C以及C语言这俩编程界所谓的“老兄弟”直至如今依旧是无数开发者争论不休的要点所在究竟它们谁更具优势呢实际上去争论这个并没有什么实际意义弄清楚它们各自所擅长的方面、在何处分道扬镳才是你能够编写出优质程序的关键之处。C语言系统底层的基石C语言在1972年于贝尔实验室诞生是由Dennis Ritchie主导进行开发的。它在设计开始的时候就有着一个明确的目标那就是写操作系统。在1973年Unix系统被用C语言重新编写此事件直接奠定了C在系统编程领域的统治地位。直至今日Windows、Linux、macOS这些主流操作系统的内核绝大部分代码依旧是C语言。你每日使用的电脑、手机底层都在运行着由C语言编写的代码。C语言具备的最大优势是其贴近硬件它不存在复杂的运行时环境编译之后直接生成机器码程序员能够凭借指针直接对内存地址进行操作在嵌入式领域像你家用于电饭煲的控制芯片以及汽车发动机的控制单元这些资源有限的设备而言C语言差不多是唯一的选择其语法简单学习曲线相对较为平缓能让你清楚理解计算机底层究竟是如何开展工作的。C面向对象的进化1983年Bjarne Stroustrup于贝尔实验室推出C其首个想法纯粹即赋予C语言面向对象之能力只因伴随软件规模增大纯C语言之组织形式愈发难以维护C留存C之高效执行同时引入类、继承以及多态此类概念此“带着约束舞动”的方式令大型项目之代码编排变得清晰且可控。C可不是单纯的“C加加”这般简单它历经了好多回重大更新像C11、C14、C17、C20啦每次更新时都在引入那种现代编程范式现下的C支持泛型编程、函数式编程特性标准库给出了STL容器、智能指针、多线程支持同C语言比起来C能让你靠着更少的代码去达成更复杂的功能与此同时还维持着近乎C语言的运行效率。内存管理手动与半自动在C语言里其内存管理完全依靠malloc以及free来进行你得自行去计算所需的字节数量还要自己去检查分配是否成功使用完毕后必须要手动去释放。一旦要是忘记了释放那便出现了内存泄漏的情况要是已经释放了还继续去使用那就是悬空指针现象。这两个问题占据了C语言程序中bug的很大一部分。在大型工程项目里追踪内存泄漏属于极为耗时的一项工作。C将new与delete引入进来只是这属于语法糖范畴其本质并未发生改变。然而C给出了更为安全的解决办法那便是RAII资源获取即初始化以及智能指针。借助构造函数取得资源利用析构函数释放资源再结合shared_ptr与unique_ptr能够使对象生命周期实现自动管理。在C代码当中你绝对能够做到不书写一个delete从而彻底规避手动内存管理所带来的风险。标准库工具箱的差距C语言的标准库规模不大主要用以供给字符串操作、数学函数、输入输出等基础功能。比如说要是你打算实现一个动态数组又或者是一个哈希表在C语言环境下就得自行手写。这致使不同项目的基础代码重复进行类似工作并且质量差异较大。C语言的字符串处理函数strcpy、strcat自身就存在安全隐患需要开发者对缓冲区溢出格外留意。C的标准库强大程度远超其他STL给出了vector、map、unordered_map、string这般容器直接拿来用便可以算法库涵盖了排序、查找、遍历等常见操作文件流借由fstream予以处理字符串借助string类无需顾虑长度于实际开发之时C程序员少见需要自行去实现基础数据结构直接调用标准库既具备安全性又拥有高效性能够将精力聚焦于业务逻辑上面。应用领域各司其职嵌入式系统开发中C语言是王者。操作系统内核开发里C语言也是王者。因为这些场景对运行时环境要求严格不能有异常处理机制。不能有全 局构造器。内存必须精确控制。Linux内核代码规范禁止使用C。硬件驱动开发处C语言是首选。网络协议-stack使追求极致性能和控制的地方C语言是首选。在游戏引擎领域C是主流在大型桌面软件领域C是主流在高频交易系统等领域C是主流。虚幻引擎5的底层是用C写的因为它需要管理复杂的游戏对象继承体系因为它要保证每帧渲染的性能。办公软件像Microsoft Office核心代码是C浏览器像Chrome核心代码是C。这些项目规模动不动就几百万行代码面向对象的设计模式能使团队协作更顺畅。学习路径从C到C还是跳过C众多初学者在是否先研习C然后再去学习C这件事上备受纠结困扰。从语法层面而言C 事实上对绝大部分C代码予以兼容然而先去学习C或许会致使你养成某些不良的习惯。举例来说C语言习惯于运用指针加上长度去操控数组而C 则更倾向于推荐使用迭代器以及容器。先学习C会塑造出面向过程的思维定式当切换至面向对象时就需要再度去适应。更便捷的途径是径直去学习C 你能够先领会C里的面向过程部分也就是C语言的子集接着循序渐进地引入类、继承以及多态最终研习模板和STL 在这个学习进程当中着重明白C对照C的安全性以及抽象能力方面增进的部分并非刻意地去学C所拥有的那些不安全的用法像是裸指针的繁杂操作还有宏定义的过度运用这些在现代C状况下都存在更妥善的替代办法。在读罢这篇文章之后你可曾于项目当中因抉择C还是C而陷入过纠结纠结呢欢迎于评论区去分享你的亲身经历感受点滴详情点赞转发从而让更多的开发者得以看见知晓呢。