Which arithmetic operations are supported by the calculator program?

The calculator program typically supports the following basic arithmetic operations:

1. Addition: Adding two numbers.
2. Subtraction: Subtracting one number from another.
3. Multiplication: Multiplying two numbers.
4. Division: Dividing one number by another.

In a C++ program, for example, you might implement these operations using separate functions. Here's a simple outline:

#include <iostream>
using namespace std;

int add(int a, int b) {
    return a + b;
}

int subtract(int a, int b) {
    return a - b;
}

int multiply(int a, int b) {
    return a * b;
}

float divide(int a, int b) {
    if (b != 0) {
        return static_cast<float>(a) / b; // Typecasting to float for accurate division
    } else {
        cout << "Error: Division by zero!" << endl;
        return 0; // Handle division by zero
    }
}

This program allows users to perform addition, subtraction, multiplication, and division of two integers. If you need more details or examples, let me know!
