<p><span class="def">assign(cset& s, const char* setinit)</span> works the same
way as <span class="lang">cset(const char*)</span> constructor (see <a href="cset.constructors.html">constructors</a>).</p>
<p><span class="def">string asstring(const cset& s)</span> returns a string
representing the given set <span class="lang">s</span> using <span class="lang">cset(const
char*)</span> syntax. Typically used for debugging.</p>
<p><span class="def">clear(cset& s)</span> assigns an empty set (removes all
members) to the set <span class="lang">s</span>.</p>
<p><span class="def">fill(cset& s)</span> assigns all 1s to the set - all elements
become members of this set.</p>
<p><span class="def">include(cset& s, char b)</span> adds the element <span class="lang">b</span>
to the set <span class="lang">s</span>. Equivalent to <span class="lang">s +=
b</span>.</p>
<p><span class="def"> include(cset& s, char min, char max)</span> adds a range
of elements <span class="lang">min</span> through <span class="lang">max</span>
to the set <span class="lang">s</span>.</p>
<p> <span class="def">exclude(cset& s, char b)</span> removes the element <span class="lang">b</span>
from the set <span class="lang">s</span>. Equivalent to <span class="lang">s -=
b</span>.</p>
