error C2679: binary '<<' : no operator found which takes a right-hand operand of type 'Rectangle' (or there is no acceptable conversion)

Question

im required to write a function to overload the ==operator to compare width, height and colour. i need to return 'Y' if its equal and 'N' if its not.

this is my code which i think its correct but keeps getting the error in the title.

i've done searches and nothing came close to comparing 3 data as most examples are for comparing 2 datas.

#include <iostream>
#include <string>
using namespace std;

class Rectangle
{
private:
    float width;
    float height;
    char colour;
public:
    Rectangle()
    {
     width=2;
     height=1;
     colour='Y';
    }
    ~Rectangle(){}
    float getWidth() { return width; }
    float getHeight() { return height; }
    char getColour() { return colour; }

    Rectangle(float newWidth, float newHeight, char newColour)
    {
     width = newWidth;
     height = newHeight;
     colour = newColour;
    }

    char operator== (const Rectangle& p1){

     if ((width==p1.width) && (height==p1.height) && (colour==p1.colour))
      return 'Y';
     else
      return 'N';
    }
};

int main(int argc, char* argv[])
{
    Rectangle rectA;
    Rectangle rectB(1,2,'R');
    Rectangle rectC(3,4,'B');
    cout << "width and height of rectangle A is := " << rectA.getWidth() << ", " << rectA.getHeight() << endl;
    cout << "Are B and C equal? Ans: " << rectB==rectC << endl;


    return 0;
}

Answer 1

Looks like you need some parentheses:

cout << "Are B and C equal? Ans: " << (rectB==rectC) << endl;

It's an operator precedence issue; the << is being applied to rectB before the == runs.

Answer 2

"<<" is higher precedence than "==". Put your comparison in parentheses:

cout << "Are B and C equal? Ans: " << (rectB == rectC) << endl;
