|  C++ এ Abstract Class এবং Pure Virtual Function এর টিউটোরিয়ালে আপনাদের স্বাগত।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 00:08 &lt;br /&gt;
| এই টিউটোরিয়ালে আমরা শিখব,&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 00:10&lt;br /&gt;
| '''Abstract Classes'''&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 00:11&lt;br /&gt;
| '''Pure virtual function'''&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 00:13&lt;br /&gt;
| আমরা এটি একটি উদাহরণ দ্বারা করব।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 00:16  &lt;br /&gt;
|  টিউটোরিয়ালটি রেকর্ড করতে&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 00:19&lt;br /&gt;
| উবুন্টু OS সংস্করণ 11.10&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 00:23&lt;br /&gt;
| g++ কম্পাইলার সংস্করণ 4.6.1 ব্যবহার করছি।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
|  00:27&lt;br /&gt;
|  এখন Abstract Class এর ভূমিকা দিয়ে শুরু করি।&lt;br /&gt;
|-&lt;br /&gt;
| 00:31&lt;br /&gt;
| Abstract Class সর্বদা একটি '''base''' ক্লাস।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 00:35&lt;br /&gt;
|এতে অন্তত একটি Pure Virtual Function থাকে।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 00:39&lt;br /&gt;
|আমরা Abstract Class এর ইনস্ট্যান্স তৈরী করতে পারি না।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
|  00:43&lt;br /&gt;
| এখন Pure Virtual Function দেখি।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 00:45&lt;br /&gt;
|একটি Pure Virtual Function, বডি ছাড়া একটি ফাংশন।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 00:49&lt;br /&gt;
|এটি বেস ক্লাসে সংজ্ঞায়িত হয়নি।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 00:52&lt;br /&gt;
|এটি নিম্নরূপে ঘোষিত হয়েছে:&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 00:54&lt;br /&gt;
|'''virtual void virtualfunname()=0;'''&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 01:00&lt;br /&gt;
|একটি ডিরাইভ ক্লাসের ফাংশন ওভাররাইড করা আবশ্যক।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 01:04&lt;br /&gt;
|অন্যথায় কম্পাইলার একটি এরর দেবে।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 01:07&lt;br /&gt;
|ফাংশন বাস্তবায়ন করতে এটি ডিরাইভ ক্লাসের উপর নির্ভর।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 01:11&lt;br /&gt;
|  এখন একটি উদাহরণ দেখি।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 01:13&lt;br /&gt;
|আমি ইতিমধ্যে এডিটরে কোড লিখেছি।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 01:16&lt;br /&gt;
|আমি এটি খুলবো।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 01:18&lt;br /&gt;
|উল্লেখ্য যে আমাদের ফাইলের নাম abstract ডট cpp&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 01:22&lt;br /&gt;
|এই উদাহরণে দুটি সংখ্যার যোগফল এবং বিয়োগফল জড়িত থাকে।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 01:28&lt;br /&gt;
|  এখন কোড দেখি।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 01:30&lt;br /&gt;
|  iostream হিসেবে এটি আমাদের হেডার ফাইল।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 01:33&lt;br /&gt;
|  এখানে আমরা std namespace ব্যবহার করছি।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 01:36&lt;br /&gt;
|  এটি ক্লাসের জন্য ঘোষনাকরণ যা হল abstractinterface&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 01:41&lt;br /&gt;
|  তারপর আমাদের কাছে public স্পেসিফায়ার রয়েছে।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 01:44&lt;br /&gt;
|  এখানে আমরা একটি ভার্চুয়াল ফাংশন ঘোষিত করেছি যা হল &amp;quot;numbers&amp;quot;.&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 01:49&lt;br /&gt;
|এটি 0 তে ইনিসিয়েলাইজ করা হয়েছে।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 01:51&lt;br /&gt;
| তারপর আমাদের কাছে একটি নন-ভার্চুয়াল ফাংশন রয়েছে&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 01:55&lt;br /&gt;
|এবং a ও b হিসাবে দুটি ইন্টিজার ভ্যারিয়েবল রয়েছে।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 01:59&lt;br /&gt;
| এখানে আমরা input ফাংশন অ্যাক্সেস করি।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 02:01&lt;br /&gt;
|এতে আমরা সংখ্যা a এবং b গ্রহণ করি।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
|  02:05&lt;br /&gt;
| এটি একটি ডিরাইভড ক্লাস যা হল add.&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 02:09&lt;br /&gt;
|এটি বেস ক্লাস &amp;quot;abstractinterface&amp;quot; এর বৈশিষ্ট্য আহরণ করে।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 02:14&lt;br /&gt;
|  এখানে আমরা &amp;quot;numbers&amp;quot; ফাংশন ওভাররাইড করি।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 02:18&lt;br /&gt;
|এতে আমরা দুটি সংখ্যা a এবং b এর যোগফল সম্পাদন করি&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 02:21&lt;br /&gt;
|এবং ফলাফল ইন্টিজার ভ্যারিয়েবল &amp;quot;sum&amp;quot; এ  সংরক্ষণ করি।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 02:25&lt;br /&gt;
|তারপর ফলাফল প্রিন্ট করি।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 02:27&lt;br /&gt;
