The Graphing Calculator allows users to input mathematical expressions and generate corresponding graphs. With essential features like zooming, scrolling, and a history bar, it provides a smooth experience for exploring mathematical concepts. Additionally, the application stores previous functions in a text file for easy access and recall across sessions.

• Graph Visualization: Input mathematical functions and visualize their graphs.
• Zoom and Scroll: Zoom in/out and scroll around the graph for detailed analysis.
• History Bar: Easily access and select previous functions from the history bar.
• Function Persistence: Store functions in a text file for easy retrieval across sessions.

Our graphing calculator leverages a variety of technologies to provide its functionality:

• RPN (Reverse Polish Notation): Used for parsing mathematical expressions efficiently.
• Shunting Yard Algorithm: Converts infix expressions to postfix notation, facilitating evaluation.
• SFML (Simple and Fast Multimedia Library): Provides the graphical user interface for drawing graphs.
• Arrays, Linked Lists, Stack, Queue: Data structures used for managing history and processing expressions.
• Tokenizer: Splits input expressions into tokens for parsing and evaluation.
