Need assistance with this simple program

hhjkkh10 (20)
This is my first ever OO program so please don't judge me lol. This program is meant to print out the area of a rectangle and triangle with the same width and height. I feel that my classes are correct, but i have no idea how to use them in the main. Thanks for the help in advance :)
Here is the task im trying to complete,
Write a program with a mother class and an inherited daugther class.Both of them should have a method void display ()that prints a message (different for mother and daugther).In the main define a daughter and call the display() method on it.

My code so far:

// OOP exercises.cpp : Defines the entry point for the console application.

#include "stdafx.h"
#include <iostream>
using namespace std;

class shape {
	public:
		shape(int height, int width) {
			height = 5;
			width = 4;
		}
};

class rectangle {
	public:
		int area(int height, int width) {
		int area = height * width;
		cout << area << endl;
		}
};

class triangle {
	public:
		int area(int height, int width) {
		int area = height * width / 2;
		cout << area << endl;
		}
};







int main()
{
	
	triangle obj;
	rectangle myObj;



    return 0;
}

Your classes aren't entirely correct. Better would be:

#include <iostream>
class Shape
{
private:
    int w, h;
public:
private:
    Shape(int width, int height)
    {
        w = width;
        h = height;
    }
};

class Rectangle
{
public:
    Rectangle(int width, int height) : Shape(width, height)
    {
    }
    int area() 
    {
        return width * height;
    }
};
/*Do Triangle class in a similar way, only change the formula for the area*/

int main()
{
    Rectangle rect(5, 4);
    std::cout << rect.area();
}
