从键盘输入30名学生的成绩数据求其中的最高分，最低分和平均分

用数组存放成绩，作业写不出来了😭

<span class="hljs-meta">#<span class="hljs-keyword">include</span><span class="hljs-string"><stdio.h></span></span>
<span class="hljs-meta">#<span class="hljs-keyword">define</span> M 30</span>
main ( )
{ float <span class="hljs-built_in">score</span>[M], <span class="hljs-built_in">max</span> , <span class="hljs-built_in">min</span>, aver;
int i ;
printf(<span class="hljs-string">"please input score: \n"</span>);
<span class="hljs-keyword">for</span>(i=<span class="hljs-number">0</span>; i<M ; i++)
scanf(<span class="hljs-string">"%f"</span>, &<span class="hljs-built_in">score</span>[i]);
aver = <span class="hljs-number">0.0</span>;
<span class="hljs-built_in">min</span> = <span class="hljs-built_in">max</span> = <span class="hljs-built_in">score</span>[<span class="hljs-number">0</span>];
<span class="hljs-keyword">for</span>(i = <span class="hljs-number">0</span>; i < M; i++)
{
<span class="hljs-keyword">if</span>(<span class="hljs-built_in">min</span> > <span class="hljs-built_in">score</span>[i])
<span class="hljs-built_in">min</span>= <span class="hljs-built_in">score</span>[i];
<span class="hljs-keyword">if</span>(<span class="hljs-built_in">max</span> < <span class="hljs-built_in">score</span>[i])
<span class="hljs-built_in">max</span> = <span class="hljs-built_in">score</span>[i];
aver += <span class="hljs-built_in">score</span>[i];
}
printf(<span class="hljs-string">"max=%f, min=%f,aver=%f"</span>, <span class="hljs-built_in">max</span>, <span class="hljs-built_in">min</span>, aver/M);
}

如果有帮助请点一下我回答右上方的采纳，谢谢！以后有什么问题可以互相交流。
