Function Overloading Practice
Завдання
Swipe to start coding
Create program for a shape calculator that uses function overloading to calculate the area of different shapes (rectangle, circle, and triangle). These functions will have the same name but will be able to calculate area for different types of figures.
Your task is to create overloaded calculateArea() functions. All arguments must have double type:
- The first function must have two positional arguments,
lengthandwidth(the order of arguments must be the same!). - The second function must have one argument named
radius. - The third function must have three arguments,
a,bandc. These arguments represent the length of all sides of the triangle.

}
// Overloaded function to calculate area of a circle

}
// Overloaded function to calculate area of a triangle
double calculateArea(double a, double b, double c) {
double s = (a + b + c) / 2; // Calculate semi-perimeter
double area = sqrt(s * (s - a) * (s - b) * (s - c)); // Heron's formula
return area;
}
int main() {
// Calculate and display area for different shapes
std::cout << "Circle - Area: " << calculateArea(3) << std::endl;
std::cout << "Rectangle - Area: " << calculateArea(4, 6) << std::endl;
std::cout << "Triangle - Area: " << calculateArea(5, 4, 6) << std::endl;