node.smartnet168.comservice.smartnet168.com3wd.smartnet168.com6b.smartnet168.com1f7.smartnet168.comot.smartnet168.comn0.smartnet168.compromo.smartnet168.com5.smartnet168.comnpo.smartnet168.composts.smartnet168.comrum.smartnet168.com3v.smartnet168.com76l.smartnet168.comu9.smartnet168.com3eh.smartnet168.comz.smartnet168.com1u.smartnet168.comx0.smartnet168.com4m.smartnet168.comudr.smartnet168.com0i.smartnet168.com2hc.smartnet168.com5i.smartnet168.comvideo.smartnet168.comn38.smartnet168.com02h.smartnet168.compfg.smartnet168.comvs.smartnet168.com1n.smartnet168.com308.smartnet168.comru8.smartnet168.comyd0.smartnet168.com17.smartnet168.comnews.smartnet168.coms.smartnet168.comso.smartnet168.comyuy.smartnet168.comservices.smartnet168.comxy.smartnet168.com3.smartnet168.comnx9.smartnet168.comsy9.smartnet168.comlogin.smartnet168.comstatic.smartnet168.comupdate.smartnet168.com3rs.smartnet168.com4t5.smartnet168.comleg.smartnet168.comlx.smartnet168.comvwn.smartnet168.comnode1.smartnet168.comstatus.smartnet168.com75.smartnet168.com7.smartnet168.compost.smartnet168.com33f.smartnet168.com1i.smartnet168.comwmw.smartnet168.com3kd.smartnet168.comv5x.smartnet168.comsearch.smartnet168.com6pk.smartnet168.comw0.smartnet168.comuwc.smartnet168.comtv.smartnet168.comq2.smartnet168.comuw8.smartnet168.coms2w.smartnet168.comsafe.smartnet168.comnw3.smartnet168.com0y.smartnet168.comrank.smartnet168.comr.smartnet168.comun4.smartnet168.com6jl.smartnet168.comnz3.smartnet168.como1.smartnet168.comsales.smartnet168.com46.smartnet168.comseo.smartnet168.comsmartnet168.com81w.smartnet168.comuk0.smartnet168.com2c2.smartnet168.comwgx.smartnet168.comtoday.smartnet168.com16t.smartnet168.com1.smartnet168.comofficial.smartnet168.com3ej.smartnet168.comuu.smartnet168.comol.smartnet168.com7j6.smartnet168.comwyx.smartnet168.commh.smartnet168.comuc2.smartnet168.comuh2.smartnet168.comzo.smartnet168.com5x.smartnet168.comt3.smartnet168.comrq.smartnet168.comp7.smartnet168.comrc.smartnet168.coms8.smartnet168.comtags.smartnet168.com77d.smartnet168.comtest.smartnet168.com6i.smartnet168.com55.smartnet168.comsdw.smartnet168.comst6.smartnet168.com36.smartnet168.com70.smartnet168.com7b.smartnet168.comozf.smartnet168.comx87.smartnet168.comlc.smartnet168.commp.smartnet168.comqw.smartnet168.comyr.smartnet168.comtopic.smartnet168.comymx.smartnet168.comsg.smartnet168.com25.smartnet168.comstore.smartnet168.comyjs.smartnet168.com2bz.smartnet168.com3u.smartnet168.comvp.smartnet168.comzg0.smartnet168.comy2.smartnet168.com016.smartnet168