Write a program that compares two files and prints information about the differences between them. For example, consider a file data1.txt with the following contents:
This file has a great deal of text in it which needs to be processed.

Consider another file data2.txt that exists with the following contents:
This file has a grate deal of
text in it which needs to
bee procesed.
A dialogue with the user running your program might look like the following:
Enter a first file name: data1.txt
Enter a second file name: data2.txt
Differences found:
Line 1:
< This file has a great deal of
> This file has a grate deal of
Line 4:
< be processed.
> bee procesed.
