00:01 | Ngi pdiangsngewbha iaphi sha ka Spoken Tutorial halor ka Referencing bad Dereferencing in Perl. |
00:07 | Ha kane ka jinghikai, ngin ia pule shaphang ki:
Scalar References Array References Hash References Dereferences bad Kumno ban add, remove, access ia ki elements jong ki array/hash references. |
00:22 | Na ka bynta kane ka jinghikai, nga pyndonkam da ka:
Ubuntu Linux 12.04 operating system Perl 5.14.2 gedit Text Editor |
00:33 | Phi lah ban pyndonkam kano kano ka text-editor katkum kamon jong phi. |
00:37 | Phi dei ban don ia ka jingtip shaphang ka:
Perl programming Array functions bad Hash functions. |
00:43 | Lada phim don, te sngewbha leit sha ki tutorials ba iadei ha ka Perl ha kane ka website. |
00:49 | Kaei ka Reference? |
00:51 | Ka reference kadei ka pointer lane ka address sha ka variable, array, hash lane ka subroutine. |
00:58 | Kam don lypa ia ka data ha ka. |
01:01 | Reference u scalar value barit bad basuk. |
01:05 | Reference kan pynbha ia ka jingtreikam jong u Perl code ynda phi pass lane pynphai ia ki data-structures ba heh. |
01:12 | Ka pynduna ia ka jingbam ka memory namar ka pass ia ka reference sha ka subroutine ban ia kaba ka pass ia u value. |
01:18 | Ka suk ban pynbit pynbiang ia ki Perl data structures kiba eh. |
01:22 | To ngin ia pule kumno ban shna ia ka reference. |
01:25 | Ngi lah ban shna ia ka reference na ka bynta kano kano ka variable, subroutine lane value, da kaba buh ia u backslash (\) hakhmat jong u. |
01:33 | U scalar variable udei u reference da u backslash bad u dollar sign ($) kumba la pyni hangne. |
01:39 | U array variable udei u reference da u backslash bad u at the rate(@) symbol. |
01:45 | U hash variable udei u reference da u backslash bad u percentage(%) symbol kumba lah pyni ha kane ka nuksa. |
01:53 | Kaei ka dereference? |
01:55 | Ynda u reference u shah dereference, u value uba dei u la shah pynphai. |
02:00 | Dereference lah leh da kaba buh ia u reference variable hapoh ki curly brackets |
02:06 | Bad hashwa u curly bracket ba sha kadiang bad u character ba la pynithuh ia u jait reference. |
02:12 | To ngin ia peit kumno ban dereference ia ki variables. |
02:16 | U scalar variable la dereferenced da u dollar sign ($) bad ki curly brackets. |
02:21 | U array variable la dereferenced da u at the rate (@) symbol bad ki curly brackets. |
02:27 | U hash variable la dereferenced da u percentage(%) symbol bad ki curly brackets. |
02:33 | To ngin ia peit ia ka simple program na ka bynta ka Scalar reference bad dereference. |
02:38 | To ngan plie ia ka sample program ha ka 'gedit' Text editor. |
02:43 | Plie ia ka terminal bad type: gedit scalarRef dot pl ampersand bad shon Enter. |
02:50 | Type ia u code harum kumba la pyni ha ka screen. |
02:55 | To ngan batai ia u code. |
02:57 | U lain ba nyngkong u declare ia u scalar variable '$a' bad la initialized sha 10. |
03:03 | Kumba la batai hashwa, u scalar variable udei u reference da u backslash bad u dollar sign ($). |
03:10 | Kane ka lain kan print ia ka memory address jong u variable uba lah shna kum u reference. |
03:16 | Ban print ia u value badei, u variable u dereference da ki curly brackets ba lah buh hashwa da u '$'. |
03:23 | Hangne, uref() function un sa pynphai ia u jait reference kum u scalar lane array lane hash. |
03:30 | Mynta, shon Ctrl+S ban save ia ka file. |
03:34 | To ngin ia execute ia ka program. |
03:36 | Phai sha ka terminal bad type: perl scalarRef dot pl bad shon Enter. |
03:43 | Ka output kadei kumba la pyni. |
03:46 | Ka lain ba nyngkong ka pyni ia ka memory address ha kaba la buh ia u value 10. |
