没有为参数“thirdNumber”传递值

Question

如何修复此错误？

有趣的 main() {

println(add(10,7,9))

}

// 在该行下面定义 add() 函数

fun add(firstNumber: Int, secondaryNumber: Int, ThirdNumber: Int): String {

val result = add(firstNumber, secondNumber)
val anotherResult = add(firstNumber, thirdNumber)

return "$firstNumber + $secondNumber = $result"
return "$firstNumber + $thirdNumber = $anotherResult" 

}

Answer 1

我不太确定你想要实现什么，但一个选择可能是：

fun add(firstNumber: Int, secondNumber: Int, thirdNumber: Int): String {
  val result = firstNumber + secondNumber + thirdNumber
  return "$firstNumber + $secondNumber + $thirdNumber = $result" 
}
