Fixing an error involving calling on a Class

[patrickweiss52]

Hey guys,

This is my first time posting here so hopefully I'll be understandable. I'm taking CS 1410, which is C++. Here are the instructions for the lab.

-It should create an object of your rectangle class.
-Use the parameterized constructor and pass in the values of 4 and 7 as the height and width.
-Using getHeight and getWidth, display the size of the rectangle represented by your Rectangle object.
-Using the getArea function, display the area of the rectangle object.

Here is my code:
MyRectangle.h

  #include "MyRectangle.h" //we #include the header file for the MyRectangle Class
#include <iostream>
#include<string>



using namespace std;
MyRectangle rectangle(int,int); //make an instance of the myRectangle class on the stack

// Main is the window the the calculations of the program
int main()
{
	const int WIDTH = 4, HEIGHT = 7;
	rectangle(WIDTH, HEIGHT);//use the paramaterized constructor to populate the object.
	
	cout << "\nThe size of the retangle is\t" << rectangle.getWidth() << "by\t" << rectangle.getHeight() << endl;
	cout << "\nThe area of the retangle is\t" << rectangle.getArea();


	system("PAUSE");
	return 0;
}

MyRectangle.cpp

#include "MyRectangle.h"


MyRectangle::MyRectangle()
{
	width = 0, height = 0;
}


MyRectangle::MyRectangle(int a,int b)
{
	width = a, height = b;
}


int MyRectangle::getHeight(void)
{
	return height;
}

int MyRectangle::getWidth(void)
{
	return width;
}

int MyRectangle::getArea(void)
{
	 return width*height;
}

Driver.cpp

#include "MyRectangle.h" //we #include the header file for the MyRectangle Class
#include <iostream>
#include<string>

using namespace std;
MyRectangle rectangle(int,int); //make an instance of the myRectangle class on the stack

int main()// Main is the window the the calculations of the program
{
	const int WIDTH = 4, HEIGHT = 7;
	rectangle(WIDTH, HEIGHT);//use the paramaterized constructor to populate the object.
	
	cout << "\nThe size of the retangle is\t" << rectangle.getWidth() << "by\t" << rectangle.getHeight() << endl;
	cout << "\nThe area of the retangle is\t" << rectangle.getArea();

	system("PAUSE");
	return 0;
}

It won't compile. I have squiggly red lines of death underneath "rectangle" when I'm calling the functions in my cout lines: rectangle.getWidth(), rectangle.getHeight(), and rectangle.getArea().

The error says they must have a class type if I hover my mouse cursor over them and in the error list this is stated:
Error 2 error C2228: left of '.getWidth' must have class/struct/union

MyRectangle rectangle(int, int) it looks like a function to me
Try to put it in main with its parameters

Same error.

Here is current iteration:
Driver.cpp

#include "MyRectangle.h" //we #include the header file for the MyRectangle Class
#include <iostream>
#include<string>

using namespace std;
 

int main()// Main is the window the the calculations of the program
{
	MyRectangle rectangle(int,int);//make an instance of the myRectangle class on the stack

	const int WIDTH = 4, HEIGHT = 7;
	
	rectangle(WIDTH, HEIGHT);

	cout << "\nThe size of the retangle is\t" << rectangle.getWidth() << "by\t" << rectangle.getHeight() << endl;
	cout << "\nThe area of the retangle is\t" << rectangle.getArea();

	system("PAUSE");
	return 0;
}

I mean MyRectangle retangle(WIDTH,HEIGHT);

[patrickweiss52]

You are right LendraDwi. It compiles that way. I couldn't figure out how to pass parameters correctly. In the information the teacher gave me there is no example of this only of calling on the default constructor.

Thank you so much for the fast response and the help!
