Error in the book


#1

in the page 136 i have this code:

for (float currentRadius = maxRadius; currentRadius §g_ 0; currentRadius -= 20) {
        //Ajoute un chemin au contexte
        CGContextAddArc(ctx, center.x, center.y , currentRadius, 0.0, M_PI*2.0, YES);
        //Instruction de tracé; supprime le chemin
        CGContextStrokePath(ctx);
}

It makes an error because this in the first line:
currentRadius §g_ 0

If i erase the “§g_ 0” then i run the code i got a black screen.

I didn’t find anything about this.

thanks

I find the issue

the mistake is solved if you replace §g_ by >
