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.
