//Add the function prototypes need for the functions below.
double getLength(double);
double getArea(double);
double getWidth(double);
int main()
{
double length, // The rectangle's length
width, // The rectangle's width
area; // The rectangle's area

// Get the rectangle's length.
getLength();

// Get the rectangle's width.
getWidth();

// Get the rectangle's area.
getArea();

// Display the rectangle's data.
displayData();
system ("pause");
return 0;
}
