Task 20 Merging Data

1. This is a free design task.
2. Merge two sorted files (file1.dat and file2.dat) into one single sorted file (merged.dat).
3. Possible algorithms are as follows :
   • Copy two given files into the new file (merged.dat) and then sort the new file using any one of the sorting algorithms.
   • Compare the smallest elements of the files and copy the smaller of them into the new file (merged.dat). Repeat this until all elements of both files are used up.
4. The file structures of two given files are as follows :

   	file1.dat		file2.dat		Description
   	4215 Chan Tai Man 70 80 100 4227 Poon Bo Bo 82 80 80 4300 Cheung Do Do 50 70 90		4100 Hoi Sum 60 80 68 4230 Ko Hing 90 80 80		Admission Number Student's Name 3 Tests' Scores Admission Number Student's Name 3 Tests' Scores Admission Number Student's Name 3 Tests' Scores

   	merged.dat		Description
   	4100 Hoi Sum 60 80 68 4215 Chan Tai Man 70 80 100 4227 Poon Bo Bo 82 80 80 4230 Ko Hing 90 80 80 4300 Cheung Do Do 50 70 90		Admission Number Student's Name 3 Tests' Scores Admission Number Student's Name 3 Tests' Scores

5. After coding, save your file as t20.pas at the drive S:\www\0507cit\programming\.
6. Execute your program and fix any problem occurred.
