Hey folks. I'm hoping I can get some help here. I have to make this program to play the game paper, rock scissors. I am having a few issues with the program.

1.) I dont think i am using the rand() correctly
2.) After entering your choice for Paper Rock or Scissors it just ends the program.
3.) I cant figure out the correct way to display the win/loss/tie/percentage stats/and number of games played
4.) and lastly I am having a problem figuring out how to loop the program back to asking if you want to play the game.

Any help is appricated. Heres the code. Thanks in advance!

Run this in a debugger and single-step it through the code. You will soon find your problem. If you haven't yet used a debugger, it is time to learn!
