<h3>虾米大王填写的作业题05</h3>
<h4>一、填空题</h4>
<p>1. 运算符很多，主要由<input type="text" value="+">、<input type="text" value="-">、
<input type="text" value="*">、<input type="text" value="/">。</p>
<p>2. PHP的位运算符主要有<input type="text" value="&">、<input type="text" value="|">、
<input type="text" value="~">、<input type="text" value="^">、
<input type="text" value="<<">和<input type="text" value=">>">。</p>
<h4>二、选择题</h4>
<div>
<p>1. 赋值运算符“%=”的意义是( )</p>
<ol type="A">
<li><input type="radio" name="title_1" checked="checked">将左边的值对右边取余数赋给左边</li>
<li><input type="radio" name="title_1">将左边的值除以右边的值赋给左边</li>
<li><input type="radio" name="title_1">将右边的值对左边取余数赋给左边</li>
<li><input type="radio" name="title_1">将右边的值除以左边的值赋给左边</li>
</ol>
</div>
<div>
<p>2. 逻辑运算符“Xor”的意义是( )</p>
<ol type="A">
<li><input type="radio" name="title_2">$a和$b不同时为真，则结果为假</li>
<li><input type="radio" name="title_2">$a和$b同时为真，则结果为真</li>
<li><input type="radio" name="title_2" checked="checked">$a和$b不同时为真，则结果为真</li>
<li><input type="radio" name="title_2">以上都不对</li>
</ol>
</div>
<div>
<p>3. 下面程序的运行结果是( )</p>
<p><?php</p>
<P>$a = 1;</P>
<p>$a++;</p>
<p>$c = &$a;</p>
<p>$b = $c++;</p>
<p>echo "\$a = $a <br> \$b = $b <br> \$c = $c <br>";</p>
<P>?></P>
<ol type="A">
<li><input type="radio" name="title_3" checked="checked">$a = 3 $b = 2 $c = 3</li>
<li><input type="radio" name="title_3">$a = 3 $b = 2 $c = 2</li>
<li><input type="radio" name="title_3">$a = 2 $b = 2 $c = 3</li>
<li><input type="radio" name="title_3">$a = 2 $b = 2 $c = 2</li>
</ol>
</div>
</body>
