1、微機原理與接口技術題：一個學生的信息包括姓名、班級、學號、成績，其中成績需要精確到一位小數。試編寫程序實現以下功能：（ 1）可以錄入學生成績（十進制形式） ；（ 2）可以按要求（如學號或成績）進行排序顯示；（ 3）可以統(tǒng)計平均成績；（ 4）可以統(tǒng)計不及格、 6070、7080、8090、90100 各分數段的人數。;數組： name：存放姓名s_id：存放學號s_id1：存放排序后的學號number：原先排列序號number1：排序后的排列序號grade：學生成績grade1：經過排序后的學生成績data segmentsname db whq , yxm , dxq , yhh , fww
