A function named newProdCode needs to be defined that accepts two input parameters, an integer...

fun newProdCode{itemID: Number, productCategory: String) —> "PC-" ++ productCategory ++ (itemID as String)

fun newProdCode(itemID: Number, productCategory: String) = "PC-" ++ productCategory ++ (itemID as String)

function newProdCode(itemID: Number, productCategory: String) ="PC-" ++ productCategory ++ (itemID as String)

var newProdCode(itemID: Number, productCategory: String) ->"PC-" ++ productCategory ++ (itemID as String)
