Answer 1

C=current line
F=fixed line

Exercise #1:
=============
Errors in Declarations:
F:num rate -- missing

Errors in detailLoop() function:

C:if car_Type = "Compact" then
F:if carType = "Compact" then

C:if rate<>0
F:if rate<>0 then

   if days>=DAYS_FOR_DISCOUNT then
       rate=rate-rate*DISCOUNT_RATE
   endif
F:endif //missing

C:output carType,days
F:output "Rental fees for ",carType," car for ",days, " days is ",rate

C:output "Enter car type or ",QUIT, " to quit
C:" --not required
C:input car_Type -- not required as the input is handled via getReady()
F:getReady()

Exercise #2
===========
Main section:
C://Declarations
F:Declarations

C:OutputFile allsales
F:OutputFile allSales

C: while bothAtEof > "N"
F: while bothAtEof = "N"

getReady() Function:

C:newSalesperson = NAME
F:newSalesperson = HIGH_NAME

C:oldSalesperson = NAME
F:oldSalesperson = HIGH_NAME

C:bothAtEof < "Y"
F:bothAtEof = "Y"

detailLoop() Function:

C: usedSalesperson = HIGHNAME
F: usedSalesperson = HIGH_NAME

C: output newSalesperson, newAmount to alllSales
F: output newSalesperson, newAmount to allSales

finish() function:

C: close allsales
F: close allSales
