Simple C Calculator

A lightweight, command-line interface (CLI) calculator written in C. This program performs basic arithmetic operations through a simple menu-driven system.

---

🚀 Features

The calculator supports the following operations:

• Addition (+): Adds two floating-point numbers.
• Subtraction (-): Subtracts the second number from the first.
• Multiplication (*): Multiplies two floating-point numbers.
• Division (/): Divides the first number by the second.
• Error Handling: Includes a safety check to prevent division by zero.
• Continuous Execution: Runs in a loop until the user selects the exit option.

🛠️ Code Overview

The project is structured into modular functions for better readability and logic separation:

Core Functions

• float add(float a, float b): Returns the sum.
• float subtract(float a, float b): Returns the difference.
• float multiply(float a, float b): Returns the product.
• float divide(float a, float b): Handles division and checks for zero-divisor errors.

Implementation Details

• Input Handling: Uses scanf to capture user choices and numeric values.
• Control Flow: Utilizes a while(1) loop and a switch statement for navigation.
• Formatting: Results are displayed with two decimal places (%.2f) for precision.
