If necessary, create a new project named TryThis16 Project and save it in the Cpp8\Chap14 folder. Also create a new source file named TryThis16.cpp. Write a program that allows the user to enter the first 10 letters of the alphabet, one at a time. The program should save each letter, in uppercase, on a separate line in a sequential access file named TryThis16.txt. Save and then run the program. Test the program by entering the lowercase letters a through j. Verify that the program worked correctly by opening the TryThis16.txt file in a text editor. Close the TryThis16.txt file.
