Ayyuka a Haskell da Aikin Farko (+)
Haskell, kamar kowane yaren shirye-shirye, yana ba da daidaitattun ayyukan lissafi kamar ƙari, ragi, ninkawa, da rarrabawa. A cikin yanayinmu, muna sha'awar mafi sauƙi daga cikin waɗannan: Ƙarin aiki. Ana samun wannan ta amfani da aikin farko (+) a cikin Haskell.
Ana yin aikin ƙari tare da mai aiki (+). Furcin (x + y) yana ƙara x da y. Yi la'akari da wannan sauƙi Haskell code:
x = 5 y = 10 sum = x + y
Anan, muna da lamba biyu, 5 da 10, waɗanda aka sanya su zuwa masu canji x da y bi da bi. Sa'an nan kuma mu ƙara waɗannan lambobi biyu tare da x + y da kuma adana sakamakon a jimlar. Darajar jimlar za ta zama 15.
Bayanin mataki-mataki na Code
A faɗaɗa, lambar tana aiki a matakai masu hankali uku. Bari mu rushe shi don kyakkyawar fahimta:
- Layin farko, 'x = 5', yana bayyana mabambanta x kuma ya sanya masa ƙimar 5.
- Layi na biyu yana yin irin wannan aiki. Yana sanya darajar 10 ga mai canzawa y.
- Layi na uku, 'sum = x + y', shine inda aikin kari ke faruwa. Mai aiki da (+) yana ƙara ƙimar da aka adana a x da y, kuma ana sanya sakamakon zuwa jimlar mai canzawa.
Sauƙi da taƙaitaccen bayanin Haskell yana haskakawa sosai a nan, yayin da gabaɗayan aikin ƙari yana cikin layi ɗaya na lamba – 'sum = x + y'.
