Ichi chichava chikamu chekutanga cheProgramming muPerl, chinyorwa ichi chicha shandiswa pakuratidzira paBarCamp Milagro uko ini ndichave muenzanisi, inochipatsanura kuita mativi kuitira kuti positi iite yakakura, ndinovimba unoifarira.

Ese mafaera ataurwa muchinyorwa anogona kutorwa pasi kubva pane iyi link:

Chii chekushandira Perl

Perl mutauro unowirirana, umo mavanogona kuitirwa kubva kumavara madiki ekugadzirisa maseva zvinoenderana Unix o GNU / Linux, Kunyangwe kugadzira mapeji ewebhu, pane mapurojekiti akazara akagadzirwa muPerl

Nharaunda dzekuvandudza

Parizvino mumusika mune nharaunda zhinji dzekusimudzira kuronga mu perl yatinogona kutumidza zita:

1.- SublimeText (Windows uye GNU / Linux)

2.- Eclipse (Windows uye GNU / Linux)

3.- OpenPerlIDE (Mahwindo)

4.- Notepad ++ (Windows)

Rudzi rweMisiyano

MuPerl senge mune chero mutauro mutauro pane akasiyana marudzi ezvimwe

* Scalars. Misiyano inotanga ne $, kunge $ kusiana. Tambo dzemavara kana manhamba anomiririrwa pano.

* Arrays. Arrays inotanga na @, senge @variable. Unogona kuisa chero chaunoda mukati.

* Hash. Ashes inotanga ne%, se% inoshanduka. Ose maviri akasiyana uye dhata inogona kuve chero chinhu.

Scalars

$var1 = 33; #Esto es una Variables Global

My var=32; #Esto es una Variable Local

Arrays

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

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

Hash

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

Dhinda basa

Basa racho dhinda sezvazviri muC ++ programming mutauro, unoshandiswa kupurinda tambo yemavara kana zvirimo zvemusiyano pachiratidziri

STDIN basa

Zvatakashandira C o C ++ vanofanirwa kurangarira mashandiro acho scanf. Zvakanaka, STDIN inozadzisa iro basa rimwe chete nderokugamuchira kukosha kwakapindirwa nekhibhodi, asi kusiyana nescanf umo yataifanira kuudza kuti ndeupi kukosha uchazopinzwa ne STDIN, isu tinongofanirwa kuita izvi:

$variable=<STDIN>;

Ne STDIN iwe unogona kuisa zvinyorwa, nhamba, alphanumeric, zvese izvi pasina kutsanangura kuti zvakaitwa sei ne scanf:

scanf(“%d”, variable_tipo_entera);

Chechitatu Chirongwa: Basic Operations.pl

Nezvakataurwa pamusoro apa isu tava kukwanisa kuita chirongwa chinoita mana ekutanga mashandiro

KANA chirevo

Chirevo cheI IF, senge mune chero mutauro mutauro, chinoshandiswa kana tichida kuona kuti zvodii kana kuti tinoda kuti chiitiko chiitwe kana mamiriro acho asangana.
