1
C, a statically typed procedural programming language famous for making the world go round.
2
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
3
Python, tools like Vim and Git, and countless others.
4
It was created in 1972 by Dennis Ritchie at Bell Labs, where it would be used to develop the Unix operating system.
5
It would go on to become the mother of all languages, inspiring the syntax of C++, C Sharp, Java, JavaScript, Perl,
6
and PHP, just to name a few.
7
It compiles directly to machine code and requires minimal runtime support,
8
but is platform -dependent, meaning the executable is designed to run on a specific operating system.
9
It's a high -level language designed for humans, yet provides low -level control over memory and hardware.
10
There's no garbage collector.
11
Instead, your code needs to manage its own memory.
12
When you create a variable, it's assigned an address in memory.
13
You can store that address in another variable called a pointer.
14
When the variable is no longer needed, you'll need to free it to avoid memory leaks.
15
To get started, install a C compiler.
16
A popular choice is the GNU C compiler, or GCC.
17
Create a file ending in .c, include any libraries you plan to use, then add a main function to it.
18
This is where your program will start executing.
19
There's no function keyword, and notice how it returns an integer type.
20
A return value of 0 means success, while a return value of 1 means failure.
21
There are only a few basic types in C.
22
Create a variable by starting with a type, followed by a name and value.
23
Use printf to print the value to the standard output, or put an ampersand in front of it to reference its address in memory.
24
There's no string type, but instead char, which represents a 1 -byte character stored as an integer.
25
A string can be created with an array of characters.
26
Each letter will have its own memory address and be terminated by a null character.
27
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.
28
Now assign a character to each index, ending with the null character to create a string.
29
When you no longer need that memory allocated to your program, use free to release it back to the computer's RAM.
30
The language is procedural and does not support object -oriented features, although you can create your own complex data types using structs.
31
Now compile your code to machine instructions for your operating system using the C compiler.
32
This has been the C programming language in 100 seconds.

المفردات وملاحظات التحدث لهذا الدرس

هذا الدرس في المحادثة مبني على الفيديو “C in 100 Seconds”. أكثر الكلمات تكرارًا في الفيديو: memory, language, character, type, create. يحتوي هذا الفيديو على 34 جملة و487 كلمة للتدرب على الترديد. مدة الكلام 2:25. يتكلم المتحدث بسرعة، نحو 202 كلمة في الدقيقة، لذا ستسمع كثيرًا من وصل الكلمات واختزال الأصوات. 77% فقط من الكلمات ضمن أكثر 3,000 كلمة شيوعًا في الإنجليزية، فالمفردات صعبة نسبيًا.

أهم المفردات في هذا الفيديو

15 كلمة من الفيديو تستحق التعلّم، مع النطق والمعنى:

الكلمةالنطقالمعنى
string اسم/stɹɪŋ/وَتَر
assign فعل/əˈsaɪn/تعيين شخص لعمل ما
output اسم/ˈaʊtpʊt/مُخرَج
database اسم/ˈdeɪtəˌbeɪs/قَاعِدَة بَيَانَات
hardware اسم/ˈhɑɹdˌwɛɹ/مَتاع الحاسب, المَتاع
dependent صفة/dɪˈpɛndənt/مُتَوَقِّفْ, مُعْتَمِدْ
garbage اسم/ˈɡɑɹ.bɪd͡ʒ/زُبَالَة, نُفَايَات
install فعل/ɪnˈstɔl/رَكَّبَ
instruction اسم/ɪnˈstɹʌkʃən/تَعْلِيم
leak اسم/liːk/تَسَرُّب
subscribe فعل/səbˈskɹaɪb/اِشْتَرَكَ
execute فعل/ˈɛksɪˌkjuːt/أَعْدَمَ
syntax اسم/ˈsɪn.tæks/بِنَاء جُمْلَة, نَحْو
allocate فعل/ˈæl.ə.keɪt/خَصَّصَ
byte اسم/baɪt/بَايْت

نطق يحتاج إلى انتباه

  • الكلمات الطويلة — انتبه لموضع النبر: procedural /pɹəˈsiːd͡ʒ(ə)ɹəl/, interpreter /ɪnˈtɝ.pɹɪ.tɚ/, executable /ˈɛksəkjutəbl/

أصوات يجدها متحدثو العربية صعبة:

  • /p/ — ليس /b/: انطقه مع نفخة هواء: pointer /ˈpɔɪn.təɹ/, procedural /pɹəˈsiːd͡ʒ(ə)ɹəl/, output /ˈaʊtpʊt/, dependent /dɪˈpɛndənt/, inspire /ɪnˈspaɪə(ɹ)/
  • تتابع الصوامت — لا تضف حركة بينها: string /stɹɪŋ/, procedural /pɹəˈsiːd͡ʒ(ə)ɹəl/, hardware /ˈhɑɹdˌwɛɹ/, dependent /dɪˈpɛndənt/, install /ɪnˈstɔl/

كيف تتدرب بهذا الفيديو

  1. استمع إلى الفيديو كاملًا مرة واحدة دون أن تتكلم، ودوّن الكلمات التي لا تعرفها.
  2. ابدأ بسرعة 0.75×، وردّد جملة جملة، ثم عُد إلى السرعة العادية عندما يصبح الأمر سهلًا.
  3. سجّل صوتك وقارنه بالأصل، مع الانتباه إلى كلمات مثل string, assign, output.

ما هي تقنية التظليل الصوتي؟

التظليل الصوتي (Shadowing) تقنية تعلم لغة مدعومة علمياً، طُورت أصلاً لتدريب المترجمين الفوريين المحترفين. الطريقة بسيطة لكنها قوية: تستمع لصوت إنجليزي أصلي وتكرره فوراً بصوت عالٍ — كظل يتبع المتحدث بتأخير 1-2 ثانية. تُظهر الأبحاث تحسناً كبيراً في دقة النطق والتنغيم والإيقاع وربط الأصوات والاستماع والطلاقة.
