法學使用HTML和CSS構建技術文件網站
學習如何使用HTML和CSS設計技術文件網站。網站佈局專注於最佳化程式設計文件領域的內容組織，以提供使用者友好的導航。
為了實現非技術的外觀和感覺，HTML用於內容佈局，CSS用於構建和呈現此使用者友好的文件。
設計響應式技術文件網站的關鍵步驟
實現方法包含幾個關鍵點，這些關鍵點有助於網頁的整體設計和功能：
- HTML結構 − HTML文件的結構及其劃分為各個部分使用語義HTML元素；例如<header>、<nav>、<main>、<section>等。
- 導航欄 − 左側始終存在垂直導航欄，必須標記為#navbar，這對於瀏覽文件非常有用，可以帶來更好的體驗。學習：如何建立響應式導航欄。
- 響應式設計 − 為了使網頁可在不同裝置上訪問，原始碼中將使用響應式設計。
- 使用CSS進行樣式設定 − 主體背景、字型型別、顏色和文件中使用的空格是CSS檔案構成精美外觀的一些方面。
- 程式碼高亮 − 程式碼片段插入到帶樣式的<code>標籤中，增強了內容理解，併為文件中的示例提供了特殊的樣式。
- 列表組織 − 新概念也使用專案符號<ul>和<li>編寫，以使使用者能夠輕鬆識別關鍵點。
- 配色方案 − 使用配色方案可在文字及其背景之間實現良好的對比度，以便於閱讀且賞心悅目。
- 懸停效果 − 將效果應用於導航欄中包含的連結，以使選單具有互動性，並在使用者瀏覽選單時顯示效果。
- 輔助功能考慮 − 在HTML中使用正確的標籤和結構，以便螢幕閱讀器能夠儘可能輕鬆地瀏覽內容。
- 程式碼註釋 − 程式碼中包含註釋，以便後來的開發者能夠理解構建程式的不同元件時使用的概念。

<header>What is C++?</header>
<p>C++ is a general purpose programming
language and widely used now a days '
for competitive programming. It has
imperative, object-oriented and generic
programming features. C++ runs on lots of
platform like Windows, Linux, Unix, Mac etc.
C++ is an efficient and powerful language and finds wide use
in various GUI platforms, 3D graphics and
real-time simulations. Because of the
inclusion of rich function libraries,
working in C++ becomes simpler and
convenient than C. Being object-oriented
programming like Java, C++ provides
the support of inheritance, polymorphism,
encapsulation, etc. Unlike C, C++ allows
exception handling and function overloading..</p>
<p>The “Hello World” program is the first step towards learning any programming language...</p>
<code>
#include<iostream> <br>
using namespace std; <br>
int main() <br>
{ <br>
cout << "Hello World"; <br>
return 0; <br>
}
</code>
<p>C++ is an Object-Oriented Programming Language. The main pillars of Object-Oriented Programming are:</p>
<ul>
<li>Objects and Classes</li>
<li>Inheritance</li>
<li>Polymorphism</li>
<li>Abstraction</li>
<li>Encapsulation</li>
</ul>
</section>
<section class="main-section" id="Object">
<header>Objects and Classes</header>
<p> Object-oriented programming – As the name
suggests uses objects in programming.
Object-oriented programming aims to
implement real-world entities like
inheritance, hiding, polymorphism,
etc in programming. The main
aim of OOP is to bind together the data
and the functions that operate on them
so that no other part of the code can
access this data except that function.</p>
<p><b>Object : </b>An Object is an identifiable
entity with some characteristics and behavior.
An Object is an instance of a Class. When a
class is defined, no memory is allocated but
when it is instantiated (i.e. an
object is created) memory is allocated.
<br>
<b>Class : </b>The building block of C++ that
leads to Object-Oriented programming is a Class.
It is a user-defined data type, which holds its
own data members and member functions, which can
be accessed & used by creating an instance
of that class. A class is like a blueprint for
an object. For Example: Consider the Class
of Cars. There may be many cars with different
names and brand but all of them will share
some common properties like all of them will
have 4 wheels, Speed Limit, Mileage range etc.
So here, Car is the class and wheels,
speed limits, mileage are their properties.</p>
</section>
<section class="main-section" id="Inheritance">
<header>Inheritance</header>
<p>The capability of a class to derive
properties and characteristics from
another class is called Inheritance.
Inheritance is one of the most important
feature of Object Oriented Programming.
Sub Class: The class that inherits
properties from another class
is called Sub class or Derived Class.
Super Class: The class whose properties
are inherited by sub class is called Base
Class or Super class. Using inheritance, we
have to write the functions only one time
instead of three times as we
have inherited rest of the three classes
from base class(Vehicle).</p>
<p><b>Mode of Inheritance : </b><br><br>
<b>Public Mode : </b>If we derive a sub
class from a public base class. Then the
public member of the base class will
become public in the derived class and
protected members of the base class
will become protected in derived class.
