Liberty 基本工资计算器 IF ELSE

Question

我刚刚开始使用 Sams 学习基本编程，并且已经遇到了我一直在尝试编写的简单工资计算器的问题。有人可以解释我如何更好地重写这个吗？并且您只能在 IF THEN 语句之后使用打印命令吗？我想我必须投资一本更新的书，但我希望至少在此期间我可以让它运行。

Input "Please input payrate: "; Ans$
    Print
Input "Please input hours worked: "; Hrs$
If (Hrs$ >= "40") Then
    payRate = (Hrs$ * Ans$)
Else If (Hrs$ <= "41") Then
    payRate = Hrs$ * (1.5 * Ans$)
End If

taxRate = payRate * .15
grossPay = payRate * Hrs$
netPay = payRate - taxRate

Print

Print: "Your net pay is: "; netPay

Answer 1

我不使用 Liberty，但我想当您尝试对字符串进行数学运算时它会抱怨。此外，我发现您对“payrate”名称的滥用令人困惑。加班计算的逻辑也是错误的。这是我第一次尝试重写：

Input "Please input payrate: "; Rate$
Rate = val(Rate$)
Print
Input "Please input hours worked: "; Hrs$
Hrs = val(Hrs$)
Gross = Hrs * Rate
If Hrs > 40 Then Gross = Gross + ((Hrs - 40) * Rate / 2))
Taxes = Gross * .15
Net = Gross - Taxes
Print
Print: "Your gross pay is: "; Gross
Print: "Your net pay (after $";Taxes;" in taxes) is: "; Net

Answer 2

此代码将在 Liberty BASIC 中运行：

INPUT "Please enter hours worked: "; hours 'you don't need a dollar sign at the end of the variable because it's a value not a string
INPUT "Please enter your hourly rate: "; hourlyRate
gross = hours * hourlyRate 'works out the gross amount
IF (hours > 40) THEN 'if the person worked more than 40 hours, then the following command is applicable...
gross = 40 * hourlyRate + ((hours - 40) * (hourlyRate * 1.5)) 'this line calculates the money earned for 40 hours, and adds the remaining hours at 1.5 times the hourly rate
END IF 'end the IF condition
tax = gross * 0.15 'calculates the tax at 15%
net = gross - tax 'calculates the net pay (i.e., gross pay after tax)
PRINT "-------------------------------"
PRINT "Your gross pay is: "; gross
PRINT "Your net pay is: "; net

正如上一张海报所建议的那样，您应该在数学中使用值而不是字符串（值的末尾没有美元符号），并且当您标记变量时，它们应该具有与您的内容相关的有意义的名称正在努力实现。
