1)编写一个程序,实现顺序表的各种基本操作(假设顺序表的元素类型为学生记录,包括学号! 姓名和成绩),并在此基础上设计一个主程序完成如下功能: (2)初始化顺序表 SeqList; (3)输入顺序表的元素(5 条记录) (4)编写 PrintList 函数,输出顺序表 SeqList 所有元素; (5)编写 LocateElement 函数,查找顺序表元素的位置; (6)编写 InsertElement 函数,向顺序表中插入新元素,并调用该函数,在第 3个元素位 置上插人一条学生记录; (7)编写 DeleteElement 函数,删除顺序表元素,并调用该函数删除顺序表 SeqList 的第 1 个元素,输出删除后的线性表;
