Problem: Write a program that prompts for the names of a source file to read and a target file to write, and copy the content of the source file to the target file, but with all empty lines removed, then output the number of empty lines removed.

Source file name: string$\_$doc.txt

Target file name: string$\_$doc$\_$nonempty.txt

Lines removed: $16$

Answer: Copy your code in the space given below and insert screenshots of your program output for the following two scenarios:

$$ Use the attached file P$1\_$v$1.$txt as the source file to read. Use P$1\_$v$1\_$nonempty.txt as the target file name.

$$ Use the attached file P$1\_$v$2.$txt as the source file to read. Use P$1\_$v$2\_$nonempty.txt as the target file name.
