Display Counter

OpenGL OpenGL: Basic Coding

Hi, I’m trying to display a counter that counts up to 30 seconds on my openGl program. The counter works fine and I can see it running in the console window, the only problem is I cant get it to show up in the openGL window, A 1 flashes up and then nothing after that.

Here is my current function for displaying this:

void pause(int a)
{
startTimer();
}

void startTimer()
{
int num_1 = i % 10;
int num_10 = (i / 10) % 10;

i++;
if(i<=31)
{
	if (num_10){
		glRasterPos2f(1, 1);
		glutBitmapCharacter(GLUT_BITMAP_9_BY_15 , 48 + num_10);
		std::cout<<num_10;
	}
	glRasterPos2f(1, 1);
	glutBitmapCharacter(GLUT_BITMAP_9_BY_15 , 48 + num_1);
	std::cout<<num_1;

	glutTimerFunc(1000,pause,0);
}

}

Any ideas?
