Chapter 9, Problem 51CRP

Explanation of Solution

Modified algorithm:

The modified algorithm for “MergeFiles” function is given below:

def MergeFiles(InputFileA , InputFileB , OutputFile ):

If (both input files at EOF):

Stop, with OutputFile empty.

If(InputFileA is not at EOF):

Declare its first record to be its current record.

If(InputFileB is not at EOF):

Declare its first record to be its current record.

If (record of InputFileA and record of InputFileB has same key value)

Then Display only one value

Continue until both input files at EOF.

Algorithm Explanation:

• The given code is used to display the only one value in output file if both files contains the same key value records...
