【第二周练兵区编程题第四题】为什么我写的总是让exe停止运行

<p><code class="brush:cpp;toolbar:false" >#include&lt;stdio.h&gt; int&nbsp;main() { &nbsp;&nbsp;&nbsp;&nbsp;int&nbsp;n,a,b; &nbsp;&nbsp;&nbsp;&nbsp;printf(&quot;输入一个四位数:&quot;); &nbsp;&nbsp;&nbsp;&nbsp;scanf(&quot;%d&quot;,n); &nbsp;&nbsp;&nbsp;&nbsp;a=n/100; &nbsp;&nbsp;&nbsp;&nbsp;b=n%100; &nbsp;&nbsp;&nbsp;&nbsp;printf(&quot;a=%d,b=%d\n&quot;,a,b); &nbsp;&nbsp;&nbsp;&nbsp;printf(&quot;a+b=%d\n&quot;,a+b); &nbsp;&nbsp;&nbsp;&nbsp;printf(&quot;a-b=%d\n&quot;,a-b); &nbsp;&nbsp;&nbsp;&nbsp;printf(&quot;a*b=%d\n&quot;,a*b); &nbsp;&nbsp;&nbsp;&nbsp;printf(&quot;a/b=%.2f\n&quot;,a*1.00/b); &nbsp;&nbsp;&nbsp;&nbsp;printf(&quot;a%b=%d\n&quot;,a%b); &nbsp;&nbsp;&nbsp;&nbsp;return&nbsp;0; }</code>可以调试但是一输入四位数就停止运行了</p>
