The document contains C++ code for a simple blackjack game, including functions for card handling, player actions, and scoring. It allows players to choose difficulty levels and play multiple rounds with betting mechanics based on winning conditions. The program handles both player and dealer actions, calculates scores, and determines win/loss outcomes.
