是以，在這裡我們將從頭開始。

We will start with the basics and build up to the fundamentals of this C plus plus programming language with the intention to make you a good C plus plus programmer.

我們將從基礎知識開始，逐步提高這種 C plus 編程語言的基礎知識，目的是讓你成為一名優秀的 C plus 程序員。

So, in this lecture, we are going to just see the basic introduction to C plus plus.

是以，在本講座中，我們將看到 C plus plus 的基本介紹。

We will see what is this C plus plus language, who designed it, when was it designed, and we will see the key features of this language, and we will see what are the main things that we are going to cover in this course.

我們將瞭解什麼是 C plus plus 語言，它是由誰設計的，什麼時候設計的，我們還將瞭解這種語言的主要特點，以及我們將在本課程中涉及的主要內容。

So, once again, welcome to this course, where we are going to learn about this wonderful language C plus plus.

是以，再次歡迎來到本課程，我們將在這裡學習 C plus plus 這門奇妙的語言。

So, coming to the introduction to C plus plus, C plus plus is a general purpose programming language.

是以，在介紹 C plus plus 時，C plus plus 是一種通用編程語言。

Now, what do we mean by general purpose programming language?

So, general purpose programming language means, it is a language that can be used for general purpose.

是以，通用編程語言意味著它是一種可用於通用目的的語言。

That means, it can be used for writing softwares in different domains.

這意味著，它可用於編寫不同領域的軟件。

It can be used for writing softwares for different applications and different domains.

它可用於編寫不同應用和不同領域的軟件。

So, that is why we call it a general purpose programming language.

是以，我們稱它為通用編程語言。

Now, C plus plus was designed and implemented by the Danish computer scientist Bjarne Struestrup in 1979 at the Bell Labs.

現在，C plus plus 是由丹麥計算機科學家 Bjarne Struestrup 於 1979 年在貝爾實驗室設計和實現的。

So, this is the amazing person who have designed and implemented the C plus plus programming language.

這就是設計和實現 C plus plus 編程語言的神奇人物。

So, you may have some idea about the C programming language.

是以，您可能對 C 編程語言有一些瞭解。

You must have heard at least about the C programming language.

你一定至少聽說過 C 編程語言。

Now, C plus plus is actually an extension of the C programming language with more features and is more powerful than the C programming language.

現在，C plus plus 實際上是 C 編程語言的擴展，具有更多的功能，比 C 編程語言更強大。

So, we will see the differences between C and C plus plus, and we will see the more powerful features that are there in the C plus plus programming language as we move ahead in this course.

是以，我們將看到 C 和 C plus plus 之間的區別，並將在本課程中看到 C plus plus 編程語言更強大的功能。

Now, C plus plus runs on a variety of platforms such as Windows, Mac OS, and the various versions of Unix.

現在，C plus plus 可以在各種平臺上運行，如 Windows、Mac OS 和各種版本的 Unix。

So, we see that C plus plus is supported on most of the major platforms that we have like Windows, Mac, and Unix.

是以，我們可以看到，C plus plus 支持 Windows、Mac 和 Unix 等大多數主要平臺。

So, we can use it for a wide variety of applications for writing different softwares that can be used in different domains.

是以，我們可以將其廣泛應用於編寫可用於不同領域的不同軟件。

Now, this is just the basic introduction to C plus plus.

現在，這只是 C plus plus 的基本介紹。

So, we see that it is a general purpose programming language, and we see who is a scientist who designed and implemented it.

是以，我們看到它是一種通用編程語言，我們也看到了設計和實現它的科學家是誰。

Now, before we move ahead, here is a fun fact for you.

現在，在我們繼續之前，先給大家講一個有趣的事實。

The initial version of C plus plus was called C with classes.

C plus plus 的最初版本被稱為 C with classes。

So, as I already said, C plus plus is an extension of C.

是以，正如我已經說過的，C plus plus 是 C 的擴展。

So, we first had the C language, and C plus plus was designed to have more features as compared to C.

是以，我們首先有了 C 語言，與 C 語言相比，C plus plus 的設計具有更多功能。

Now, one of the major features that is there in C plus plus and not in C is the concept of classes.

