Cannot Draw Ellipse

I’m trying to draw an ellipse and tried google and I have failed to make any useful progress. Here Are the codes I took on the internet and did a lot of modification, adding and removing to suit my needs and it does not work.
Please help me point what is wrong
Thanks
main.h

#include <GL/glut.h>
#include <cmath>
using namespace std;

//initiate display
void glutIniStuffs(int argc, char** argv) ;

//Create the window
int glutCreateWindow(char *title);

//Render our scene
void drawScene();

void changeSize(int w, int h);

//Register all call backs here
void registerCallBacks();

void drawEllipse(float radiusX, float radiusY);

main.cpp

#include "main.h"

void glutIniStuffs(int argc, char** argv) {
	glutInit(&argc, argv);
	glutInitDisplayMode(GLUT_DEPTH | GLUT_DOUBLE | GLUT_RGBA);
	glutInitWindowSize(500, 500); // window size
	glutInitWindowPosition((glutGet(GLUT_SCREEN_WIDTH)-640)/2, (glutGet(GLUT_SCREEN_HEIGHT)-480)/2);  // window location
}

#define DEG2RAD 3.14159/180.0

void drawEllipse(float radiusX, float radiusY) {
	int i;
	
	glBegin(GL_LINE_LOOP);
	
	for(i=0; i<360; i++) {
		float rad = i*DEG2RAD;
		glVertex2f(cos(rad)*radiusX,
		           sin(rad)*radiusY);
	}
	
	glEnd();
}

void drawScene() {
	glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
	glColor3f(0.9f, 0.0f, 0.9f);
	GLfloat axisZ = -15;
	//glTranslated(-1.25, -1, 1);
	
	drawEllipse(2.0, 2.8);
	
	glutSwapBuffers();
}



void registerCallBacks() {
	// register callbacks
	
	//Draw function
	glutDisplayFunc(drawScene);
	
	//redraw function
	glutReshapeFunc(changeSize);
}

void changeSize(int w, int h) {

	// Prevent a divide by zero, when window is too short -- (you cant make a window of zero width).
	if(h == 0) {
		h = 1;
	}
	
	float winRatio = 1.0* w / h;
	
	// Set the viewport to be the entire window
	glViewport(0, 0, w, h);
	
	// Use the Projection Matrix
	glMatrixMode(GL_PROJECTION);
	
	// Reset Matrix
	glLoadIdentity();
	
	// Set the correct perspective.
	// Set the Field of view angle (in degrees), the aspect ratio of our window, and the new and far planes
	gluPerspective(60, winRatio, 1.0, 100.0);
	
	// Get Back to the Modelview
	glMatrixMode(GL_MODELVIEW);
	
	
}


int main(int argc, char** argv) {
	//initalize glut
	glutIniStuffs(argc, argv);
	
	//create window
	glutCreateWindow("House Made with OpenGL");
	
	//register callbacks
	registerCallBacks();
	glutMainLoop();
	return 0;
}

Hi, I think u should try adding in orthographic projection first to make sure that u get something on screen. Replace the gluPerspective call with this and see if u get something on screen.

gluOrtho2D(-10,10,-10,10);

I Fixed it with codes below. Let me close this and open another thread because I have another problem

main.h

#include <GL/glut.h>
#include <cmath>
using namespace std;

//initiate display
void glutIniStuffs(int argc, char** argv) ;

//Create the window
int glutCreateWindow(char *title);

//Render our scene
void drawScene();

void changeSize(int w, int h);

//Register all call backs here
void registerCallBacks();

void drawEye(float radiusX, float radiusY);
void drawCircle(float x, float y, float r);

main.cpp

#include "main.h"

void glutIniStuffs(int argc, char** argv) {
	glutInit(&argc, argv);
	glutInitDisplayMode(GLUT_DEPTH | GLUT_DOUBLE | GLUT_RGBA);
	glutInitWindowSize(500, 500); // window size
	glutInitWindowPosition((glutGet(GLUT_SCREEN_WIDTH)-640)/2, (glutGet(GLUT_SCREEN_HEIGHT)-480)/2);  // window location
}

#define DEG2RAD 3.14159/180.0

void drawEye(float radiusX, float radiusY) {
	int i;
	
	glBegin(GL_LINE_LOOP);
	
	for(i=0; i<360; i++) {
		float rad = i*DEG2RAD;
		glVertex2f(cos(rad)*radiusX,
		           sin(rad)*radiusY);
	}
	
	glEnd();
}

void drawCircle(float x, float y, float r) {
	
}


void drawScene() {
	glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
	glColor3f(1.0f, 0.0f, 0.0f);
	
	drawEye(22.8, 12.0);
	drawCircle(2, 4, 10);
	
	glutSwapBuffers();
}



void registerCallBacks() {
	// register callbacks
	
	//Draw function
	glutDisplayFunc(drawScene);
	
	//redraw function
	glutReshapeFunc(changeSize);
}

void changeSize(int w, int h) {
	glViewport(0, 0, (GLsizei) w, (GLsizei) h);
	glMatrixMode(GL_PROJECTION);
	glLoadIdentity();
	glOrtho(-50.0, 50.0, -50.0, 50.0, -1.0, 1.0);
	glMatrixMode(GL_MODELVIEW);
	glLoadIdentity();
}


int main(int argc, char** argv) {
	//initalize glut
	glutIniStuffs(argc, argv);
	
	//create window
	glutCreateWindow("House Made with OpenGL");
	
	//register callbacks
	registerCallBacks();
	glutMainLoop();
	return 0;
}

Please mod, help me mark it solved!
