}My assignment:
The user inputs either an 'h' for heads or 't' for tails for eight tosses,
then the program will print out the total number and percentages of head and tails. I am supposed to use an called increment operator to count, but I looked online everywhere and couldn't find out how to use it. I think I am doing this right, but I am not sure. We are supposed to use SavitchIn.java if you are wondering.
