Ternarinis operatorius<\/h1>\n

Trejetainis operatorius, dar vadinamas s\u0105lyginiu operatoriumi, yra sutrumpintas b\u016bdas u\u017era\u0161yti teigin\u012f if-else vienoje eilut\u0117je kodas<\/a>. Jis priima tris operandus: s\u0105lyg\u0105, reik\u0161m\u0119, kuri\u0105 reikia gr\u0105\u017einti, jei s\u0105lyga yra teisinga, ir reik\u0161m\u0119, kuri\u0105 reikia gr\u0105\u017einti, jei s\u0105lyga yra klaidinga. Trejetainio operatoriaus sintaks\u0117 yra tokia:<\/p>\n

s\u0105lyga ? value_if_true : value_if_false<\/code><\/p>\n

Pirmiausia \u012fvertinama s\u0105lyga. Jei ji yra teisinga, gr\u0105\u017einama i\u0161rai\u0161ka value_if_true. Jei ji yra klaidinga, gr\u0105\u017einama i\u0161rai\u0161ka value_if_false. Trejetainis operatorius da\u017enai naudojamas kaip glaustesn\u0117 if-else teiginio alternatyva tais atvejais, kai s\u0105lyga yra paprasta, o gaut\u0105 kod\u0105 lengva skaityti.<\/p>\n

Pavyzd\u017eiui, panagrin\u0117kite tok\u012f if-else teigin\u012f:<\/p>\n

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

Tai galima perra\u0161yti naudojant trejybin\u012f operatori\u0173 taip:<\/p>\n

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

Trejetainis operatorius taip pat gali b\u016bti \u012fterptas, kad b\u016bt\u0173 galima tvarkyti sud\u0117tingesnes s\u0105lygas. Pavyzd\u017eiui:<\/p>\n

rezultatas = (x > 0) ? \"Teigiamas\" : (x < 0) ? "neigiamas" : "nulinis";<\/code><\/p>\n

\u0160iuo kodu patikrinama, ar x yra didesnis u\u017e 0. Jei taip, gr\u0105\u017einama reik\u0161m\u0117 \"Teigiama\". Jei ne, kodas tikrina, ar x yra ma\u017eesnis u\u017e 0. Jei taip, gr\u0105\u017einama reik\u0161m\u0117 \"Neigiama\". Jei x n\u0117ra nei didesnis, nei ma\u017eesnis u\u017e 0, gr\u0105\u017einama reik\u0161m\u0117 \"Nulis\".<\/p>\n

Nors tam tikrais atvejais trejybinis operatorius gali padaryti kod\u0105 glaustesn\u012f ir lengviau skaitom\u0105, jis taip pat gali apsunkinti kodo supratim\u0105, jei naudojamas per daug arba netinkamai. Svarbu trejybin\u012f operatori\u0173 naudoti protingai ir pirmenyb\u0119 teikti kodo ai\u0161kumui ir tvarkymui, o ne glaustumui.<\/p>","protected":false},"excerpt":{"rendered":"
