将数组中的数字放入包含 VB 中的计算的子例程

Question

所以我需要让控制台应用程序询问用户姓名、工作时间和工资率。这些答案将存储在适当的数组中。我需要在子例程中包含的计算中使用小时数和工资率数组中的信息。我试图通过我的教科书或在线找到某种提示，但在这种情况下我似乎找不到任何对我有帮助的东西......

我不明白我在以下几行中遇到的错误。

total = overtimePay(hours(i), rate(i))
total = regularPay(hours(i), rate(i))

我得到的错误是：

"Value of type 'Double' cannot be converted into a '1-dimentional array of Double'

当我把计算方程而不是子程序放在这里时，我的程序完全可以运行

这是我的全部代码。

Answer 1

调用函数时，参数不是数组，而是数组中的双精度值。所以你的两个函数不应该有参数 "ByVal array2() as double"，而应该只是 "hours as double"（对于 array1）和 "rate as double"。到那时，您将不需要数组中的 i 索引，因为您没有传递数组。

然后在函数内的一行中，不要使用 "array2(i)"，只需使用 "rate"，而不是 "array1(i)"，只需使用您的参数名称 "hours"

Answer 2

您没有传递数组，您传递的是数组中的一个值，hours(i) 是数组 hours 中元素 i 的双精度值
