Interactive C++ Terminal Calculator 🧮

A lightweight, robust command-line calculator built with C++. This project focuses on clean user input handling and a sleek terminal interface.

✨ Key Features

• Smart UI: Uses ANSI escape codes (\033[A\r) to overwrite input lines, keeping the terminal display clean and professional.
• Robust Input Handling: Prevents crashes from invalid characters (like letters) using std::cin.clear() and std::numeric_limits.
• Arithmetic Operations: Supports Addition (+), Subtraction (-), Multiplication (*), and Division (/).
• Safety First: Includes explicit checks for division-by-zero errors.
• Tutorial Mode: Built-in guidance to help new users understand the input format.

🚀 Getting Started

Prerequisites

• A C++ compiler (GCC, Clang, or MSVC).
• A terminal that supports ANSI escape sequences (VS Code Terminal, Linux/Mac Terminal).

Compilation & Running

1. Clone the repository: bash git clone https://github.com

2. Compile the source code: bash g++ -o calculator main.cpp

3. Run the application: bash ./calculator

🛠️ Implementation Details The calculator uses a while(true) loop to maintain a continuous session. It validates input using a structured check: cpp if (!(cin >> num1 >> op >> num2)) { // Error recovery logic } Use code with caution.

This ensures the program remains stable even when receiving unexpected input formats. 📸 Preview text Calculation: 10 + 5 = 15 Calculation: 20 / 4 = 5 Error: Division by zero! Use code with caution.
