      <description>&lt;!-- 笔试题有的时候不给正常输入，只给plain text --&gt;


&lt;h2 class=&#34;relative group&#34;&gt;Format Specifier 
    &lt;div id=&#34;format-specifier&#34; class=&#34;anchor&#34;&gt;&lt;/div&gt;
    
    &lt;span
        class=&#34;absolute top-0 w-6 transition-opacity opacity-0 ltr:-left-6 rtl:-right-6 not-prose group-hover:opacity-100&#34;&gt;
        &lt;a class=&#34;group-hover:text-primary-300 dark:group-hover:text-neutral-700&#34;
            style=&#34;text-decoration-line: none !important;&#34; href=&#34;#format-specifier&#34; aria-label=&#34;Anchor&#34;&gt;#&lt;/a&gt;
    &lt;/span&gt;        
    
&lt;/h2&gt;
&lt;p&gt;Common specifiers:&lt;/p&gt;
&lt;pre tabindex=&#34;0&#34;&gt;&lt;code&gt;%d      int
%u      unsigned int
%c      char
%s      string (char s[])
%p      void*
%ld     long
%lld    long long (64bits)
%f      float/double
%lf     float/double(usually used in scanf)
&lt;/code&gt;&lt;/pre&gt;&lt;p&gt;We can extend the format specifiers:&lt;/p&gt;
&lt;div class=&#34;highlight&#34;&gt;&lt;pre tabindex=&#34;0&#34; class=&#34;chroma&#34;&gt;&lt;code class=&#34;language-C&#34; data-lang=&#34;C&#34;&gt;&lt;span class=&#34;line&#34;&gt;&lt;span class=&#34;cl&#34;&gt;&lt;span class=&#34;nf&#34;&gt;printf&lt;/span&gt;&lt;span class=&#34;p&#34;&gt;(&lt;/span&gt;&lt;span class=&#34;s&#34;&gt;&amp;#34;%5d&amp;#34;&lt;/span&gt;&lt;span class=&#34;p&#34;&gt;,&lt;/span&gt; &lt;span class=&#34;mi&#34;&gt;33&lt;/span&gt;&lt;span class=&#34;p&#34;&gt;);&lt;/span&gt;       &lt;span class=&#34;c1&#34;&gt;// width      &amp;#34;   33&amp;#34;   
&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;span class=&#34;line&#34;&gt;&lt;span class=&#34;cl&#34;&gt;&lt;span class=&#34;c1&#34;&gt;&lt;/span&gt;&lt;span class=&#34;nf&#34;&gt;printf&lt;/span&gt;&lt;span class=&#34;p&#34;&gt;(&lt;/span&gt;&lt;span class=&#34;s&#34;&gt;&amp;#34;%.2f&amp;#34;&lt;/span&gt;&lt;span class=&#34;p&#34;&gt;,&lt;/span&gt; &lt;span class=&#34;mf&#34;&gt;3.14159&lt;/span&gt;&lt;span class=&#34;p&#34;&gt;);&lt;/span&gt; &lt;span class=&#34;c1&#34;&gt;// precision  &amp;#34;3.14&amp;#34;
&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;span class=&#34;line&#34;&gt;&lt;span class=&#34;cl&#34;&gt;&lt;span class=&#34;c1&#34;&gt;&lt;/span&gt;&lt;span class=&#34;nf&#34;&gt;printf&lt;/span&gt;&lt;span class=&#34;p&#34;&gt;(&lt;/span&gt;&lt;span class=&#34;s&#34;&gt;&amp;#34;%8.2f&amp;#34;&lt;/span&gt;&lt;span class=&#34;p&#34;&gt;,&lt;/span&gt; &lt;span class=&#34;mf&#34;&gt;3.14159&lt;/span&gt;&lt;span class=&#34;p&#34;&gt;);&lt;/span&gt;&lt;span class=&#34;c1&#34;&gt;// &amp;#34;    3.14&amp;#34;
&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;span class=&#34;line&#34;&gt;&lt;span class=&#34;cl&#34;&gt;&lt;span class=&#34;c1&#34;&gt;&lt;/span&gt;&lt;span class=&#34;nf&#34;&gt;printf&lt;/span&gt;&lt;span class=&#34;p&#34;&gt;(&lt;/span&gt;&lt;span class=&#34;s&#34;&gt;&amp;#34;%-5d&amp;#34;&lt;/span&gt;&lt;span class=&#34;p&#34;&gt;,&lt;/span&gt; &lt;span class=&#34;mi&#34;&gt;33&lt;/span&gt;&lt;span class=&#34;p&#34;&gt;);&lt;/span&gt;      &lt;span class=&#34;c1&#34;&gt;//Alignment   &amp;#34;33   &amp;#34;
&lt;/span&gt;&lt;/span&gt;&lt;/span&gt;&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;

&lt;h2 class=&#34;relative group&#34;&gt;IO 
    &lt;div id=&#34;io&#34; class=&#34;anchor&#34;&gt;&lt;/div&gt;
    
    &lt;span
        class=&#34;absolute top-0 w-6 transition-opacity opacity-0 ltr:-left-6 rtl:-right-6 not-prose group-hover:opacity-100&#34;&gt;
        &lt;a class=&#34;group-hover:text-primary-300 dark:group-hover:text-neutral-700&#34;
