Ternaarne operaator<\/h1>\n

Ternaarne operaator, mida tuntakse ka tingimusoperaatorina, on l\u00fchendatud viis if-else avalduse kirjutamiseks \u00fches reas kood<\/a>. See v\u00f5tab kolm operandi: tingimus, v\u00e4\u00e4rtus, mis tagastatakse, kui tingimus on t\u00f5ene, ja v\u00e4\u00e4rtus, mis tagastatakse, kui tingimus on vale. Ternaarse operaatori s\u00fcntaks on j\u00e4rgmine:<\/p>\n

tingimus ? value_if_true : value_if_false<\/code><\/p>\n

K\u00f5igepealt hinnatakse tingimust. Kui see on t\u00f5ene, tagastatakse v\u00e4ljend value_if_true. Kui see on vale, tagastatakse v\u00e4ljend value_if_false. Kolmikoperaatorit kasutatakse sageli kui \u00fclevaatlikumat alternatiivi if-else avaldisele olukordades, kus tingimus on lihtne ja saadud kood on kergesti loetav.<\/p>\n

N\u00e4iteks vaadelge j\u00e4rgmist if-else avaldust:<\/p>\n

if (x > 0) { y = x; } else { y = -x; }<\/code><\/p>\n

Seda saab \u00fcmber kirjutada, kasutades kolmikoperaatorit j\u00e4rgmiselt:<\/p>\n

y = (x > 0) ? x : -x;<\/code><\/p>\n

Kolmikoperaatorit saab ka keerulisemate tingimuste k\u00e4sitlemiseks sisseehitada. N\u00e4iteks:<\/p>\n

tulemus = (x > 0) ? \"Positiivne\" : (x < 0) ? "Negatiivne" : "Null";<\/code><\/p>\n

See kood kontrollib, kas x on suurem kui 0. Kui on, siis tagastatakse v\u00e4\u00e4rtus \"Positiivne\". Kui mitte, siis kontrollitakse, kas x on v\u00e4iksem kui 0. Kui on, siis tagastatakse v\u00e4\u00e4rtus \"Negatiivne\". Kui x ei ole suurem ega v\u00e4iksem kui 0, tagastatakse v\u00e4\u00e4rtus \"Zero\".<\/p>\n

Kuigi ternaarne operaator v\u00f5ib m\u00f5nel juhul muuta koodi \u00fclevaatlikumaks ja kergemini loetavaks, v\u00f5ib see liigse v\u00f5i ebasobiva kasutamise korral muuta koodi ka raskemini m\u00f5istetavaks. Oluline on kasutada kolmikoperaatorit m\u00f5istlikult ja seada koodi selgus ja hooldatavus l\u00fchiduse asemel esikohale.<\/p>","protected":false},"excerpt":{"rendered":"
