大一学生c语言，头都秃了

​
这是一个高考录取系统，假定当年该省的招生计划是：一类本科招生计划为10％；二类本科招生计划为15％；三类本科招生计划为20％；四类高职高专招生计划为25％。

请问为什么输出时只有总分排名中间部分的学生录取了，高分和低分的都没被录取呢 

 以下是代码，是不是计算招生计划的void calculate_admission_plan()这块有问题？

我想先按成绩高到低排，然后再按比例录用，请问有更好的办法吗

存在以下问题：
函数calculate_admission_plan中的变量ini没有定义，应该删去；变量total_num没有初始化，应该赋初值0；招生计划人数计算公式有误，应该是 plans[i].num = plans[i].ratio * num_students;。；招生计划人数计算有误，最后一个招生计划的人数应该是 plans[i].num = total_num - plans[i - 1].num;计算招生计划最低分数线的方法有误，应该在分配录取名单时记录最后一个被录取的考生的总分，将其作为该招生计划的最低分数线。
函数load_students中的fscanf语句的格式字符串中缺少一个%d，应该为"%s %s %s %s %d %d %d %d %d %d %d %d\n"。
函数search_student中没有考虑到当查询关键字不存在时的情况，应该加入相应的提示。
函数print_students中的switch语句缺少break语句，应该在每个case语句块的末尾添加break语句。修改后的代码如下：
