Time	Narration
00:01	Ngi pdiangsngewbha ia phi sha ka “Scope of variables in C and C++”.
00:08	Ha kane ka jinghikai, ngin pule shaphang.
00:11	Kaei ka Scope jong u variable?
00:13	Kaei ka Global variable?
00:16	Kaei ka Local variable?
00:19	Katto katne ki nuksa.
00:22	Ngin peit ruh katto katne ki jingbakla bad ki solutions.
00:27	Ban record ia ka ne ka jinghikai, Nga pyndonkam da ka:
00:30	Ubuntu Operating System version 11.04, gcc and g++ Compiler version 4.6.1.
00:41	To ngin sdang da tien sdang jong ka scope of variables.
00:47	Ka dei ka bynta jong u code hapoh ha kaba u variable un lah ban accessed.
00:54	Ka shong ha ka jait bad jaka jong ka declaration la phiah ha ki ar bynta:
00:59	Global Variable bad
01:02	Local Variable.
01:05	Mynta ngin peit lyngba ki nuksa.
01:07	Nga lah dep type ia ka prokram halor ka editor.
01:10	To ngin plie ia ka.
01:14	Kynmaw ba ka kyrteng ka phail jong ngi ka dei “scope.c.”
01:19	To ngan batai ia ka code mynta.
01:23	Kane ka dei ka “header phail” jong ngi.
01:26	Hangne ngi lah declared ar tylli ki global variables “a bad b.”
01:32	Bad ngi lah “initialized” ia ki da kaba assign ia ki values kum “5 bad 2.”
01:39	Ka global variable ka don ha baroh ki functions hapoh ki prokram jong phi.
01:44	Ia kine la declared shabar jong kino kino ki functions, hajrong ka main() function.
01:51	Kine ki don ka “global scope.”
01:53	Hangne ngi lah declared ia ka “function” “add” “without” “arguments.”
01:59	Hangne “sum” ka dei ka local variable, la declared ia ka hapoh ka function “add”.
02:07	Ka local variable ka don tang ha ka function hapoh ha kaba la declared.
02:13	Kine ki variables la declared hapoh ka block.
02:16	Kine ki don ha “local scope”.
02:19	Nangta ka sum jong u a bad b yn buh hapoh ka variable ‘sum’. Hangne ngin print ia ka sum.
02:29	Kane ka dei ka “main()” function jongngi.
02:33	Ka “add” function la shim bad hadien sa execute.
02:38	Bad kane kadei ka “return” statement jong ngi.
02:40	Mynta click Save.
02:43	To ngin execute ia ka prokram.
02:45	Sngewbha plie ia ka terminal window da kaba press “Ctrl, Alt” bad “T” keys ha kajuh ka por na ka keyboard jong phi.
02:55	Ban compile, type 'gcc space scope.c space hyphen o space sco” bad press Enter.
03:05	Ban execute,Type “./sco” (dot slash sco), nion Enter.
03:10	Ka output la pyni kum
03:13	Sum of a and b is 7.
03:16	Mynta to ngin peit kumno ban execute ia ka juh ka prokram ha ka C++.
03:20	Phai biang sha ka prokram jong ngi. Nyngkon nion “Shift, Ctrl” bad “S” keys ha kajuh ka por na ka keyboard jong phi.
03:31	Mynta save ia ka phail kaba don ka extension “.cpp”(dot cpp) bad click Save.
03:41	To ngin pynkylla ia ka header phail kum “iostream”.
03:47	Mynta kynthup lang ia ka “using” statement. Click save.
03:58	Ka declaration jong ka global variable bad ka local variable ka long kum juh ha ka C++
04:03	Namar kata, ym donkam ban pynkylla ei ei.
04:07	Mynta bujli ia ka “printf” statement da ka “cout” statement.
04:13	Pyndam ia ka “format specifier” bad '\n'.
04:17	Mynta pyndam noh ia u comma.
04:19	Type ar tylli ki opening angle brackets.
04:22	Pyndam noh ia u closing bracket, type biang sa ar tylli ki opening angle brackets.
04:26	Bad hapoh ki double quotes type backslash n. Mynta clock Save.
04:35	To ngin execute ia ka prokram.
04:39	To ngin phai biang sha ka terminal.
04:42	Ban compile, type “g++ space scope dot cpp space –o space scol”
04:52	Here we have sco1 because we don't want to overwrite output parameter sco for the file 'scope.c'.
05:04	Mynta nion Enter.
05:07	Ban execute type “./scol” bad nion Enter.
05:14	Ia Ka output la pyni kum “Sum of a and b is 7”.
05:19	Ngin iohi ba ka iasriem ia u C code jong ngi.
05:27	Mynta ngin iohi katto katne ki jingbakla ba ngi ju shem.
05:31	To ngin phai biang sha ka pokram jong ngi. Tharai hangne ngan declare biang sa shisien ia u variable “a”
05:41	Type “int a” bad u semicolon.
05:45	Click Save. Ngi lah declared ia u variable ‘a’ halor ka main() function bad ha dien ka “add” function.
05:55	To ngin peit jia aiu.
05:57	Ngin phai biang sha ka terminal jong ngi.
06:01	Mynta compile biang kumba mynshuwa.
06:05	Ngin iohi ia ki jingbakla, “redefinition jong “int a” “,” ‘int a’
06:18	'“a” u dei u global variable.
06:20	Ka don ka “global scope.”
06:22	Ngim lah ban declare ia ka variable arsien namar lah dep declare ia ka globally.
06:27	Ngin lah ban declare ia ka “variable a” kum ka local variable.
06:34	To ngin pynbeit ia ka jingbakla.
06:36	Pyndam ia kane.
06:39	Click Save.
06:41	To ngin execute biang.Ngin phai biang sha ka terminal jong ngi.
06:45	Mynta compile biang kumba mynshuwa, execute kum mynshuwa.
06:49	Hoid, ka la treikam.
06:52	Da kane ngi lah poi sha kaba kut jong ka jinghikai.
06:56	To ngin batai lyngkot.
06:58	Ha kane ka jinghikai ngi lah tip,
07:00	Ka Scope of variable.
07:02	Global variable, e.g: int a=5 &
07:07	Bad local variable , e.g: int sum
07:12	Lyngba ka assignment,
07:14	Thoh ia ka prokram ban print ia ka jingiapher jong artylli ki number.
07:19	Peit ia ka video ba la ai ha ryngkat ka link ba la pyni harum.
07:22	Ka batai lyngkot ia ka Spoken Tutorial Project.
07:25	Lada phim don ka bor internet ba khlain, shu download sa peit pat hadien.
07:30	Ka Spoken Tutorial Project Team
07:32	ka pynlong ki workshop da ba pyndonkam ia ki spoken tutorials.
07:35	Yn ai syrnod ia kiba pass ia ka online test.
07:40	Na bynta ka jingtip ba kham bniah, sngewbha thoh sha ka 'contact@spoken-tutorial.org
07:47	Spoken Tutorial Project ka dei ka bynta jong ka Talk to a Teacher.
07:52	La kyrshan ia kane ka project da ka National Mission on Education lyngba ICT, MHRD, jong ka sorkar India.
08:00	Shuh shuh ki jingtip halor kane ka mission phin ioh na kane ka link ba la ai harum :
08:04	La pynkylla sha ka ktien khasi da i Godwin pyrbot
08:08	Khublei naka bynta ba iasnohlang
