The issue is in the picture: When I input the the name of the file after choosing option (e) in the main menu, I enter the file name and purposefully enter it wrong (I enter hello.txt). The code then brings me back to the main menu where I press option (e) again. I then enter the correct name of the file (which is letters.txt) and the program continues. The program then asks me to input the name of the new file, and then I put new.txt, but the problem begins here. The program then asks me again to input the name of the new file (but it should only do it once).
