1.用C语言编写一个简单的源码书管理小程序
2.急求C语言编写的图书管理系统源代码，具体要求如下
3.MacBook(m1)源码编译opencv
4.图书馆借阅系统源代码
5.如何查看iebook软件源代？

用C语言编写一个简单的源码书管理小程序
源代码如下：#include<iostream>
#include<iomanip>
#include<string>
#include<fstream>
#include<stdio.h>
using namespace std;
const int maxb=; //最多的图书
class book//图书类
{
int tag; //删除标记1:已删0:未删
int number; //isbn书号
char name[]; //书名
char author[]; //主编
char number2[];//版次
char position[];//出版社
char time[];//出版年
void addbook(int n,char *na,char *au,char *n2,char *da,char *ti,int pr) //增加图书
{
tag=0;
number=n;
price=pr;
strcpy(name,na);
strcpy(author,au);
strcpy(number2,n2);
strcpy(position,da);
strcpy(time,ti);
onshelf=1;
}
扩展资料
1、源程序中，源码很多符号都是源码成对匹配出现的，为避免遗漏必须配对使用的源码符号。
2、源码接龙群源码用花括号括起来的源码部分，但从程序结构清晰，源码便于阅读、源码理解、源码维护的源码角度出发，建议在书写程序时应遵循以下规则，源码以养成良好的源码编程习惯。
3、源码一个说明或一条语句占一行，源码与该结构开始处的左花括号对齐。

首先，从GitHub上获取OpenCV的源代码是实现MacBook (m1)本地编译的关键步骤。你可以通过运行以下命令来拉取最新版本:
bash
git clone /opencvopencv.git
如果你想锁定特定的版本，比如2.1分支，可以使用如下命令替换`[tag_name]`为实际的版本号:
bash
git clone --branch [tag_name] /opencvopencv.git
接下来，为了进行编译，你需要准备一个专门的构建目录，这可以通过以下命令创建:
bash
mkdir opencv_build
cd opencv_build
然后，运行CMake来配置编译环境:
bash
cmake ..
配置完成后，开始编译安装过程:
bash
make
sudo make install
整个过程涉及到了从GitHub获取源代码、创建编译目录、配置CMake并执行编译和安装。最后，务必确认你的目录结构包括了源代码、构建目录以及安装后的文件。

如何查看iebook软件源代？
查看IEBook软件源代码的过程，主要取决于你是否具有编程知识以及你所指的源代码具体是哪一部分。如果只是想查看软件的配置或设置文件，通常这些信息在软件安装路径的某个目录下可以找到。例如，你可以检查“C:\Program Files\IEBook\config.ini”之类的路径，查看包含软件设置信息的配置文件。
至于查看源代码本身，这可能需要你了解一些编程语言，如C++或Java，因为这些是IEBook软件的常见开发语言。首先，你需要下载并解压IEBook的源代码。通常，开发者会将源代码打包在一个.zip或.tar.gz文件中。解压后，你可以在解压目录下找到并阅读源代码文件。
不过，请注意，并非所有软件都公开其源代码。IEBook开发者如果选择不公开源代码，你就无法查看其源代码。此外，即使源代码公开，你可能需要具备相关的编程知识和技能才能理解代码逻辑。
如果你的目标是学习如何使用IEBook软件，那么查看源代码可能不是最佳途径。相反，你可以通过查找教程、视频或官方文档来学习如何使用软件。这些资源通常能更直接地帮助你理解软件的使用方法和功能。
总之，查看IEBook软件的源代码可能涉及编程知识，以及对软件的内部结构有一定程度的了解。如果你只是想学习如何使用该软件，可能更应该关注使用教程和官方文档。如果你是开发人员并且有权限查看源代码，那么上述步骤将帮助你找到并阅读源代码。
kafka源码阅读之MacBook Pro M1搭建Kafka2.7版本源码运行环境
在探索Kafka源码的过程中，决定搭建本地环境进行实际运行，以辅助理解和注释。由于日常开发中常使用Kafka 2.7版本，选择了在MacBook Pro M1笔记本上搭建此版本的源码环境。搭建过程中，记录了遇到的障碍，方便未来再次搭建时不必从头开始。 搭建Kafka 2.7源码环境需要准备以下基础环境：一、Zulu JDK1.8
在MacBook Pro M1笔记本上，基本都已安装JDK，版本不同而已。使用的是Zulu JDK1.8版本，通过下载.dmg格式的一键安装，环境自动配置，安装路径通常在 /Library/Java/JavaVirtualMachines。二、Scala 2..1
并未在系统里安装Scala，而是直接利用IDEA。按照Preferences -> Plugins -> Scala安装。选择IDEA的不同Scala JDK版本。三、安装Gradle6.6
通过官网gradle.org/releases/下载Gradle6.6版本。如国内下载速度较慢，可直接从百度网盘下载安装包。安装完成后，解压并放置在目录/Users/helloword/software/gradle-6.6，通过mac终端执行指令配置环境。四、Zookeeper3.4.6安装
直接从百度网盘下载zookeeper-3.4.6.tar.gz包，解压后放置在三台机器的/app目录下。在每个目录中创建data子目录，并建立myid文件，按照特定数字填写。在zoo.cfg文件中进行配置并复制至其他机器。五、Kafka2.7源码部署
从官网下载Kafka 2.7源码，或从百度网盘获取。解压至目录/Users/helloword/software/kafka/kafka-2.7.0-src，并通过Gradle构建环境。在mac终端执行指令，生成gradle-wrapper.jar，配置依赖。将源码导入IDEA，加载Gradle构建的项目。六、源码运行
确保源码运行打印日志，需将log4j.properties复制到core的 resources目录，并在build.gradle中添加log4配置。修改config/server.properties配置，包括zookeeper路径和broker的ip。配置server、consumer、producer三个进程，确保Kafka服务、消费者和生产者能够正常工作。 整个Kafka 2.7版本源码的本地搭建步骤完成。后续计划撰写系列文章总结阅读源码的经验。关注公众号写代码的朱季谦，获取更多分类归纳的博客。
