		rwmj on May 9, 2020 \| parent \| context \| favorite \| on: Revisiting the Business Card Raytracer Is there a mistake in the original code on the right hand side? I get: `card.cpp:16:2: error: ‘g’ was not declared in this scope 16 \| <g;p)t=p,n=v(0,0,1),m=1;for(i k=19;k--;) \| ^` Edit: Yes there is. The ‘<g;’ seems like it should have been the single character ‘<’, perhaps a corrupted HTML escape.

(Original author of this code[0] here.) Yes, that looks like a corrupted copy. The line should be:

    <p)t=p,n=v(0,0,1),m=1;for(i k=19;k--;)

Yep, I got the same error. The version here [0] works fine.
