Derive a second class

This is only my second C++ assignmet. I have been working on this all day. The question is a 2 part question. the first part is as follows,
A point in the x-y plane is represented by it's x-coordinate and y-cordinate. Design a class, pointType, that can store and proccess a point in the x-y plain.you should then perform operations on the point, such as showing the point, setting the point, returning the x-coordinate and returning the y-coordinate.Also write a test program to test the various operations on the point.

second part.
Every circle has a center and a redius.Given the radius, we can determine the circle's area and circumference.Given the center we can determine the circles position in the x-y plane.The center of a circle is a point in teh x-y plane. Designe a class, circleType that can store a radius and the center of the circle.Because the center is a point in the x-y plane and you designed the class to capture the properties of a point in preceeding exercise. You must derive a class circleType from the class pointType. You should be able to perform the usual operations on a circle, such as setting the radius, printing the redius, calculating and printing the area and circumference, and carring out the usual operations on the center.

I am able to get the first part of the exercie. however I don't know what they mean by writing a test program
As you will see I created a class cicrleType within the same project. However after creating class circleType I get the error "main.cpp|9|circleType.h: No such file or directory"
I am using code blocker. I know that i have to still work on the circleType files which will not be an issue, I just don't know why code blocker is not seeing circleType.h


main.cpp

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

int main()
{
    double Coordinate_x;
    double Coordinate_y;


cout << "Enter the x and y coordinate " << endl;
cin >> Coordinate_x >> Coordinate_y;
cout << "Enter the radus of the circle" <<endl;

cout << "The X and Y Coordinates are: (" <<Coordinate_x <<"," << Coordinate_y<< ")"
<< endl;
cout << "The Area if the circe ";
cout <, "The circumferance of the circke is ";

}
