Slot Machine - Functional Programming in C++

This project is a command-line slot machine game developed in C++ with real-time animation. It is designed according to functional programming principles, using recursion instead of loops. The game displays spinning slot symbols in the terminal and ends with a message indicating whether you have won or lost.

Features

• Real-time slot machine animation for an engaging terminal experience.
• Functional programming principles are applied, using recursive structures to avoid loops.
• Enjoyable user experience with emoji symbols.
• Written with a Haskell-inspired approach in C++.

Technologies Used

• C++: The primary programming language.
• Functional Programming Principles: Completely recursive structures are used to eliminate loops.
• ANSI Emojis: Symbols displayed in the terminal for a visual experience.

Installation and Execution

Requirements

• C++17 or newer.
• A C++ compiler (e.g., g++ or clang++).

Compile and Run

You can compile and run the project with the following commands:

mkdir build && cd build && cmake .. && make
./slot

Code Overview

Functional Programming Structure

This project is built to adhere to functional programming paradigms. All iterations are achieved with recursive functions instead of loops:

• animate_spin: Recursively runs the slot machine animation until the specified time is reached, creating a spinning slot effect in the terminal.
• print_symbols: Displays slot symbols in the terminal without using a loop, ensuring each symbol is printed recursively.
• spin_slot: Generates random symbols for each slot row, operating as a pure function independent of outside effects.

Functions

• get_random_symbol: Returns a random slot symbol.
• spin_slot: Generates the desired number of random symbols to create a slot row.
• animate_spin: Recursively runs the slot animation.
• print_symbols: Prints symbols to the terminal one by one recursively.
• play_game: Starts the game, runs the animation, and displays the result.

Sample Run

For example, setting the number of slots to 4, you will see the spinning symbols in the terminal, followed by a message indicating if you've won or lost:
