// Area Calculator using Function Overloading
#include <iostream>
// For PI, you might use #define _USE_MATH_DEFINES and #include <cmath>
// but for simplicity and portability, we'll define it manually.
const double PI = 3.14159;

// Function to calculate the area of a circle
double calculateArea(double radius) {
    return PI * radius * radius;
}

int main() {
    // Step 1: Calculate area of a circle
    double radius = 5.0;
    std::cout << "Area of Circle with radius " << radius << ": " << calculateArea(radius) << std::endl;
    // ... other calculations will follow here
    return 0;