03:51 | Ka lain kaba ar ka pynphai ia u value kaba dei 10. |
03:55 | Ref() function ka pynphai ia u "SCALAR" kum ka output. |
03:59 | Hadien kane, to ngin ia pyrshang ban sngewthuh kumno ban shna ia ka reference bad dereference array da kaba pyndonkam ia ka sample program. |
04:07 | Nga lah don lypa ia ka sample program. To ngan plie ia ka ha ka 'gedit' Text editor. |
04:13 | Ha ka terminal, type: gedit arrayRef dot pl ampersand bad shon Enter. |
04:20 | Type ia u code harum kumba la pyni ha ka screen, ha ka arrayRef dot pl file. |
04:26 | To mynta ngan batai ia u code. |
04:28 | Hangne, ha ka lain ba nyngkong, nga lah declared ia u array @color bad initialized ia u da lai tylli ki values. |
04:35 | La reference da u backslash @color kaba dei ka kyrteng jong ka array bad la assign sha u $colorRef. |
04:42 | Ka print statement kan print ia ka reference value bad ka dereference value. |
04:47 | Mynta, shon Ctrl+S ban save ia ka file. |
04:51 | To ngin ia execute ia ka program. |
04:53 | Phai biang sha ka terminal bad type: perl arrayRef dot pl bad shon Enter. |
05:00 | Ka output kadei kumba la pyni hangne. |
05:04 | Ka lain ba nyngkong ka pyni ia ka output jong ka memory address jong u variable ba lah shna kum ka reference. |
05:10 | Ka lain ba ar ka pyni ia ka value badei kata ka dereference. |
05:16 | Hadien kane, ngin sa iapeit kumno ban declare ia ka direct reference na ka bynta ka array. |
05:21 | To ngin ia phai biang sha ka program jong ngi. |
05:24 | Nga lah pyn kylla ia ka program ba lah don lypa ban pyni ia ka direct reference na ka bynta ka array. |
05:29 | Phi lah ban shna ia u direct reference na ka bynta ka array da kaba pyndonkam ia u square brackets [] kumba la pyni. |
05:35 | Pyndonkam arrow operator (->) ban dereference. |
05:39 | print statement kan sa print "Green" kum ka output. |
05:43 | Hangne, ka print statement ka shim ia u value jong ka index[1]. kata 'Green' ha ka program jong ngi. |
05:50 | Shon Ctrl+S ban save ia ka file. |
05:54 | Phai biang sha ka terminal bad type: perl arrayRef dot pl bad shon Enter ban execute. |
06:03 | Ngan pyni ia ka nuksa halor kumno ban pyndonkam ia ka direct hash reference ha kajuh ka code file.
Te, to ngin ia phai sha ka gedit. |
06:11 | Phi lah ban shna ia ka direct reference ban hash da kaba pyndonkam ia ki curly brackets {} kumba la pyni hangne. |
06:18 | Pyndonkam arrow operator (->) ban dereference ia u. “Name” udei u hash key. |
06:24 | Ha kapor ba execute ia une u block jong u code, baroh ar ki print statements kin print "Sunil" kum ka output. |
06:31 | Hadien kane ngin sa iohi kumno ban pyndap, weng, access ia ki elements sha ka array reference da ka sample program. |
06:39 | Nga lah don lypa ia ka sample program. To ngan plie ia ka ha ka gedit text-editor. |
06:45 | Plie ia ka terminal bad type: gedit arrayRefadd dot pl ampersand bad shon Enter. |
06:54 | La plie mynta ia ka 'arrayRefadd.pl' file ha ka gedit. Type ia u code kumba la pyni hangne, ha ka file jong phi. |
07:02 | Ka lain ba nyngkong ka pynsdang ia ka array. |
07:06 | Ngi lah reference ia u array da u backslash @numarray bad la assign sha u $ref. |
07:13 | Mynta, ngin sa iohi kumno ban access ia kawei ka element na ka array reference. |
07:19 | Ngi donkam ban pyndonkam ia u array index ha ki square brackets “[ ]” ban access ia u value bad u arrow operator (“->”) ban dereference ia u. |
07:28 | Ka print statement kan print ia u value jong ka index [0]. |
07:32 | push() function ka pyndap ia ki elements ha ka position ba khatduh jong ka array reference.
