Very new at openGL, can someone help me with this code and explain why it wont draw?

Sorry to do this to all of you but I cant understand why this code wont draw a simple triangle. If someone could explain what is going on I would really appreciate it.

Here is the code:

#include<glut.h>

void display()
{
glClear(GL_COLOR_BUFFER_BIT);
glColor3f(1.0,0.0,0.0);

glBegin(GL_TRIANGLES);
	glVertex3f(0.0,25.0,0.25);
glEnd();

glFlush();

}

void init()
{
glClearColor(0.0,0.0,0.0,0.0);

glMatrixMode(GL_PROJECTION);
glLoadIdentity();
glOrtho(-50.0,50.0,-50.0,50.0,-1.0,1.0);

}

int main(int argc, char** argv)
{
glutInit(&argc,argv);
glutInitDisplayMode(GLUT_SINGLE|GLUT_RGB);
glutInitWindowSize(250,250);
glutInitWindowPosition(200,200);
glutCreateWindow(“Program1”);

init();
glutDisplayFunc(display);
glutMainLoop();
return 0;

}

Hehe, never mind. I figured it out myself.
Sorry to post such a dumb question. Im sure you guys will be hearing alot from me. hehe

You need to supply each of the triangles corners.

glBegin(GL_TRIANGLES);
glVertex3f(0.0,25.0,0.25);
glVertex3f…
glVertex3f…
glEnd();
