C, a statically typed procedural programming language famous for making the world go round.

It's the language behind many tools we take for granted, like the Windows, Linux, and Mac operating system kernels, databases like MySQL, interpreters for languages like

Python, tools like Vim and Git, and countless others.

It was created in 1972 by Dennis Ritchie at Bell Labs, where it would be used to develop the Unix operating system.

It would go on to become the mother of all languages, inspiring the syntax of C++, C Sharp, Java, JavaScript, Perl,

and PHP, just to name a few.

It compiles directly to machine code and requires minimal runtime support,

but is platform -dependent, meaning the executable is designed to run on a specific operating system.

It's a high -level language designed for humans, yet provides low -level control over memory and hardware.

There's no garbage collector.

Instead, your code needs to manage its own memory.

When you create a variable, it's assigned an address in memory.

You can store that address in another variable called a pointer.

When the variable is no longer needed, you'll need to free it to avoid memory leaks.

To get started, install a C compiler.

A popular choice is the GNU C compiler, or GCC.

Create a file ending in .c, include any libraries you plan to use, then add a main function to it.

This is where your program will start executing.

There's no function keyword, and notice how it returns an integer type.

A return value of 0 means success, while a return value of 1 means failure.

There are only a few basic types in C.

Create a variable by starting with a type, followed by a name and value.

Use printf to print the value to the standard output, or put an ampersand in front of it to reference its address in memory.

There's no string type, but instead char, which represents a 1 -byte character stored as an integer.

A string can be created with an array of characters.

Each letter will have its own memory address and be terminated by a null character.

Another approach is to start with a pointer by adding a star character in front of the type, then we can allocate 4 bytes to it.

Now assign a character to each index, ending with the null character to create a string.

When you no longer need that memory allocated to your program, use free to release it back to the computer's RAM.

The language is procedural and does not support object -oriented features, although you can create your own complex data types using structs.

Now compile your code to machine instructions for your operating system using the C compiler.

This has been the C programming language in 100 seconds.

本课的词汇与口语要点

这节口语课以视频“C in 100 Seconds”为素材。视频中反复出现的词有：memory, language, character, type, create。这段视频共有 34 个句子、487 个单词可供跟读。讲话部分时长为 2:25。说话人语速较快，每分钟约 202 个词，会出现较多连读和弱读。只有 77% 的单词属于英语最常用的 3,000 词，词汇难度较高。

视频中的重点词汇

视频中 15 个值得学习的单词，附发音和释义：

单词	发音	释义
string 名词	/stɹɪŋ/	線 /线
null 名词	/nʌl/	空值
assign 动词	/əˈsaɪn/	分配, 分派
pointer 名词	/ˈpɔɪn.təɹ/	教鞭
output 名词	/ˈaʊtpʊt/	輸出 /输出
database 名词	/ˈdeɪtəˌbeɪs/	數據庫 /数据库
hardware 名词	/ˈhɑɹdˌwɛɹ/	硬件, 硬體 /硬体

需要注意的发音

长单词——注意重音位置: procedural /pɹəˈsiːd͡ʒ(ə)ɹəl/, interpreter /ɪnˈtɝ.pɹɪ.tɚ/, executable /ˈɛksəkjutəbl/

中文母语者容易读错的音：

词尾辅音 — 要读清楚，后面不要加元音: output /ˈaʊtpʊt/, database /ˈdeɪtəˌbeɪs/, dependent /dɪˈpɛndənt/, garbage /ˈɡɑɹ.bɪd͡ʒ/, leak /liːk/
/r/ 和 /l/ 的区别: variable [ˈvæɹ.i.ə.bl̩], procedural /pɹəˈsiːd͡ʒ(ə)ɹəl/
/æ/ — 嘴张大，不要读成 /e/: variable [ˈvæɹ.i.ə.bl̩], syntax /ˈsɪn.tæks/, allocate /ˈæl.ə.keɪt/, ampersand /ˈæm.pə(ɹ).sænd/

如何用这段视频练习

先完整听一遍视频，不要开口，记下不认识的单词。
先用 0.75 倍速逐句跟读，熟练之后再回到正常速度。
录下自己的声音并与原声对比，特别注意 string, null, assign 这类单词。

什么是跟读法？

跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
