i have so many reasons to hate c++

default constructor syntax

#include <iostream>
using namespace std;

#include <iostream>
using namespace std;

class Rectangle {
    int width, height;
  public:
    Rectangle (int,int);
    Rectangle();
    int area() {return width*height;}
};

Rectangle::Rectangle (int x, int y) {
  width = x;
  height = y;
}

Rectangle::Rectangle(){
    width = 5;
    height = 10;
}

int main () {
  Rectangle rect; //this is okay
  //Rectangle rect(); //this is not
  cout << "area: " << rect.area() << endl;
  return 0;
}
