My program seems to always exit after reading one line.
Shouldn't it only halt when a line ends with an exclamation mark?
After reading a line, I check the last character using a switch.
When the character is a period, I print "*Nod*".
When the character is a question mark, I print "Quack!".
Wait, both get printed before the program exits?
I guess I forgot to add break; here and there...
I quacked the code!
