Assume that the file myData.txt exists and contains only one line that says: "Hello World!". When users run the following program: a) what do they see on their screen? b) what do they see in the file myData.txt? c) what lines would you change in the program and what would the changes be if you want the output file to be "myOtherData.txt" and you also wanted to ensure that your program-generated output stream was placed after the end of whatever was in the text file? d) what additional code would you insert in the program in the code if you wanted to first check on the existence of the file "myData.txt" and then if it did not exist print out a message to the user about the file not existing and subsequently quitting the program, and show where exactly this would go in the existing code?