現在，C plus plus 中有而 C plus 中沒有的一個主要功能就是類的概念。

Now, because of that, before the term C plus plus was coined, the name given to C plus plus was actually C with classes.

是以，在 "C plus plus "這個詞出現之前，"C plus plus "實際上被稱為 "C with classes"。

So, that was the first name that was given, and later on they decided to call it C plus plus.

所以，這就是最初的名字，後來他們決定叫它 C plus plus。

So, that is about the basic introduction to C plus plus along with a small fun fact for you.

以上就是關於 C plus plus 的基本介紹，還有一個小趣聞。

So, as I just said, C plus plus is an extension of C.

是以，正如我剛才所說，C plus plus 是 C 的擴展。

So, let us talk a little more about that.

那麼，讓我們再談談這個問題。

So, talking about C plus plus as an extension of C, C plus plus is actually a better C.

是以，說到 C plus plus 作為 C 的擴展，C plus plus 實際上是一種更好的 C。

So, as I already said, C plus plus has more features and is more powerful as compared to C.

是以，正如我已經說過的，與 C 語言相比，C plus plus 擁有更多的功能和更強大的性能。

So, we can say that it is a better C, and it supports data abstraction, it supports object oriented programming, and it supports generic programming.

是以，我們可以說它是更好的 C 語言，它支持數據抽象，支持面向對象編程，支持泛型編程。

So, if you are a person who is new to programming, then these terms may sound new to you and you may not understand it at the moment.

是以，如果你是一個編程新手，那麼這些術語對你來說可能聽起來很陌生，你可能一時無法理解。

So, don't worry about it, we are going to make everything clear as we move ahead in this course.

所以，不用擔心，我們會在本課程中把一切都講清楚。

So, for now, we are not going to explain or go into the details of these terms, but just know that C plus plus supports all these features that we have listed here.

是以，現在我們不打算解釋或深入探討這些術語的細節，只想知道 C plus plus 支持我們在這裡列出的所有這些功能。

So, that is why we say that it is a better C, and it is more powerful as compared to the C programming language.

是以，我們說它是更好的 C 語言，與 C 編程語言相比功能更強大。

So, now let us take an example from the C language.

So, here I am taking a small example from the C language.

是以，我在這裡舉一個 C 語言的小例子。

So, some of you may already know the C language, and even if you don't know, no problem at all.

是以，有些人可能已經知道 C 語言，即使不知道，也完全沒有問題。

So, in this example, let I be an integer variable whose value is equal to six.

是以，在這個例子中，假設 I 是一個整數變量，其值等於 6。

Now, again, if you are new to programming, you may not understand the meaning of this term variable, and what do we mean by I is an integer and all that.

再說一遍，如果你是編程新手，你可能不理解變量這個術語的含義，也不知道 I 是整數是什麼意思。

For now, just understand that we are having a variable.

現在，我們只需明白，我們有一個變量。

Variable is something that can hold a value.

變量是指可以保持數值的東西。

So, just think of variable as something that can hold a value.

是以，只要把變量看作是可以保存數值的東西就可以了。

Now, I is a variable which is an integer.

Now, integer means the same kind of integer that we have in mathematics.

現在，"整數 "指的就是數學中的整數。

So, I is a variable that can hold an integer value.

是以，I 是一個可以保存整數值的變量。

Now, I plus plus will increment the value by one.

現在，I plus plus 將使數值遞增 1。

Now, this plus plus, if you put this plus symbol two times after this I, that signifies an increment operator in C.

現在，這個加號加號，如果在 I 後面加上兩個加號，就表示 C 語言中的增量運算符。

The increment operator will increase the value by one.

So, I plus plus is an increment operator, and it will increase the value and make I is equal to seven because the previous value of I was equal to six.

是以，I plus plus 是一個遞增運算符，它會增加數值，使 I 等於 7，因為 I 之前的數值等於 6。

So, that is what the increment operator or this plus plus operator does.

