open gl basic program error?

#include <stdio.h>
#include<stdlib.h>
#include<windows.h>
#include<GL/glut.h>

void display (void)
{
    glClearColor(1.f, 0.f, 0.f, 1.f);
    glEnd();
    glFlush();
}

int main(int argc, char **argv)
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_SINGLE);
    glutInitWindowSize(500,500);
    glutInitWindowPosition(100,100);
    glutCreateWindow("Colorcube Viewer");
    glutDisplayFunc(display);
    glEnable(GL_DEPTH_TEST);
    glutMainLoop();
    return 0;
}

i am not able to figure out whats the problem with this code ?
it does not give me a red window.

You need to call glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); after setting the clear color (because you have depth test enabled, make sure that you're clearing both the color buffer AND the depth buffer
