Display glutDisplayFunc function in loop

I want to call the glutDisplayFunc function again in loop but it's error. How to solve this problem?

    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_RGB);
    glutInitWindowSize(1000, 1000);
    glutInitWindowPosition(0, 0);
    glutCreateWindow("simple");
    for (int m = 0; m <= l; m++) {
        cout << "Please enter a stage: ";
        cin >> num;
        glutDisplayFunc(display);
    }
    initializeGL();
    glutMainLoop();

glutDisplayFunc does not call the function you pass to it itself. It basically stores which function should be called inside the glutMainLoop().

In the glut main-loop the rendering function is then called whenever necessary. If you want it to redraw as fast as possible, call glutPostRedisplay(); at the end of the display function.
