Question

Please I need help debugging this code thanks.

// The two senior class homerooms at Littleville High School
// are having a fundraising drive for the prom. Each time a student
// solicits a contribution, a record is created with the
// student's name and the value. Two files have been created for
// Homeroom A and Homeroom B. Each file is sorted in contribution
// value order from highest to lowest. This program merges the two files.

ANSWER:

CODE:

start

      Declarations

              string roomAName

              num roomAValue

              string roomBName

              num roomBValue

              string bothFilesDone = "N"

              num HIGH_VALUE = 999999

              InputFile roomAFile

              InputFile roomBFile

              InputFile mergedFile

      getReady()

      while bothFilesDone = "N"

            detailLoop()

      endwhile

      allDone()

stop

getReady()

      open roomAFile "roomAFile.dat"

      open roomBFile "roomBFile.dat"

      open mergedFile "mergedFile.dat"

      readA()

      readB()

      checkBoth()

return

readA()

      input roomAName, roomAValue from roomAFile

      if eof then

            roomAValue = HIGH_VALUE

      endif

return

readB()

      input roomBName, roomBValue from roomBFile

      if eof then

            roomBValue = HIGH_VALUE

      endif

return

checkBoth()

      if roomAValue = HIGH_VALUE AND roomBValue = HIGH_VALUE then

            bothFilesDone = "Y"

      endif

return

detailLoop()

      if roomAValue > roomBValue then   

            output roomBName, roomBValue to mergedFile /* It should be output roomAName, roomAValue to mergedFile */

            readA()

      else

            output roomAName, roomAValue to mergedFile /* it should be output roomBName, roomBValue to mergedFile */

            readB()

      endif

/* Here checkBoth() method should be called */

return

allDone()

      close roomAFile

      close roomBFile

      close mergeFile

return

Explanation:

1. The 2nd line in detailLoop() method should be output roomAName, roomAValue from roomAFilebecause the introductory comment of debbuging 2 states that Each file is sorted in contribution value order from highest to lowest. in if (roomAValue> roomBValue) is true means roomAFile values should be copied to mergerFile.

2. The 5th line in detailsLoop() method should be output roomBName, roomBValue from roomBFilebeacuse as stated above if if condition is false then roomBFile values should be copied to mergeFile.

3. After endif in detailLoop() function there should be checkBoth() function because it will check for the both files are at EOF or not. If it is true then the "Y" is assigned to bothFileDone variable and then while(bothFileDone="N") will be failed so that we can exit from the loop. otherwise it will turn to infinite loop.
