Project 1 is to develop a program that will
open a text file of at least 13 characters and read
its contents and display it to the screen. However,
convert all letters to the opposite case.
Remember that I do not have the same files that you have
so you will have to allow the user to specify the filename.
The results is to be in the form of
Hello
becomes
hELLO
The output of your program will look like this:
C:\My Documents\cmsc211\Spring00\proj1>proj2
Enter the name of the file: gary.dat
hELLO, wORLD!
