C++ Calculator

A simple command-line calculator built using C++ that performs basic arithmetic operations like addition, subtraction, multiplication, and division.

📌 Features ➕ Addition ➖ Subtraction ✖️ Multiplication ➗ Division 🧠 User-friendly menu-driven interface ⚠️ Handles division by zero errors 🛠️ Technologies Used Language: C++ Compiler: g++ / any C++ compatible compiler Platform: Cross-platform (Windows, Linux, macOS) 📂 Project Structure calculator/ │── main.cpp # Main source code │── README.md # Project documentation 🚀 Getting Started

1. Clone the Repository git clone https://github.com/your-username/cpp-calculator.git cd cpp-calculator
2. Compile the Code g++ main.cpp -o calculator
3. Run the Program ./calculator 💻 Usage Run the program Select an operation from the menu Enter two numbers View the result Example Select operation:
4. Add
5. Subtract
6. Multiply
7. Divide

Enter choice: 1 Enter two numbers: 5 3

Result: 8 ⚠️ Error Handling Division by zero is not allowed Invalid menu choices are handled gracefully 📸 Sample Code Snippet #include using namespace std;

int main() { int choice; double a, b;

cout << "1. Add\n2. Subtract\n3. Multiply\n4. Divide\n";
cin >> choice;

cout << "Enter two numbers: ";
cin >> a >> b;

switch(choice) {
    case 1: cout << "Result: " << a + b; break;
    case 2: cout << "Result: " << a - b; break;
    case 3: cout << "Result: " << a * b; break;
    case 4:
        if (b != 0)
            cout << "Result: " << a / b;
        else
            cout << "Error! Division by zero.";
        break;
    default:
        cout << "Invalid choice";
}

return 0;
