OpenGL square not showing up..

Hi, so im new to graphics programming and decided to try openGL (I'm planning on making a 2D game in it at first, possibly pacman). And I'm having trouble getting it to draw shapes on the screen.

Code:

---

#include "glut.h"

#define WIDTH 350
#define HEIGHT 500

void display();

void display()
{
        glClearColor(1.0, 0.0, 0.0, 1.0);
        glClear(GL_COLOR_BUFFER_BIT);
        glLoadIdentity();
        glTranslatef(0.0, 0.0, -5.0);
        glBegin(GL_QUADS);
        glVertex3f(-1.0f, -1.0f, 0.0f);
        glVertex3f(-1.0f, 1.0f, 0.0f);
        glVertex3f(1.0f, 1.0f, 0.0f);
        glVertex3f(1.0f, -1.0f, 0.0f);
        glEnd();

        glFlush();
}

int main(int argc, char **argv)
{
        glutInit(&argc, argv);
        glutInitDisplayMode(GLUT_SINGLE);
        glutInitWindowSize(WIDTH, HEIGHT);
        glutInitWindowPosition(100, 100);
        glutCreateWindow("PacMan");
        glutDisplayFunc(display);
        glutMainLoop();
}

also once i get to the point of coding a pacman game.. would the best method be to use and array to represent a tile like system to draw the game boards, and to be used with the ghost AI

Just venturing a guess here: replace GLUT_SINGLE by GLUT_DOUBLE and replace glFlush() by glutSwapBuffers().

The problem still persists. Its just a blank red screen. I'm wondering if its the xyz positions? I'm just a newb at this graphics stuff though

Have you read this tutorial series?
NeHe Productions: OpenGL Lesson #02

I went with a different tutorial series, because of it using glut to create the window instead of the WINAPI. the link to the tutorial Swiftless OpenGL Tutorials | Swiftless Tutorials I created this set of code by myself, and when it didnt work i reffered back to the tutorial code but im failing to see whats wrong(evidently something is)

Off-hand, maybe
a) it's very small (like 1x1 pixel)
b) it's also coloured red

You haven't set-up your projection matrix, as a result, when you translate your geometry beyond -1.0 in z-direction, it is outside your far clipping plane, i.e. you can't see it. You should set-up your projection matrix. Refer to the GLUT code for 'Lesson 02: Your first polygon' in the NeHe tutorial database.
Long story short: you have to register a callback through glutReshapeFunc, which gets called eveytime your window changes dimensions (and also when it is first created). You switch to the projection matrix (glMatrixMode(GL_PROJECTION)), and set-up the desired projection transforms (a call to gluPerspective usually does the trick).

In any case, I would recommend you either follow through NeHe's tutorials (which also include code for GLUT), or download a (freely available) copy of the (outdated, but still useful for beginners, version) of the OpenGL redbook.

EDIT: opengl.org seems to be unreachable at the moment...

The projection matrix was the problem.. I feel dumb because I tried to avoid the reshape function for this but as I found out it was definately needed. Thanks for the help guys.
