Time	Narration
00:01	Ngi pdiang sngewbha iaphi sha ka jinghikai halor ka Increment and Decrement Operators in C and C++.
00:08	Ha kane ka jinghikai, ngin pule shaphang ka:
00:10	Increment bad decrement operators.
00:12	'++' eg. a++ kaba dei ka postfix increment operator.
00:18	++a kaba dei ka prefix increment operator.
00:22	'--' eg. a-- ka dei ka postfix decrement operator.
00:27	--a ka dei ka prefix decrement operator.
00:31	Ngin pule ruh shaphang ka Typecasting.
00:35	Ban record ha kane ka jinghikai, nga pyndonkam da ka: Ubuntu 11.10 kum ka operating system,
00:40	gcc and g++ Compiler version 4.6.1 in Ubuntu.
00:48	Ka ++ operator ka pynkiew ia u value ba don jong ka operand da i wei.
00:54	a++ and ++a ka iaryngkat bad u a = a + 1.
01:00	Ka -- operator ka pynhiar ia u value ba don jong ka operand da i wei.
01:06	a--bad --a ki iaryngkat bad u a = a - 1.
01:13	Ngan pyni mynta kumno ka jingtreikam jong ka increment bad decrement operators da ka jing iarap jong ka C prokram.
01:19	Nga lah shna lypa ia ka prokram, Te ngan batai ia u code.
01:25	Hangne, ngi lah don u code jong ka increment bad decrement operators hapoh ka C.
01:30	Hangne, nga lah shim ia u integer variable a bad ia u value 1.
01:35	Ha kane ka rukom ngin lah ban khmih bniah ia ka jingkylla ha ka value jong u a.
01:39	Namarkata kan ai ha ngi ia ka jingmut kaba khambha shaphang ka jingtrei kam jong ki operators.
01:47	To ngin peit kumno ka postfix increment operator ka treikam.
01:51	Ka jingmih na kane ka printf statement kalong 1.
01:55	ka value kan ym kylla.
01:57	kane ka long namar ba ka postfix operation ka jia hadien bala evaluate ia ka operand.
02:04	Lada ka operation ka leh pynbiang halor jong ka a++, ka pynbiang ruh ia u value jong u 'a.
02:10	Hadien nangta u value jong u a la incremented.
02:17	Mynta lada ngi peit ia ka value jong u a hangne, lah increment da 1.
02:27	Sa shishien ngin initialize ia u 'a' sha u 1 khnang ba kan reflect halor ka jingkylla.
02:35	Mynta ngin phai biang sha ka prefix increment operators.
02:38	Kane ka printf statement kan print 2 ha ka screen.
02:42	Kane ka long namar ba ka prefix operation ka shait jia ha shuwa ban evaluate ia ka operand.
02:49	Te ka value jong u 'a' nyngkong eh la increment da 1 bad la print ia ka.
02:58	Sa shishien ngin print ia u 's value ban peit yn ym don shuh ki jingkylla.
03:03	Mynta to ngin check dakaba execute ia u code.
03:07	Ngan comment ia kine ki lain. Type /*, */
03:19	Click Save.
03:22	Nga lah save ia ka phail jongnga kum incrdecr.c.
03:29	Plie ia ka terminal window da kaba nion Ctrl, Alt and T keys ha kajuh ka por.
03:35	Ban compile, type ia kine halor jong ka terminal; gcc space incrdecr dot c space minus o space incr. Nion Enter.
03:51	Ban execute ia u code, type ./incr (dot slash incr). Nion enter.
03:59	Ia ka jingmih lah pyni ha ka screen.
04:01	Kane ka long ka jingmih haba phi lah print ia u a++.
04:06	Kane ka long ka jingmih haba phi lah print ia u ++a.
04:09	Ngin iohi ba ka jingmih ka long kumba ngi lah bishar hashuwa.
04:13	Mynta ngin phai biang sha ka prokram kaba sah.
04:16	Mynta ngan batai shaphang ka postfix bad ka prefix decrement operators.
04:21	Pyndam ia kia multi-line comments nangne nangne.
04:29	Mynta sa shisien ngin assign ia ka value jong u 1 sha u a.
04:35	Kane ka printf statement ka pynmih ia ka value jong u 1 kumba lah batai nyngkong.
04:40	a's value yn sa decremented hadien ba ia u a-- la evaluated namar ba ka dei ka postfix expression.
04:47	Ha ka next statement yn print ia u a's value kum u o.
04:51	a's value mynta lah decremented da 1.
04:54	Mynta ngi ioh ia ka prefix decrement operator.
04:58	Ka jingmih na kane ka printf statement kan long 0.
05:00	Namar ba ka dei ka prefix operation.
05:05	Ka prefix operation ka shait jia ha shuwa ban evaluate ia ka operand.
05:09	Ka jingmih na ka printf statement ka long 0.
05:11	Yn ym don jingkylla shuh ia u a's value.
05:15	Type return 0; bad close da u ending curly bracket.
05:21	Click Save.
05:24	Phai biang sha ka terminal.
05:27	Ban compile, type ia kine halor jong ka terminal; gcc space incrdecr dot c space minus o space incr. Nion Enter.
05:42	ban execute, type ./incr. Nion Enter.
05:52	Kane ka long ka jingmih haba print a--.
05:56	Kane ka long ka jingmih haba print --a.
