I have faced a programmatic error from the following code which I need to create TOYOTA LOGO using C++. This result is attached. your support is highly appreciated.

#include <GL/glut.h>
#include <math.h>

void drawEllipse(float centerX, float centerY, float radiusX, float radiusY)
{
    glBegin(GL_TRIANGLE_FAN);
    for (int angle = 0; angle <= 360; angle++)
    {
        float radians = angle * M_PI / 180;
        float x = centerX + radiusX * cos(radians);
        float y = centerY + radiusY * sin(radians);
        glVertex2f(x, y);
    }

    glEnd();
}

void display()
{
    glClear(GL_COLOR_BUFFER_BIT); // Clear the screen

    // Draw red ellipse (outermost)
    glColor3f(1.0f, 0.0f, 0.0f); // Set color to red
    drawEllipse(0.0f, 0.0f, 0.6f, 0.3f);

    glColor3f(0.0f, 0.0f, 0.0f); // Set color to Inner red hole
    drawEllipse(0.0f, 0.0f, 0.4f, 0.2f);

   // Draw Green ellipse (innermost)
   glColor3f(2.0f, 2.0f, 2.0f); // Set color to white
   drawEllipse(0.0f, 0.1f, 0.5f, 0.2f);

   glColor3f(0.0f, 0.0f, 0.0f); // Set color to white
   drawEllipse(0.0f, 0.1f, 0.40f, 0.1f);

   // Draw silver ellipse (middle)
   glColor3f(6.3f, 6.3f, 6.3f); // Set color to middle
   drawEllipse(0.0f, 0.0f, 0.15f, 0.25f);

   glColor3f(0.0f, 0.0f, 0.0f); // Set color to inner middle
   drawEllipse(0.0f, 0.0f, 0.10f, 0.23f);

   glFlush(); // Swap buffers to display drawing
}

int main(int argc, char** argv)
{
    glutInit(&argc, argv); // Initialize GLUT
    glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB); // Set display mode
    glutInitWindowSize(500, 500); // Set window size
    glutInitWindowPosition(100, 100); // Set window position
    glutCreateWindow("Toyota Logo"); // Create window with title
    glutDisplayFunc(display); // Set display callback function

    glutMainLoop(); // Enter main loop for event handling and drawing
    return 0;
}

I believe that people in this community will fix my problem.
