Answer 1

#include <freeglut.h>
#include <stdio.h>

static void RenderScene(void) {
    glClear(GL_COLOR_BUFFER_BIT);
    glutSwapBuffers();
}

int main(int argc, char** argv)
{
    glutInit(&argc, argv);
    glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGBA | GLUT_DEPTH);

    int width = 800;
    int height = 600;
    glutInitWindowSize(width, height);

    int win = glutCreateWindow("freeglut - glutCreateWindow() Example");
    printf("window id: %d\n", win);

    GLclampf Red = 0.0f, Green = 0.0f, Blue = 0.0f, Alpha = 0.0f;
    glClearColor(Red, Green, Blue, Alpha);

    glutDisplayFunc(RenderScene);

    glutMainLoop();

    return 0;
}