05:59	Te, mynta ngin peit kumno ka increment bad decrement operator ka treikam.
06:05	Lada ngi kwah ban thoh ia ka juh ka prokram ha ka C++,
06:07	Nga lah ban pynkylla katto katne halor jong u C code.
06:10	To ngan phai biang sha ka editor.
06:13	Kane kadei ka C++ phail bad ki code badonkam.
06:16	Peitbniah ba ka header ka iapher na ka C phail header.
06:20	Ngi don ka using namespace statement ruh.
06:24	Khmih ruh ba ka jingmih na ka statement ha ka C++ ka long cout.
06:28	Te, nalor ka jingiapher jong kine , ki artylli ki code ki kham iasyriem.
06:33	Save ia ka phail. Ka phail la save lyngba ka extension .cpp.
06:40	To ngin compile ia u code.
06:42	Plie ia ka terminal bad type g++ space incrdecr dot cpp space minus o space incr. Nion Enter.
07:00	Ban execute, type ./ incr (dot slash incr). Nion Enter.
07:07	Ia ka jingmih la pyni ha ka screen.
07:10	Te, ngi iohi ia ka jingmih ka ialong kumjuh ha ka C program.
07:15	Mynta ngi ioh ia ka concept jong ka typecasting.
07:17	Ha kajuh ka rukom lah implement ia baroh ar ka C bad C++.
07:22	Ia ka Typecasting la juh pyndonkam kum ka wei na ki variable, leh kum ka wei pat ka jait.
07:27	La pyndep ia Typecasting da kaba buh ruh ia ka data type, ba phi kwah, hapoh jong ki
07:33	Ia ka cast la buh hakhmat jong u variable ba phi kwah ban cast.
07:38	Ka typecast ka long valid tang na ka bynta jong kawei ka operation
07:42	Mynta u a' un behave kum ka float variable, naka bynta ka wei ka operation.
07:47	Kane ka long ka nuksa kaba nga lah shna.
07:50	Mynta ngan batai ia u code.
07:54	Nyngkong ngin declare ia ki variables a and b kum ki integers bad c kum ka float.
08:00	a la assigned ia u value jong u 5. b la assigned ia u value jong u 2.
08:06	Ngin leh ia ka operation halor jong u a and b.
08:10	Ngin divide ia u a da u b. Ka jingmih na ka division la buh ha poh ka c.
08:14	Ngi lah pyndonkam ia ka %.2f ban pyni ia ka precision jong 2 decimal places.
08:20	Ka jingmih ba la pyni kan long 2.00 na ka jingkhmih lynti ia ka jingmih jong ka 2.50.
08:25	Ka fractional part lah truncated ha kaba baroh ar ki operands a and b ki dei ki integers.
08:31	Ban leh shisha da ka division, u wei na ki operands un dei u typecast to float.
08:35	Hangne ngi typecasting a to float. c mynta yn bat ia u value kum u real division.
08:41	mynta ka jingmih jong ka real division yn pyni. Ka answer ka long 2.50 kumba khmih lynti.
08:47	Type return 0; bad close u ending curly bracket.
08:51	Click Save. Save the file with .c (dot c) extension.
08:55	Nga lah save ia ka phail jong nga kum typecast.c.
08:59	Plie ia ka terminal.
09:01	Ban compile, type gcc space typecast dot c space minus o space type. Nion Enter.
09:17	Ban execute, type ./type. Nion Enter.
09:25	Ka jingmih yn pyni ha ka screen.
09:27	Haba peit ia ki ar tylli ki value ngi iohi ia kaba mih jong ka typecasting.
09:32	Mynta ngin batai lyngkot ia ka jinghikai.
09:34	Ha kane ka jinghikai ngi la pule-
09:36	Kumno ban pyndonkam ia ka increment bad decrement operators,
09:40	Ngi lah pule shaphang ki forms, Postfix and Prefix,
09:44	Bad ruh ngi lah pule shaphang ka typecasting bad kumno lah pyndonkam.
09:47	Kum ka assignment:
09:49	thoh ia ka program ban solve ia kine ki expression, a divided by b plus c divided by d.
09:56	Ki values jong u a, b, c bad d la shim kum ka input na u user.
10:01	Pyndonkam da ka typecasting ban perform real division.
10:05	Peit ia ka video ba la ai ha ka link harum.
10:08	Kan batai lyngkot shaphang ka Spoken Tutorial project.
10:10	Lada phim don ia ka bandwidth ba biang, phi lah ban download bad peit pat ia ka.
10:15	Ka Spoken Tutorial project team:
10:17	Ka pynlong ia ki jinghikai da kaba pyndonkam da ki spoken tutorials.
10:20	Yn ai syrnod ia kiba pass online test.
10:24	Na bynta ka jingtip ba kham bniah, sngewbha thoh sha ka: contact@spoken-tutorial.org
10:33	Spoken Tutorial project ka dei ka bynta jong ka Talk to a Teacher project.
10:37	La kyrshan ia kane ka project da ka National Mission on Education lyngba ka ICT, MHRD, jong ka sorkar India.
10:44	Shuh shuh ki jingtip halor kane ka mission phin ioh na kane ka link ba la ai harum: http://spoken-tutorial.org\NMEICT-Intro
10:55	La pynkylla sha ka ktien khasi da i Godwin pyrbot bad nga i John Nongkynrih. Khublei naka bynta ba iasnohlang.
