Write a program that reads two input files whose lines are ordered by a key data field.
Write a program that reads two input files whose lines are ordered by a key data field. Your program should merge these two files, writing an output file that contains all lines from both files ordered by the same key field. As an example, if two input files contain student names and grades for a particular class ordered by name, merge the information as shown below
You must read one line of a file at a time and either write it or the last line read from the other data file to the output file. A common merge algorithm is the following:
Read a line from each data file
While the end of both files has not been reached
If the line from file 1 is smaller than the line from file 2
Write the line from file 1 to the output file and read a new
line from file 1
Else
Write the line from file 2 to the output file and read a new line from file 2.
Write the remaining lines (if any) from file 1 to the output file.
Write the remaining lines (if any) from file 2 to the output file.
