This project is a simple expression calculator implemented in C. It provides functionalities to convert infix expressions to postfix notation and evaluate the resulting postfix expressions.

The project directory contains the following files:

• cal.exe: Executable file for the expression calculator.
• expression-calculator-onefile.c: Main source file containing the implementation of the expression calculator.
• expression_calculator.c: Source file containing functions for converting infix expressions to postfix notation and evaluating postfix expressions.
• list.h: Header file containing the implementation of a linked list data structure.
• util.h: Header file containing utility functions and definitions used in the project.

To run the game, follow these steps:

git clone https://www.github.com/h4jack/cal.git ./Expressioin-Calculator

cd Expressioin-Calculator

./cal.exe

To use the expression calculator, you can compile the source files using a C compiler and then run the executable. Here's how to use it:

• Compile the source files:

gcc expression-calculator-onefile.c expression_calculator.c -o cal.exe

• Run the executable:

./cal.exe

• You will be prompted to enter an infix expression. You can also pass the expression as command-line arguments, e.g.:

cal ./cal.exe "10*(-13+17)/1.5-17"

• The calculator will convert the infix expression to postfix notation, evaluate the postfix expression, and display the result.

For detailed documentation of the code and its functionalities, refer to the Documentation.md file.

The expression calculator project provides the following features:

• Convert infix expressions to postfix notation.
• Supports arithmetic operators: addition (+), subtraction (-), multiplication (*), division (/), modulus (%), and exponentiation (^).
• Handles parentheses to determine the order of operations.

• Evaluate postfix expressions using a stack-based approach.
• Support for basic arithmetic operations and precedence rules.

• Detects and handles various types of errors in input expressions.
• Error messages are displayed for informative purposes, including:
  • Invalid expressions.
  • Division by zero.
  • Unmatched parentheses.

• Accepts infix expressions as command-line arguments.
• Provides a user-friendly interface for entering infix expressions if no arguments are provided.
• Optional verbose mode (-v or -V) for displaying the input infix expression and the resulting postfix expression.

• Organized into multiple source files for clarity and maintainability:
  • expression-calculator-onefile.c: Main entry point and command-line argument processing.
  • expression_calculator.c: Core functionality for expression conversion and evaluation.
  • list.h: Implementation of a linked list data structure.
  • util.h: Utility functions and definitions used throughout the project.

• Written in C for portability across different platforms.
• Simple compilation and execution process for ease of use.
