**We are using input.txt as our file. This is not an ideal

**see the changes. We can manually write in input.txt and
**we can also use the program to write to the file. 
**Then we can read what we wrote using our program.
**
**Your assignment for this quiz**
**Change the contents of the file called input.txt
**Change the ifstream and ofstream to fstream