這就是增量運算符或這個加加運算符的作用。

現在，我們為什麼要討論這個問題？

We are discussing this because I want to emphasize the fact that the term C plus plus was coined because of this particular reason.

我們之所以討論這個問題，是因為我想強調，C plus plus 這個詞就是因為這個特殊原因而產生的。

So, we saw that plus plus is an increment operator, and because of that C plus plus was chosen to denote it being the next or the successor or increment of the C programming language.

是以，我們看到 plus plus 是一個遞增運算符，正因為如此，C 加 plus 才被用來表示它是 C 編程語言的下一個運算符、繼承運算符或遞增運算符。

So, we said that C plus plus is an extension of C, and the name C plus plus was chosen in order to denote that it is the next or the successor or an increment of the C programming language.

是以，我們說 C plus plus 是 C 語言的擴展，選擇 C plus plus 這個名稱是為了表示它是 C 編程語言的下一代、繼承者或增量。

So, that is why I wanted to discuss this small example to tell you why this plus plus is there after this C, making it C plus plus.

是以，我想通過這個小例子來告訴大家，為什麼這個 C 後面會有一個加號，使它成為 C 加加號。

So, now let's discuss the prerequisites that we need to know before learning the C plus plus programming language.

現在，讓我們來討論一下在學習 C plus plus 編程語言之前需要了解的先決條件。

So, coming to the prerequisites, let us ask ourselves some few questions.

那麼，說到前提條件，讓我們問自己幾個問題。

Do I need to have prior knowledge of C to learn C plus plus?

學習 C plus plus 是否需要具備 C 語言知識？

So, in the previous slide, we have just seen that C plus plus is actually an extension of C.

是以，在上一張幻燈片中，我們看到 C plus plus 實際上是 C 的擴展。

So, do you need to have any prior knowledge of C in order to learn C plus plus?

那麼，學習 C plus plus 是否需要任何 C 語言方面的知識呢？

The answer is no, you don't need to know C to learn C plus plus.

答案是否定的，學習 C plus plus 不需要懂 C 語言。

So, if you already know C, that is well and good, but even if you don't know it, it is totally fine because C plus plus in itself is a complete programming language, and we are going to start from scratch and discuss everything right from the basics.

是以，如果你已經會 C 語言，那很好，但即使你不會，也完全沒關係，因為 C 加加本身就是一門完整的編程語言，我們將從零開始，從基礎開始討論一切。

So, you don't need to have any prior knowledge of C in order to learn C plus plus.

是以，學習 C plus plus 不需要任何 C 語言知識。

And then, do I need to know any other programming languages before learning C plus plus?

那麼，在學習 C plus plus 之前，我還需要掌握其他編程語言嗎？

So, apart from C, is there any other programming languages that you need to know before learning C plus plus?

那麼，除了 C 語言，在學習 C plus plus 之前，還需要掌握其他編程語言嗎？

You don't need to know any other programming languages before learning C plus plus.

在學習 C plus plus 之前，您無需掌握任何其他編程語言。

So, if you have chosen C plus plus as your first programming language, it is totally fine because we are going to learn everything as I said from scratch.

是以，如果你選擇 C plus plus 作為你的第一門編程語言，完全沒有問題，因為我們將從頭開始學習我所說的一切。

So, we will start from the basics and cover each and everything that is required in order to learn this language.

是以，我們將從基礎開始，涵蓋學習這門語言所需的一切。

So again, if this is your first programming language, you have made a good choice in choosing this as your first programming language.

是以，如果這是你的第一門編程語言，那麼選擇它作為你的第一門編程語言也是一個不錯的選擇。

So, we see that basically there are no prerequisites in order to learn C plus plus.

是以，我們可以看到，學習 C plus plus 基本上不需要任何先決條件。

You can just learn it from whatever position that you are right now.

你可以從你現在所處的任何位置開始學習。

現在，讓我們來看看教學大綱。

So, coming to the syllabus, we will see what are the main things that we are going to discuss in this course.

是以，在教學大綱中，我們將討論本課程的主要內容。

So, here are the list of the basic topics that we are going to discuss in this course.

以下是我們將在本課程中討論的基本主題。
