No matching function to call

[Jojestic]

I'm having a problem with an assignment. I'm using a class that stores a point on a Cartesian plane, and deriving a class from it called circletype. Circletype has an additional member for the radius and a function to find the area.

My problem is with the constructor. The error is
point.cpp In constructor `circletype::ci rcletype(double , double, float)':
no matching function to point:point
candidates are: point:point (const point&)
point point(double, double)

The constructor for point is

point::point(double initial_x, double initial_y)
    {
        x = initial_x;   // Constructor sets the point to a given position.
        y = initial_y;
    }

The constructor for circletype is

circletype::circletype(double initial_x, double initial_y, float radius_value)
    {
        set_x(initial_x);
        set_y(initial_y);
        radius = radius_value;
    }

Here is the code for point.h in its entirety.

    class point
    {
    public:
        // CONSTRUCTOR
        point(double initial_x, double initial_y);
        // MODIFICATION MEMBER FUNCTIONS
        void shift(double x_amount, double y_amount);
        void rotate90( );
        void set_x(double x_amount);
        void set_y(double y_amount);
        // CONSTANT MEMBER FUNCTIONS
        double get_x( ) const { return x; } 
        double get_y( ) const { return y; }
    private:
        double x; // x coordinate of this point
        double y; // y coordinate of this point
    };
    
    



class circletype:public point
    {
    public:
    //CONSTRUCTOR
         circletype(double initial_x, double initial_y, float radius_value);
    //MODIFICATION MEMBER FUNCTIONS
         void set_radius(float radius);
    //CONSTANT MEMBER FUNCTIONS
         float get_radius() const;
    
    private:
         float radius;
    };

Here is point.cpp

#include "point.h"


    
    point::point(double initial_x, double initial_y)
    {
        x = initial_x;   // Constructor sets the point to a given position.
        y = initial_y;
    }

    
    void point::shift(double x_amount, double y_amount)
    {
        x += x_amount;
        y += y_amount;   
    }

    
    void point::rotate90( )
    {
        double new_x;
        double new_y;

        new_x = y;  // For a 90 degree clockwise rotation, the new x is the original y,
        new_y = -x; // and the new y is -1 times the original x.
        x = new_x;
        y = new_y; 
    }
    
    void point::set_x(double x_amount)
    {
         x = x_amount;
    }
    
    void point::set_y(double y_amount)
    {
         y = y_amount;
    }
    

  circletype::circletype(double initial_x, double initial_y, float radius_value)
    {
        set_x(initial_x);
        set_y(initial_y);
        radius = radius_value;
    }

It's my first time with derived classes, and I'm really not sure what I'm doing wrong. I'd appreciate any advice.

As point class has no c'tor without parameters and when you create a Circletype you also create a point, what the compiler complains about is that it cannot decide how to create the point class without any parameters.. as far as i see you are using the first two parameters (double initial_x, double initial_y) to initalize the members inherited from point.. so simply you can pass these two to point class and let it do its job:

circletype::cir cletype(double initial_x, double initial_y, float radius_value) :
point (double initial_x, double initial_y)
{
radius = radius_value;
}

That was it. Thank you very much.
