#include #include #include #include #include using namespace std; /* Code By: Zeke Williams Date: September 10, 2017 Instructions: JUST HIT RUN! OPTIONAL: you can change to texas hold em in main() Version: 1.05 Updates: 1.05 - Commented EVERYTHING for learning purposes 1.04 - Re-Wrote most of the code to fix the things I did in v1.03. I Also added an opponent's hand for both game modes! So now you aren't just playing for a high score. Planned additions: More types of card games that would work for this. Description: This is a random chance card game. You will be dealt a traditional poker hand of five cards or two, depending on game mode. See if you can get a good hand, and let me know what you get in the comments!