.comzcm.smartnet168.comr0d.smartnet168.comx6b.smartnet168.comxs6.smartnet168.com3q.smartnet168.com2eo.smartnet168.comw60.smartnet168.comyud.smartnet168.commarket.smartnet168.compic.smartnet168.comnew.smartnet168.compay.smartnet168.comvip.smartnet168.comsk.smartnet168.comopen.smartnet168.comoffer.smartnet168.com3p.smartnet168.comq.smartnet168.comnq.smartnet168.com07.smartnet168.comp3.smartnet168.comzb.smartnet168.com7n.smartnet168.comrft.smartnet168.com6xu.smartnet168.comttc.smartnet168.com4uv.smartnet168.com33.smartnet168.comqqj.smartnet168.comw.smartnet168.comn1e.smartnet168.comno.smartnet168.com54t.smartnet168.comspeed.smartnet168.comnm.smartnet168.comsystem.smartnet168.comxd.smartnet168.commt.smartnet168.compme.smartnet168.comp.smartnet168.comtag.smartnet168.com4fl.smartnet168.com4zk.smartnet168.comx64.smartnet168.com66.smartnet168.comus.smartnet168.com4c.smartnet168.com58p.smartnet168.comu.smartnet168.comro.smartnet168.comrkl.smartnet168.comur.smartnet168.com0p5.smartnet168.comz2t.smartnet168.comty.smartnet168.comv.smartnet168.com49.smartnet168.comtjr.smartnet168.comy7.smartnet168.commks.smartnet168.com82v.smartnet168.comwz4.smartnet168.com67b.smartnet168.com6w.smartnet168.comwww.smartnet168.com2pv.smartnet168.comwww.smartnet168.com6.smartnet168.comlive.smartnet168.comljr.smartnet168.com67w.smartnet168.comud.smartnet168.compop.smartnet168.com7q.smartnet168.comwbh.smartnet168.comt.smartnet168.com70x.smartnet168.comrrc.smartnet168.comv4u.smartnet168.com4.smartnet168.com0.smartnet168.com7fq.smartnet168.comwj.smartnet168.coms28.smartnet168.comlinks.smartnet168.comyra.smartnet168.comp6o.smartnet168.com5e.smartnet168.comwap.smartnet168.comlh.smartnet168.comsupport.smartnet168.comttl.smartnet168.como9j.smartnet168.comn9.smartnet168.com6z.smartnet168.com68t.smartnet168.comqr2.smartnet168.comup4.smartnet168.com4et.smartnet168.com4x.smartnet168.comtopics.smartnet168.comlbh.smartnet168.comtdv.smartnet168.comumh.smartnet168.comwap.smartnet168.comxni.smartnet168.comq1.smartnet168.comtop.smartnet168.com513.smartnet168.comuser.smartnet168.com0d.smartnet168.comsmartnet168.coml26.smartnet168.com86.smartnet168.com84.smartnet168.commg.smartnet168.comtk0.smartnet168.commnj.smartnet168.comn4b.smartnet168.com3ld.smartnet168.comma.smartnet168.comnode2.smartnet168.coml2x.smartnet168.com7w.smartnet168.
