SimpleMathREPL

A simple command-line math evaluator written in C. This program supports basic arithmetic operations, operator precedence, parentheses, and variables. It allows you to evaluate mathematical expressions interactively.

Features

• Basic Arithmetic: Supports +, -, *, and / operations.
• Operator Precedence: Follows standard operator precedence (multiplication and division are evaluated before addition and subtraction).
• Parentheses: Supports parentheses () for grouping expressions and controlling the evaluation order.
• Variables: You can store results in variables (single-letter variables, a-z), and use them in subsequent expressions.

Usage

1. Run the Program: Simply compile and run the program. It will prompt you for input.

   make
   ./smrepl

2. Basic Operations: You can enter expressions like:

   $ 3 + 5 * 2
   = 13
   $ (3 + 5) * 2
   = 16

3. Variables:

   You can assign values to variables using the > operator. Variables are single letters from a to z.

   Example:

   $ 1 + 2 > x  # Assigns the result of the expression to variable 'x'
   = 3
   $ 3 + 5 > y
   = 8
   $ x + y
   = 11

4. Exit: To exit the program, use Ctrl+D or Ctrl+Z (depending on your operating system).
