Confused on this topic: I/O streams. I will add the description of the lab, and I will copy the data of the .txt it wants to use. If you could also comment in the code what is what, I would really appreciate that. It will help me study and understand it. Thank you.

message.txt

Today Bill Smith ate 3 apples and 2 pears. 

Write a complete C++ program to read the file message.txt, character by character using the get member function. See page 338 for the get member function See page 356 for end-of-file character processing If the character is not a Lower Case letter, write the character to a file "upper.txt". If the character is a Lower Case letter, write the Upper Case version of the character to the file upper.txt Your output file should look like: TH ATE 3 APPLES AND 2 PEARS