<br><br>
<b>Protected Mode : </b>If we derive a
sub class from a Protected base class.
Then both public member and protected
members of the base class will become
protected in derived class.
<br><br>
<b>Private Mode : </b>If we derive a
sub class from a Private base class.
Then both public member and protected
members of the base class will become
Private in derived class.
<br><br>
<b>Types of Inheritance in C++ : </b>
<br><br><br>
<b>Single Inheritance :</b> In single
inheritance, a class is allowed to inherit
from only one class. i.e. one sub class
is inherited by one base class only.
<br><br>
<b>Multiple Inheritance :</b> Multiple
Inheritance is a feature of C++ where a
class can inherit from more than one
classes. i.e one sub class is inherited
from more than one base classes.
<br><br>
<b>Multilevel Inheritance :</b> In this
type of inheritance, a derived class is
created from another derived class.
<br><br>
<b>Hieratical Inheritance :</b> In this
type of inheritance, more than one sub
class is inherited from a single base
class i.e. more than one derived class
is created from a single base class.
<br><br>
<b>Hybrid (Virtual) Inheritance :</b>
Hybrid Inheritance is implemented by
combining more than one type of
inheritance.
For example: Combining Hierarchical
inheritance and Multiple Inheritance.</p>
</section>
<section class="main-section" id="Polymorphism">
<header>Polymorphism</header>
<p>The word polymorphism means having many
forms. In simple words, we can define
polymorphism as the ability of a message
to be displayed in more than one form.
A real-life example of polymorphism, a
person at the same time can have
different characteristics.
Like a man at the same time is a father,
a husband, an employee. So the same
person posses different behavior in
different situations. This is called
polymorphism. Polymorphism is considered
as one of the important features of Object
Oriented Programming.
<br>
<b>In C++ polymorphism is mainly
divided into two types:</b>
<br> 1. Compile time Polymorphism<br>
2. Runtime Polymorphism</p>
<p>Compile time polymorphism: This type of
polymorphism is achieved by function
overloading or operator overloading.
<br> Runtime polymorphism: This type
of polymorphism is achieved by
Function Overriding.</p>
</section>
<section class="main-section" id="Abstraction">
<header>Abstraction</header>
<p>Data abstraction is one of the most
essential and important feature of object
oriented programming in C++. Abstraction
means displaying only essential information
and hiding the details. Data abstraction
refers to providing only essential information
about the data to the outside world,
hiding the background details or implementation.
<br> Consider a real life example of a man driving
a car. The man only knows that pressing the
accelerators will increase the speed of car
or applying brakes will stop the car but he
does not know about how on pressing accelerator
the speed is actually increasing, he does
not know about the inner mechanism of the car
or the implementation of accelerator, brakes
etc in the car. This is what abstraction is.</p>
<p><b>Abstraction using Classes:</b> We can
implement Abstraction in C++ using classes.
Class helps us to group data members and member
functions using available access specifiers. A
Class can decide which data member will be
visible to outside
world and which is not.
<br>
<b>Abstraction in Header files:</b> One
more type of abstraction in C++ can be
header files. For example, consider the
pow() method present in math.h header file.
Whenever we need to calculate power of a
number, we simply call the
function pow() present in the math.h header
file and pass the numbers as arguments
without knowing the underlying algorithm
according to which the function is actually
calculating power of numbers.
<br><br><b>Advantages of Data Abstraction:</b><br>
1. Helps the user to avoid writing
the low level code.<br> 2. Avoids code
duplication and increases reusability.<br>
3. Can change internal implementation of
class independently without
affecting the user.<br> 4. Helps to
increase security of an application or program
as only important details are
provided to the user.</p>
</section>
<section class="main-section" id="Encapsulation">
<header>Encapsulation</header>
<p>In normal terms Encapsulation is defined
as wrapping up of data and information
under a single unit. In Object Oriented
Programming, Encapsulation is defined as
binding together the data and the functions
that manipulates them. Consider
a real life example
of encapsulation, in a company there are
different sections like the accounts section,
finance section, sales section etc. The finance
section handles all the financial transactions
and keep records of all the data related to
finance.
Similarly the sales section handles all the
sales related activities and keep records of
all the sales. Now there may arise a situation
when for some reason an official from finance
section needs all the data about sales in a
particular
month. In this case, he is not allowed to
directly access the data of sales section.
He will first have to contact some other
officer in the sales section and then
request him to
give the particular data. This is what
encapsulation is. Here the data of
sales section and the
employees that can manipulate them are
wrapped under a single name “sales section”.</p>
<p>Encapsulation also lead to data abstraction
or hiding. As using encapsulation also hides
the data. In the above example the data of
any of the section like sales, finance or
accounts is hidden from any other section.<br>
In C++ encapsulation
can be implemented using Class
and access modifiers.</p>
