Lokhu kuzoba isitolimende sokuqala se-Programming ePerl, le nto izosetshenziselwa umbukiso eBarCamp Milagro lapho ngizoba umbonisi khona, uyihlukanise izingxenye zayo ukuze ungenzi okuthunyelwe kube kukhulu kakhulu, ngiyethemba uyakuthanda.

Wonke amafayela ashiwo ku-athikili angalandwa kulesi sixhumanisi:

Okwenzela ukukhonza uPerl

I-Perl wulimi olunezinhloso eziningi, lapho bangenziwa khona kusuka kuzikripthi ezincane ukuphatha amaseva ngokuya nge Unix o I-GNU / Linux, ukwenza amakhasi wewebhu, kunamaphrojekthi aphelele enziwe ePerl

Izindawo Zokuthuthuka

Njengamanje emakethe kunezindawo eziningi zentuthuko ezingahlelelwa ku-perl esingazibala ngamagama:

1.- SublimeText (iWindows ne-GNU / Linux)

2.- I-Eclipse (iWindows ne-GNU / Linux)

3.- I-OpenPerlIDE (iWindows)

4.- Incwajana ++ (Windows)

Uhlobo Lokuguquguqukayo

Ku-Perl njengakuzo zonke izilimi zokuhlela kunezinhlobo ezahlukahlukene zokuhlukahluka

* Izikali. Okuguqukayo kuqala ngo- $, njengokuhluka kwe- $. Izintambo zombhalo noma izinombolo zimelwe lapha.

* Ukufika. Ukuhlelwa kuqala ngo- @, njenge- @variable. Ungafaka noma yini oyifunayo ngaphakathi.

* Hash. Ama-hashes aqala ngo-%, njengokuhluka kwe-%. Kokubili okuguqukayo nedatha kungaba yinoma yini.

Isikali

$var1 = 33; #Esto es una Variables Global

My var=32; #Esto es una Variable Local

I-Arrays

@array = ( “uno”,”dos”,”tres” ); #Array 3 elementos

@array=(); #Array de x elementos (Indefinido)

Hash

%hash = ( 1, "uno", 2, "dos", 3, "tres" );

Umsebenzi wokuphrinta

Umsebenzi ukuphrinta njengolimi lohlelo lwe-C ++, lisetshenziselwa ukuphrinta intambo yombhalo noma okuqukethwe kokuguquguqukayo esikrinini

Uhlelo Lokuqala: HolaBarcamp.pl

Umsebenzi we-STDIN

Esikusebenzele C o C ++ kufanele bakhumbule umsebenzi iskena. Yebo, i-STDIN igcwalisa umsebenzi ofanayo wokuthola amanani afakwe ngekhibhodi, kepha ngokungafani ne-scanf lapho bekufanele siyitshele ukuthi yiliphi inani elizofakwa ne-STDIN, kufanele sikwenze lokhu kuphela:

$variable=<STDIN>;

Nge-STDIN ungafaka umbhalo, inombolo, i-alphanumeric, konke lokhu ngaphandle kokuchaza ukuthi kwenziwa kanjani nge-scanf:

scanf(“%d”, variable_tipo_entera);

Uhlelo Lwesibili: WelcomeAlBarcamp.pl

Uhlelo Lwesithathu: Basic Operations.pl

Ngokufunda okungenhla manje singenza uhlelo olwenza imisebenzi emine eyisisekelo

UMA isitatimende

Isitatimende se-IF, njenganoma yiluphi ulimi lohlelo, sisetshenziswa lapho sifuna ukwenza ukuqinisekiswa noma sidinga inqubo ezokwenziwa lapho kuhlangatshezwana nesimo.