| এখানে sub নাম আরেকটি ডিরাইভড  ক্লাস রয়েছে।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 02:31&lt;br /&gt;
|এটিও বেস ক্লাস &amp;quot;abstractinterface&amp;quot; আহরণ করে।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
|  02:35&lt;br /&gt;
| এখানে, আবার আমরা &amp;quot;numbers&amp;quot; ফাংশন ওভাররাইড করি&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 02:39&lt;br /&gt;
|এবং এখানে আমরা দুটি সংখ্যা a এবং  b এর তফাৎ নিরূপণ করি।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 02:43&lt;br /&gt;
|তারপর আমরা তফাৎ প্রিন্ট করি।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 02:45&lt;br /&gt;
|  এটি আমাদের '''main''' ফাংশন।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 02:48&lt;br /&gt;
|  এখানে আমরা &amp;quot;add&amp;quot; ক্লাসের obj1 হিসাবে একটি অবজেক্ট তৈরী করি।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 02:53&lt;br /&gt;
|তারপর আমরা উভয় &amp;quot;input&amp;quot; এবং &amp;quot;numbers&amp;quot; ফাংশন obj1 অবজেক্ট ব্যবহার করে কল করি।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 02:59&lt;br /&gt;
|  তারপর আমরা &amp;quot;sub&amp;quot; ক্লাসের obj2 হিসাবে একটি অবজেক্ট তৈরী করি।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 03:04&lt;br /&gt;
|এখন দুটি ফাংশন অবজেক্ট obj2 ব্যবহার করে কল করি&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 03:08&lt;br /&gt;
|  এবং এটি আমাদের রিটার্ন স্টেটমেন্ট।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 03:10&lt;br /&gt;
|  এখন প্রোগ্রাম এক্সিকিউট করি।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 03:13&lt;br /&gt;
|  আপনার কীবোর্ডে Ctrl, Alt এবং T একসাথে টিপে টার্মিনাল উইন্ডো খুলুন।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 03:21&lt;br /&gt;
|  কম্পাইল করতে লিখুন, g++ স্পেস abstract ডট cpp স্পেস -o স্পেস abs&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 03:31&lt;br /&gt;
|Enter টিপুন।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 03:32&lt;br /&gt;
|লিখুন, ডট স্ল্যাশ abs&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 03:34&lt;br /&gt;
|Enter টিপুন।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 03:36&lt;br /&gt;
|  এটি Enter the numbers হিসাবে প্রদর্শিত হয়েছে।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 03:38&lt;br /&gt;
|আমি 9 এবং 4 লিখব।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 03:42&lt;br /&gt;
|প্রদর্শিত আউটপুট হল Sum is 13&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 03:46&lt;br /&gt;
|আবার আমরা দেখি Enter the numbers.&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 03:49&lt;br /&gt;
|আমি 8 এবং 3 লিখব।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 03:52&lt;br /&gt;
|প্রদর্শিত আউটপুট হল diff is 5&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 03:56&lt;br /&gt;
| আমরা টিউটোরিয়ালের শেষে চলে এসেছি।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 03:59&lt;br /&gt;
|স্লাইডে ফিরে আসি।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 04:01  &lt;br /&gt;
| সংক্ষেপে,&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 04:03&lt;br /&gt;
|এই টিউটোরিয়ালে শিখেছি:&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 04:04&lt;br /&gt;
| Abstract Class উদাহরণস্বরূপ class abstractinterface&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 04:09&lt;br /&gt;
| Pure Virtual Function উদাহরণস্বরূপ virtual void numbers()=0;&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 04:14&lt;br /&gt;
|  এখন, একটি abstract class &amp;quot;student&amp;quot; তৈরী করুন।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 04:17&lt;br /&gt;
| একটি Pure Virtual Function &amp;quot;Info&amp;quot; তৈরী করুন। &lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 04:20&lt;br /&gt;
| ফাংশনে শিক্ষার্থীর নাম এবং ক্রম সংখ্যা লিখুন।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 04:25&lt;br /&gt;
| দুটি ডিরাইভড ক্লাস marks এবং sports তৈরী করুন।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 04:29&lt;br /&gt;
|marks এ, তিনটি বিষয়ের মার্কস গ্রহণ করুন।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 04:32&lt;br /&gt;
|sports এ, খেলায় প্রাপ্ত মার্কস গ্রহণ করুন।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 04:35&lt;br /&gt;
|মার্কসের সমষ্টি গণনা করুন।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 04:38&lt;br /&gt;
|তারপর আরেকটি ডিরাইভড ক্লাস result তৈরী করুন।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 04:41&lt;br /&gt;
|এখানে, শিক্ষার্থীর নাম, ক্রম সংখ্যা এবং মার্কসের সমষ্টি প্রদর্শিত হয়।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 04:47&lt;br /&gt;
|  এই লিঙ্কে উপলব্ধ ভিডিওটি দেখুন।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 04:50&lt;br /&gt;
|এটি প্রকল্পকে সারসংক্ষেপে বোঝায়।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
| 04:53&lt;br /&gt;
|ভাল ব্যান্ডউইডথ না থাকলে ভিডিওটি ডাউনলোড করে দেখুন।&lt;br /&gt;
&lt;br /&gt;
|-&lt;br /&gt;
