Chii chikuitika apa?

Tsananguro

Kubva pana line 1, line 2, na line 3, tagadzira basa rinonzi mhoresaMunhu.

  • Zita re basa rinofana kunyorwa sekunge uri urikugadzira variable.
  • Pamberi pezita re basa panoiswa ma brackets (), muma brackets imomo munogona kuiswa ma variable kana kuti munogona kusaiswa chinhu, sezvaukuona pa code iyi.

Pa line 5:

tangaBasa.mhoresaMunhu()

Apa tiri kutuma computer kuita basa ratagadzira rinonzi mhoresaMunhu().Ma brackets () haasiiwe.

Basa ne ma variable#

Unogona kugadzira basa rinotora variable inozoshandiswa ne basa racho kana razotanga. Ngatomboti iwewe ukuda kugadzira basa rinomhoresa munhu asi ukuda kuzopa basa zita remunhu wekumhoresa. Unoita seizvi:

Chii chikuitika apa?

Tsananguro

Apa ukugadzira basa rinonzi mhoresaMunhu, asi ukuudza computer kuti kana basa iri rave kutangwa, rinofana kupihwa variable inonzi zita ichazoshandiswa na nyora("Hesi ", zita).
