But any real Jolt-swilling, bit-banging 'C' coder would write:
for (i = 0; i < num_thingies; ++i) {
fprintf(ostr, "<tr class=\"%s\"><td>%s</td></tr>\n",
(i & 1 ? "blue" : "yellow"),
thingies[i]);
}
:-)
(The COBOL & PL/1 guys, who use the operators just like they're supposed to
be used, would need % because they are used to three-color bar paper,
anyway. But they should be happy with "mod" anyway, for obvious reasons.)
