hello,this is my code #ifdef __APPLE_CC__

include <glut glut.h="">

else

include <gl glut.h="">

endif

include<gl glut.h="">

include <cmath>

include <math.h>

GLfloat x; GLfloat y; GLfloat radius; void drawcir(GLfloat x, GLfloat y, GLfloat radius); void init() {

glClearColor(0,0,0,0); glMatrixMode(GL_PROJECTION); gluOrtho2D(0,100,0,200);

}

void drawcir(GLfloat x, GLfloat y, GLfloat radius){ int i; int k; int lineamount= 8; radius=4; x=0; y=0; GLfloat twicepi=2.0*3.14;

glBegin(GL_LINE_LOOP);
    for(k=0;k<=3;k++){
        for(i=0;i<=lineamount;i++){
            glVertex2f( 
                x+ (radius * cos(i * twicepi / lineamount)),y + (radius * sin(i * twicepi / lineamount)));
        }
    radius--;
    }
glEnd();
}

void display() { void drawcir(GLfloat x, GLfloat y, GLfloat radius); } //glFlush();

int main(int argc,char **argv)

{ glutInit(&argc,argv);

glutInitDisplayMode(GLUT_SINGLE|GLUT_RGB); glutInitWindowSize(500,500); glutInitWindowPosition(200,200); glutCreateWindow("Line"); init(); //drawcir(GLfloat (x), GLfloat(y), GLfloat (radius)); glutDisplayFunc(display);

glutMainLoop(); return 0; } but i can't see the output it just shows this message 'new code.exe': Loaded 'C:\Users\sarah\Documents\Visual Studio 2010\Projects\new code\Debug\new code.exe', Symbols loaded.
