Programming Assignment7 Poker 5-Card Drawassignedwednesday April

Write a program that allows a user to play 5-Card-Draw Poker against the computer. Start with the provided example code from Deitel & Deitel. Complete the following functions: (a) Modify the card dealing function to deal a five-card poker hand; (b) Write a function to determine if the hand contains a pair; (c) Write a function to determine if the hand contains two pairs; (d) Write a function to determine if the hand contains three of a kind; (e) Write a function to determine if the hand contains four of a kind; (f) Write a function to determine if the hand contains a flush; (g) Write a function to determine if the hand contains a straight. Use these functions to deal two hands, evaluate, and compare them. Simulate the dealer's hand, allowing automatic drawing based on hand quality. Enable the player to select which cards to replace, evaluate the hands, and determine the winner. Play 10 games against the computer and refine your program as needed. Submit your complete project with one header (.h) file, two C (.c) source files, and ensure it builds correctly.

Paper For Above instruction

The development of a comprehensive 5-Card Draw Poker game in C encapsulates fundamental programming concepts such as arrays, pointers, struct manipulation, function design, and control flow—all essential skills for software engineers. This project not only assesses the ability to implement these concepts but also emphasizes creating an interactive and user-friendly gaming experience. The following discussion elaborates on the key stages involved in designing and executing this project, highlighting critical programming techniques and best practices.

Understanding the Game and Its Rules

At the core of developing a poker game lies a clear understanding of the game rules and logic. 5-Card Draw Poker involves dealing five random cards to each player, allowing the contender to replace any subset of cards, and then evaluating the hands according to standard poker hierarchies. Recognizing hand ranks—pair, two pairs, three of a kind, straight, flush, four of a kind—is fundamental for subsequent evaluation functions. Additionally, managing the game flow, including dealing, replacing cards, and comparing scores, requires a structured approach to program flow control.

Array and Data Structures Utilization

Arrays are vital for holding the player's and dealer's hands, which are collections of cards represented via structures. A typical approach is to define a Card structure encompassing attributes such as face value and suit. A common technique involves creating a 2D array or array of structures to hold multiple hands, allowing ordered access and manipulations such as dealing and evaluating hands. Arrays of pointers to strings can be used for mapping numeric card values and suits to human-readable forms, thus facilitating user output and input parsing.

Pointer and Memory Management

Implementing pointer arrays and dynamic memory allocation allows flexible data management. The use of pointers to strings for suits and face values simplifies the representation of cards. Function parameters often utilize pointers for in-place modification—such as swapping a card during replacement or updating hand states—beneficial for efficiency and program clarity. Proper memory management, including dynamic allocation where necessary and freeing resources, ensures robustness, especially in more complex implementations involving file I/O for game statistics or multi-round play.

Function Design and Modular Programming

Modular functions encapsulate common poker evaluations: detecting pairs, two pairs, three of a kind, four of a kind, straights, and flushes. For example, implementing a function like isPair() involves iterating through the hand to check for duplicate face values, which highlights the utility of nested loops and array traversal. Similarly, determining a straight requires sorting hand values and verifying consecutive sequence, demonstrating control flow management. Functions should have clear input and output parameters, facilitating code readability and debugging.

Algorithmic Approach and Loop Usage

Repetition structures like for or while loops are central to evaluating hands and managing game play. For instance, dealing cards involves nested loops to assign random cards while avoiding duplicates, which may involve checking previously dealt cards using arrays. During the replacement phase, the program prompts user input, modifies the hand array, and reevaluates the hand. Loop constructs also manage the game sequence—playing multiple rounds, handling user choices, and resetting variables between games.

Poker Hand Evaluation and Comparison Logic

Assessing hand strength involves implementing a hierarchy of poker hands—starting from high card to four of a kind. Creating a function that assigns a numerical ranking or category to each hand simplifies comparison. For example, a hand with a four of a kind might be assigned a higher rank than a flush. Tie-breaking mechanisms, such as comparing highest cards within the same rank, are essential for determining a winner accurately. These comparisons require careful design of a compareHands() function that returns the better of two evaluated hands.

Input and Output Handling

User interaction scenarios include selecting cards to replace, viewing dealt hands, and deciding whether to continue playing. Handling user input robustly involves validating entries—such as ensuring card selections are within valid ranges—and providing clear prompts. Outputting theHands in a human-readable format benefits from mapping integers to string representations via string arrays, which enhances usability and clarity.

Project Organization and Code Structure

Effective code organization involves dividing the program into multiple files:

- A header file (.h) defining structures, constants, and function prototypes.

- Two source files (.c): one handling game logic and evaluation, another managing user interface and game flow.

- Properly encapsulating code promotes maintainability, testing, and reusability.

Ensuring that the project compiles without errors and adheres to coding standards—such as meaningful comments, consistent indentation—is critical for maximizing scores.

Refinement, Testing, and Enhancements

Once the core game mechanics are functional, extensive testing ensures accuracy. Testing involves simulating multiple game scenarios, verifying hand evaluations, and making refinements. Enhancements could include adding features such as score tracking, graphical displays, or extended betting mechanics, but core functionality must meet assignment requirements.

Conclusion

Developing a 5-Card Draw Poker game in C demonstrates proficiency in array manipulation, pointer arithmetic, struct management, and algorithm design. It consolidates essential programming skills like modularity, control flow, and user interaction handling, providing a solid foundation for more advanced software projects. Adhering to assignment guidelines and rigorous testing ensures a complete, functional, and well-structured program that offers an engaging user experience while showcasing core programming competencies.
