In this assignment, the task is to develop a simple guessing game program that involves interacting with files, generating random numbers, and implementing game logic. The program should read a range of numbers from a text file, generate a secret number within that range, and then allow a user to guess the number, providing feedback on whether the guesses are too high or too low. Additionally, the program should enable replay functionality, and expand to a version where the computer attempts to guess the user's secret number efficiently. The implementation relies on multiple custom structs and functions, including String, ReadFile, Keyboard, and Random, with specific method signatures provided in header files. The program should structure its logic into modular methods for clarity and maintainability. Batch files are used for compiling and executing the code efficiently, with modifications possible for optimization. The core functions to be completed include range reading, secret number generation, guess validation, guess processing, game loop control, and AI-based guessing.

Paper For Above instruction

The development of a simple yet robust guessing game in C++ serves as an excellent project to demonstrate fundamental programming principles such as file handling, random number generation, modular design, and user interaction. This assignment emphasizes the importance of breaking down complex tasks into manageable functions, thereby increasing code clarity, reusability, and maintainability. The game involves reading a specified range from an external file, generating a random secret number within that range, and prompting the user to make guesses. Feedback is provided on whether each guess is too high or too low until the correct number is guessed, at which point the total number of attempts is displayed. The game then offers the option to replay, encapsulating a loop that maintains user engagement and improves code modularity.

One of the core components of this implementation is the use of custom structs such as String, ReadFile, Keyboard, and Random, each accompanied by defined method signatures that facilitate input/output operations and random number generation. The String struct manages dynamic strings, enabling efficient string manipulation through functions like createString, compare, substr, and destroyString. ReadFile handles reading input from external files, ensuring the game can dynamically adapt to different ranges, while Keyboard manages user prompts for guesses, incorporating input validation and error handling. Random encapsulates the logic for pseudorandom number generation, initialized with a seed value based on the current time to ensure proper randomness across game sessions.

The primary functions to be developed include getRange(), getSecret(), getGuess(), processGuess(), and play(), each with specific roles. The getRange() function prompts the user for a filename, reads the two integers that define the range, and manages memory allocation and deallocation for the integer array. getSecret() employs the Random struct to generate a number within the specified range, serving as the secret for each game session. The getGuess() function prompts the user for guesses, validating that the guesses are within the specified range. processGuess() compares the user’s guess against the secret number, returning an enum to indicate if it’s correct, too high, or too low, facilitating clear game logic flow. The play() function orchestrates the game loop, counting the number of guesses until the secret is guessed, and managing user replay requests.

Additionally, the assignment extends into artificial intelligence by implementing a driver that allows the computer to guess the user’s secret number. This involves developing an efficient guessing strategy, such as binary search, to minimize the number of guesses. The driver, potentially named ComputerGuessDriver.cpp, leverages the existing functions for guesses but applies a systematic approach to narrow down the possible number range after each attempt, assessing whether the guess is too high or low, refining the search accordingly. The goal is to identify the secret number using the fewest guesses, and analyzing the maximum number of guesses needed for certain secret numbers informs the effectiveness of the guessing strategy.

Batch files such as build.bat are used to compile and link the code seamlessly, with options for customizing the compilation process by commenting out unnecessary files. The build process ensures smooth development cycles and easy testing of different program components. Overall, this assignment encompasses key programming skills applicable across various software development domains, fostering good practices in modular design, file I/O, randomization, conditional logic, and algorithm optimization. Through completing this guessing game, students will gain a deeper understanding of how to structure interactive applications and implement algorithms that involve decision-making based on user inputs and system-generated data.
