<h3>Unary Operators<a class="headerlink" href="#unary-operators" title="Permalink to this headline">¶</a></h3>

<p>Unary operators require only a single operand and produce a result based on their values. Some unary operators will
|
|
|
|
|
change the value of their operands. For example:</p>
|
|
|
|
|
<div class="highlight-default"><div class="highlight"><pre><span></span><span class="n">i</span> <span class="o">=</span> <span class="mi">0</span><span class="p">;</span>

<span class="o">++</span><span class="n">i</span><span class="p">;</span>
|
|
|
|
|
</pre></div>
|
|
|
|
|
</div>
|
|
|
|
|
<p>Running the pre-increment unary operator (++) in the code above changes the value of the variable i.</p>
