Rock, Paper, Scissors & Yahtzee

/*----------------------------------------------------------------------------------------
Programmer : Jesse Moore
Date: October 21, 2020
Description : This program will be a menu driven program. It will give the user 3 options.
* For option 1, the user will be able to simulate a match of rock, paper, scissors.
* For option 2, the user will be able to simulate a game of Yahtzee.
* For option 3, the program will end.
