Time Narration
00:01 Pdiang sngewbha ia phi sha ka spoken tutorial halor ki Constructors and Destructors ha ka C++.
00:07 Ha kane ka jinghikai, Ngin sa pule ia ki:
00:09 * Constructors
00:10 * Ki jait jong ki constructors
00:12 * Destructors.
00:13 Ngin leh ia kane da ka jingiarap jong ki katto katne ki nuksa.
00:17 Ban record ia kane ka jinghikai, Nga pyndonkam:
00:20 * Ubuntu Operating System version 11.10,
00:23 * g++ Compiler version 4.6.1
00:28 To ngin sdang da ka jingpynithuh sha ka Constructor.
00:31 Ka constructor ka dei ka dkhot function .
00:33 Ka don ia ka juh ka kyrteng kum ka class name.
00:37 Constructors kim lah ban pynphai ia ki value.
00:40 Ia ka la khot hi automatic ha ka por ba thaw ia ka object.
00:44 Ki jait jong ki Constructors :
00:46 * Parameterized Constructors
00:49 * Copy Constructors bad
00:50 * Default Constructors.
00:53 To ngin iaid sha ki Destructors.
00:56 Ia ki Destructors la pyndonkam ban pynkhuid ia ka memory ba la dep ai.
00:59 La khot ia kine ha ka por ba pynpait ia ka object.
01:02 U destructor u khlem shim arguments bad u khlem don ia ka return types.
01:07 To ngin peit ia ka nuksa halor ki Constructors bad ki Destructors.
01:11 Nga la dep type lypa ia ka code ha ka editor, ngan plie ia ka.
01:15 Buh kynmaw ba ka filename jong ngi ka dei ka cons hyphen dest dot cpp.
01:20 Ha kane ka program, Ngin leh ia ka jingkheinlang jong artylli ki nombar da kaba pyndonkam da ka constructor.
01:25 Ai ngan batai ia ka code mynta.
01:27 Kane kadei ka header file jong ngi kum iostream.
01:30 Hangne ngi la pyndonkam std namespace.
01:33 Nangta ngi don ia ka class Addition. a bad b ki dei integer variables.
01:38 Kine ki dei ki dkhot private jong ka class Addition.
01:42 Hangne ngi don ia ka Public specifier.
01:44 Nangta ngi don ia u construtor Addition.
01:47 U constructor u don ia kajuh ka kyrteng kum ka kyrteng ka class.
01:52 Ngi la dep ai ar tylli ki arguments hangne.
01:54 Mynta ngi la dep thaw ia u Destructor.
01:57 Na bynta kane ngi pyndonkam ia ka tilde sign bud da ka kyrteng kidestructors.
02:02 Kane ka dei ka public function add.
02:05 Ka pynphai ia ka jingkhien lang jong a bad b.
02:08 Hangne, ngi ioh pyndonkam ia u constructor da kaba pyndonkam ia u scope resolution operator.
02:12 a bad b ki dei ki dkhot private.
02:15 ban ioh pyndonkam ia ki dkhot private, ngi pyndonkam x bad y.
02:19 Nangta ngi pyndonkam ia u destructor.
02:21 ha kane , ngi print "Memory Deallocation".
02:25 Kane kadei ka main function. Jong ngi.
02:28 Hangne, ngi thaw ia ka object obj jong class Addition.
02:32 nangta ngi ai ar arguments kum 3 bad 4.
02:36 3 yn sa buh ha u x bad 4 yn sa buh ha u y.
02:40 Kane ka mut ba ka jingdon u a ka dei 3 bad ‘’'b'’’ ka dei 4.
02:45 U constructor ba don arguments la khot parameterized constructor.
02:50 Dei na kata ba une uwei u dei u prameterized constructor.
02:53 Hangne, ngi khot ia u function add da kaba pyndonkam ia ka obj.
02:58 bad ngi print ia ka jingkheinlang.
03:00 Kane ka dei ka return statement jong ngi.
03:02 Mynta to ngin execute ia ka program.
03:05 Plie ia ka terminal window da kaba nion Ctrl, Alt bad T keys ryngkatlang ha ka keyboard jong phi.
03:12 Ban compile, type: g++ space cons hyphen dest dot cpp space hyphen o space cons
03:21 Press Enter.
03:23 Type: dot slash cons
03:25 Nion Enter.
03:27 La pyni ia ka output kum:
03:29 Sum is 7 bad Memory Deallocation.
03:33 Mynta to ngin peit ia ka nuksa halor ka Default constructors.
03:37 Wanphai biang sha ka program jong ngi.
03:39 Nga la dep type lypa ia ka code.
03:41 Buh kynmaw ba ka kyrteng jong ka file jong ngi ka dei default dot cpp.
03:45 Lada ia u constructor la khlem pynbna ne declare ha ka class
03:48 nangta ka compiler kan shu thaw ia u default constructor na bynta ka class.
03:53 Ai ngan batai ia ka code.
03:55 Kane ka dei ka header file jong ngi kum iostream.
03:58 Hangne ngi la dep pyndonkam std namespace.
04:02 Nangta ngi don ia ka class Subtraction.
04:04 Nangta ngi don ia u a bad b ba la pynbna kum public.
04:08 Hangne, ngi don sub function.
04:10 Ngi la ai ar tylli ki arguments int a bad int b.
04:15 Kane ka pynphai ia ka jingshimnoh jong artylli ki number a bad b.
04:19 Kane ka dei ka default constructor.
04:22 Hangne, ngi ioh pyndonkam ia u default constructor da ka ba pyndonkam da u scope resolution operator.
04:27 Kane kadei ka main function jong ngi.
04:29 Ha kane, ngi la dep define ia u variable x.
04:34 Hangne ngi thaw ia ka object 's' jong ka class subtraction.
04:39 nangta ngi khot ia ka function sub da kaba pyndonkam da ka object s.
04:42 Bad ai ar tylli ki arguments Kum 8 bad 4.
04:47 Ia ka result la buh ha u variable x.
04:51 Bad hangne ngi print ia ka jingiapher.
04:54 Kane ka dei ka return statement jong ngi.
04:56 Mynta, to ngin execute ia ka program.
04:58 Wanphai biang sha ka terminal jong ngi.
05:01 To ngin compile, type: g++ space default dot cpp space hyphen o space def
05:09 Press Enter.
05:10 Type: dot slash def
05:12 Press Enter.
05:14 Ka output ka la wanphai kum:
05:16 Difference is 4.
05:18 Phai biang sha ka program jong ngi.
05:20 Hangne phi lah ban iohi ba ngi la ai ia ki arguments hapoh jong ka function.
05:25 Bad ha ka nuksa jong ngi ba hashwa kane, ngi la ai ia ki arguments hapoh jong ka Object.
05:30 Bad hangne ngi la dep ai ia ki arguments da kaba pyndonkam da ka Object.
05:34 Mynta, to ngin leit biang sha ki slides jong ngi.
05:38 To ngin ia batai lyngkot. Ha kane ka jinghikai ngi la pule shaphang ki:
05:41 * Constructor. eg, Addition
05:43 * Parameterized Constructor. eg. Addition obj (3, 4);
05:48 * Destructor. eg. ~Addition
05:52 * Default Constructor. eg. Subtraction
05:55 Kum ka assignment, thaw ia ka class ba kyrteng Division.
05:59 Thaw ia u constructor na bynta ka class.
06:01 Bad thaw ia ka function divide ba phiah ia ar tylli ki nombar ba la ai.
06:06 Peit ia ka video badon ha ka link ba pyni harum.
06:09 Ka batai lyngkot ia ka Spoken Tutorial project.
06:11 Lada phim don ia ka internet basted, phi lah ban download bad peit ia ka.
06:16 Ka Spoken Tutorial Project Team: ka pynlong ia ki workshop da ka ba pyndonkam da ki spoken tutorials.

.

06:21 Ai certificates ia kiba pass ha ka online test.
06:25 Na ka bynta jingtip ba khambniah, sngewbha thoh sha:
06:27 contact@spoken-tutorial.org
06:31 Spoken Tutorial Project ka dei ka bynta jong ka "Talk to a Teacher" project.
06:36 La kyrshan ia ka da ka National Mission on Education lyngba ICT, MHRD, Sorkar jong ka ri India.
06:42 Ki jingtip kiba kham bun halor kane ka mission lah ban ioh na kane ka link harum.
06:47 Nga dei u Thawlad miki bad la pynkylla ia kane ka script da I Arkijuh Dkhar, ngan pynkut noh..

Khublei ba phi la iashim bynta.
