Thread: I need help with making a rectangle using a class!

Hey so I'm having trouble making this work. I do not know how to fix this code and I need some help!

Code:

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

class Rectangle {
    int width, height;
  public:
    void set_values (int,int);
    int area() {
       int answer;
      
       return answer;
    }
    Rectangle(int w, int h) {  // parameterized constructor
  
    }
};

void Rectangle::set_values (int x, int y) {
  
}

int main () {  

  Rectangle rect1(5,6);
  cout << "area: " << rect1.area() << endl;

  Rectangle rect2;
  rect2.set_values (3,4);
  cout << "area: " << rect2.area() << endl;
  return 0;
}
