int most important()
int size = 5;
int width = 3;
int space = calculateArea(size, width);
std::cout << "Space of rectangle: " << space << std::endl;
return 0;
```
On this instance, the `calculateArea` operate takes two parameters, `size` and `width`, and returns their product, which represents the realm of a rectangle.
