O.k. this is my first scripting class and I need someone's opinion on this code. I need to write a code for a modularized program that will:
1.) read each record from the inventory database
2.) print a price tag for each item in inventory
3.) count and print the total number of tags printed
4.)sum and print the total retail value of the inventory in the store
Here's the code I came up with. Please tell me if it is correct or not.
start
perform housekeeping ('This will declare variables perform housekeeping ) (with read)
while not eof
perform mainLoop (‘This will read each record from the database)
perform calculateTotalretailvalue ( )
endwhile
perform finishup ( )
stop
housekeeping ( )
declare variables
invRecord
char invDescription
num invItemnumber
num invQuantity
num invRetailprice
num invTotalretailvalue
num invTotaltags
char mainHeading = "INVENTORY REPORT"
char columnHead1 =
"ITEM RETAIL PRICE QUANTITY DESCRIPTION"
char columnHead2 =
"TOTAL RETAIL VALUE TOTAL TAGS ITEM NUMBER"
num totalRetailvalue
open files
INVENTORY , Printer
print mainHeading
print columnHead1
print columnHead2
read invRecord
return
mainloop ( )
Read the first record
While not eof
Print fldItemnumber , fldDescription , fldQuantityonhand , fldRetailPrice
ItemCount = ItemCount +1
Totalretailvalue = (fldQuantity * fldRetailprice )
endwhile
Read next record
Loop
Print “Retail price : “ & ItemCount
Print “Value of Inventory = “ & Totalretailvalue
return
calculateTotalretailvalue ( )
Totalretailvalue = (fldQuantity * fldRetailprice )
return
printTotalretailvalue ( )
print Totalretailvalue
return
finishup ( )
close files
INVENTORY , Printer
return
