Rectangle Area Homework

[djr1599]

For my homework assignment, I'm supposed to create a program that asks for length and width of a rectangle, calculate the area then display it using 4 different functions which are shown in my code. I have no errors when I compile and when I run it, it seems to work until I get to the final part. The area keeps displaying as some long decimal number.

  #include <iostream>
using namespace std;

double getLength();
double getWidth();
double getArea(double length, double width);
void displayData(double length, double width, double area);

int main()
{
	double length,width,area;
	
	length=getLength();
	width=getWidth();
	getArea(length,width);
	displayData(length,width,area);
}

double getLength()
{
	double length;
	cout<<"Enter the length of the rectangle: ";
	cin>>length;
	return length;
}
double getWidth()
{
	double width;
	cout<<"Enter the width of the rectangle: ";
	cin>>width;
	return width;
}
double getArea(double length,double width)
{
	double area;
	area=length*width;
	return area;
}
void displayData(double length, double width, double area)
{
	cout<<"The length is: "<<length<<endl;
	cout<<"The width is: "<<width<<endl;
	cout<<"The area is: "<<area<<endl;
}

What does line 15 do?

Yes, see line 15 and what is that missing for line 16. Read the run-time error carefully. :)
