Question

A retail company must file a monthly sales tax report listing the total sales for the month and the amount of state and county sales tax collected. The state sales tax rate is 4 percent and the county sales tax rate is 2 percent. Write a program that asks the user to enter the total sales for the month. The application should calculate and display the following:

  • The amount of county sales tax
  • The amount of state sales tax
  • The total sales tax (county plus state)

Step 3:  Complete the pseudocode by writing the missing lines.  (Reference: Defining and Calling a Module, page 78-81).  Also, when writing your modules and making calls, be sure to pass necessary variables as arguments and accept them as reference parameters if they need to be modified in the module.  (Reference: Passing Arguments by Value and by Reference, page 97 – 103).                                      

 

Module main ()

     //Declare local variables

     Declare Real totalSales

     ______________________________________________________

     ______________________________________________________

     ______________________________________________________

     ______________________________________________________

    

     //Function calls

     Call inputData(totalSales)

     Call calcCounty(totalSales, countyTax)

     ______________________________________________________

     ______________________________________________________

     ______________________________________________________

End Module

 

//this module takes in the required user input

Module inputData(Real Ref totalSales)

     Display “Enter the total sales for the month.”

     Input totalSales

End Module

 

//this module calculates county tax

//totalSales can be a value parameter because it is not

//changed in the module.

//countyTax must be a reference parameter because it is

//changed in the module

Module calcCounty(Real totalSales, Real Ref countyTax)

countyTax = totalSales * .02

End Module

 

//this module calculates state tax
