In the assignment below please fix the errors in each code. The first code should have a total of 3 erros. The second and third code should have 4 errors. Thanks

//DEBUG05-01
// This program is supposed to display every fifth year

Expert Solution

Note: In the below codes , error coorection have been shown by the bold letteres.

Debug 1:

start
   Declarations
      num year
      num START_YEAR = 2017
      num FACTOR = 5
      num END_YEAR = START_YEAR + FACTOR*29
   year = START_YEAR
   while year <= END_YEAR

year=year + 5
output year
endwhile
stop

Debug 2:

start
   Declarations
      num MONTHS = 12
      num YEARS = 30
      string MSG = "Remember to allow 5 days for mailing"
      num acctNum
      num yearCounter=1

num monthCounter=1
   housekeeping()
   while acctNum<> QUIT
      printCoupons()
   endwhile
   finish()
stop

housekeeping()
   print "Enter account number or ", QUIT, " to quit "
   input acctNum
return

printCoupons()
   while yearCounter <= YEARS
      while monthCounter <= MONTHS
         print acctNum, monthCounter, yearCounter, MSG
         monthCounter = monthCounter + 1
      endwhile

yearCounter= yearCounter+1
   endwhile
   output "Enter account number or ", QUIT, " to quit "
   input acctNum
return

finish()
   output "End of job"
return

Debug 3:

start
   Declarations
     num digit1 = 0
     num digit2 = 0
     num digit3 = 0
   while digit1 <= 9
      while digit2 <= 9
         while digit3 <= 9
            output digit1, digit2, digit3
            digit3 = digit3 + 1
         endwhile
         digit2 = digit2 + 1

digit3 = 0
endwhile
digit1 = digit1 + 1

digit2= 0
endwhile
stop

Note: if you know the "c" language and want to implement these codes on your own, the screenshots of code in the "c" language is attached for the first and last question, otherewise leave this portion.
