Caute vsetci, hladam pomoc ak sa niekto vyzna v programovani v Java Script, velmi mi to pomoze. Mam napisat program s vyuzitim troch paralelnych array funkcii na 1.nazov meny, 2.nazov kodu meny, 3.premenna. Toto maju byt spominane tri paralelne arrays. jedna sa o 4 meny USD, EUR, JPY, GBP takze Dollar, Euro, Japonsky jen, Libra. Dollar =1, Euro = 1.27Dollar, Libra = 1.87Dollar a Japonsky jen = 0.0085Dollar. podmienky su dalsie take ze ak stlacim 0 bude to dollar, 1 euro, 2 libra a 3 jen. Najprv sa podla preemennych samozrejme vynasobi vstupna mena premennou do Dollar a nakoniec vysledok sa deli menou ktora ma byt vysledna... Program som zmakol ukazuje ok vysledne hodnoty ale MUSIM pripojit k zaverecnemu vysledu pokec ze napr.12345 EUR je xyz GBP. Chybaju mi tam tie oznacenia meny. POMOZE MI NIEKTO PROSIM>??>>