Ha ka bynta jong ngi, 5, 6, 7 lah pyndap sha bakut jong ka array ba lah don lypa 1, 2, 3, 4. |
07:47 | Kane ka print statement ka pyni ia ka output, hadien ba lah dep pyndap sha ka array reference. |
07:53 | pop() function ka weng ia ka element na ka position ba khatduh jong ka array reference. |
07:58 | Ha ka nuksa jong ngi, 7 un sa shah weng na ka array reference ba lah don lypa. |
08:03 | print statement kan sa pyni ia ka output hadien ba lah dep pyndam na ka array reference. |
08:08 | Mynta, shon Ctrl+S ban save ia ka file. |
08:11 | To ngin ia execute ia ka program. |
08:14 | Phai biang sha ka terminal bad type: perl arrayRefadd dot pl bad shon Enter. |
08:22 | Ka output kadei kumba la pyni hangne. |
08:26 | Mynta, to ngin ia peit ia kawei pat ka sample program ban pyndap, weng, access ia ki elements jong u hash reference. |
08:34 | Ha ka terminal, type: gedit hashRefadd dot pl ampersand bad shon Enter. |
08:42 | Kane kan sa plie ia ka file 'hashRefadd.pl' ha ka gedit. |
08:47 | To ngan batai ia ka sample program. |
08:50 | Nga lah declared ia u direct hash reference uba lah ban buh ha u scalar variable $weektemp. |
08:57 | Nga lah pyndonkam ia ki curly brackets ban mihkhmat ia u hash reference bad u arrow operator ban dereference. |
09:04 | Une u code u buh ia ki values jong ka temperature naduh Monday haduh Friday. |
09:09 | Nga pyndonkam ia ki “keys” built-in function ban loop ia ki keys jong u hash. |
09:15 | print statement kan print ia man u element jong u hash. |
09:19 | Ngi lah ban access ia u value jong u element kumba la pyni hangne. |
09:25 | print statement kan print ia ka temperature ha ka sngi Monday. |
09:29 | Mynta, save ia ka file. |
09:32 | Phai sha ka terminal bad type: perl hashRefadd dot pl bad shon Enter ban iohi ia ka output. |
09:41 | Ki hash keys bad ki hash values lah buh ha ka random order. |
09:46 | Ka output ba lah pyni kam iadei bad ka order ha kaba lah pyndap ia ki. |
09:52 | Da kane, ngi poi sha kaba kut jong kane ka jinghikai. To ngin ia batai kyllum. |
09:57 | Ha kane ka jinghikai, ngi lah pule shaphang ki:
Scalar References Array References Hash References Dereferences bad Kumno ban pyndap, weng, access ia ki elements jong ki array/hash references ryngkat ki nuksa. |
10:14 | Hangne ka kam na ka bynta jong phi. Pyndap ia ki keys ba thymmai “Saturday” bad “Sunday” ha u hash weektemp, ha ka hashRefadd dot pl file. |
10:24 | Pyndam ia u “Saturday” key ha kaba kut. |
10:27 | Print hash weektemp. |
10:30 | Save bad execute ia ka program. Mynta check ia ka result. |
10:35 | Ka video ha ka link harum ka kyllum lang ia ka Spoken Tutorial project. Sngewbha download bad peit ia ka. |
10:42 | Ngi pynlong ia ki workshops bad ai ia ki certificates sha kito kiba pass ha ka online test. Na ka bynta ki jingtip ba bniah, sngewbha thoh sha ngi. |
10:51 | Ia ka Spoken Tutorial project la bei tyngka da NMEICT, MHRD, Sorkar India.
Kham bun ki jingtip halor kane ka mission kidon ha kane ka link ba la ai. |
