.txt（男）和 s.txt（女）分别读取名单。2. 范围选择：可指定抽取"全部"、“男生"或"女生”。 3. 批量抽取：输入数字可一次性抽取多人。 |
功能显著增强。支持按性别筛选和批量操作，实用性更强。 |
| 文件处理 | 复杂路径与编码处理。 - 尝试从"Program Files"和"我的文档"读取。 - 内置 UTF-8 到 GBK 的编码转换。 |
路径简化，编码隐式处理。 - 固定从 D:\2502sjdm\ 读取。- 依赖系统控制台编码，无显式转换。 |
去除了复杂的编码转换逻辑，降低了出错风险，但牺牲了路径灵活性。 |
| 代码质量与特性 | 基础功能。包含随机、保存、彩蛋、调试信息。 | 优化与增强。 - 动画效果：抽取时有名字快速切换的动画。 - 常量与配置：用常量定义路径、颜色等。 - 错误处理：有更明确的错误提示（如"403 目录不存在"）。 - 用户界面：提示信息更友好，如显示人数统计。 |
用户体验和代码健壮性得到优化。动画和更好的提示提升了交互体验。 |

| 变更类别 | 变更位置 | v0.0.2 版本 | v0.0.3 版本 | 升级点分析 |
|---|---|---|---|---|
| 版本标识 | 常量 APP_VERSION |
“v0.0.2” | “v0.0.3” | 更新了软件版本号。 |
| 常量类型优化 | 常量 NAME_MAX_LENGTH |
const int NAME_MAX_LENGTH = 8; |
const size_t NAME_MAX_LENGTH = 8; |
将与字符串长度相关的常量类型改为 size_t，与标准库函数（如string::length()）返回值类型保持一致，提高了类型安全性和代码一致性。 |
| 函数参数匹配 | Utils::centerAlign 方法参数 |
int width |
size_t width |
配合上述常量类型的修改，消除了潜在的隐式类型转换警告。 |
| 显式类型转换 | RollCallApp::playSelectionAnimation 方法 |
setw(NAME_MAX_LENGTH) |
setw(static_cast<int>(NAME_MAX_LENGTH)) |
setw 期望 int 类型参数。将 size_t 类型的常量显式转换为 int，避免了编译器的类型不匹配警告。 |
| 显式类型转换 | RollCallApp::randomSelectSingle 方法 |
dis(0, names.size() - 1) |
dis(0, static_cast<int>(names.size()) - 1) |
uniform_int_distribution<> 默认使用 int 类型。将 size_t 显式转换为 int，同样是为了消除编译器警告，确保随机数生成的类型安全。 |
| 功能移除 | RollCallApp::handleCommand 方法 |
包含对 "egg" 或 "easter" 命令的处理分支。 |
已删除 彩蛋命令的处理分支。 | 移除了彩蛋功能。 |
这个时候是老师用到的的一个版本，说要给他们班上的电脑也搞一个
