Introduction

The task is to implement a Black Jack program for two players. The game is based on a 52-card deck

where each card face has some point count. Aces may be counted as 11 or as 1, whichever is better

for the player. The goal is to get more points than the enemy but definitely not more than 21.

The program stores its deck as array of C++ structures, shuffles the deck and then plays 5 rounds.

For each card, the current point count is shown. After each round the winning player and the current

score is shown.

Coding approach

I tried to make most constants used in the program (for example, the maximum allowable number of

points, 21) to be C++ constants. Also, I created several functions to make the program more modular.

I show star (*) after a score if an ace was counted as 1.

Conclusion

The program was relatively interesting to write because it deals with a game and uses random

numbers. It was not too hard to write but also not too simple. There are some additions possible to

make the game more interesting (manual choice whether to take the next card, for example).
