c++实现线性表中的顺序表（数据结构课程作业）

一、题目简介

实现顺序表的创建、初始化、赋值、插入、删除、按数据查找元素位置、按元素位置查找数据、清空、删除

的操作，以上操作用可用菜单选项完成

二、源程序代码

#include<iostream>
#define MAXSIZE 100
using namespace std;
   typedef int ElemType;
   typedef struct List
   {
      ElemType *elem;
      int length;
   }Sqlist;
   void InitList(Sqlist &L);
   void DestroyList(Sqlist &L);
   void ClearList(Sqlist &L);
   void GetLength(Sqlist L);
   void isEmpty(Sqlist L);
   void Getelem(Sqlist &L,int i);
   void Locateelem(Sqlist &L,ElemType e);
   void ListInsert(Sqlist &L,int i,ElemType e);
   void ListDelete(Sqlist &L,int i);
   void fuzhi(Sqlist &L);
   void print(Sqlist &L);
   void mainscreen();
   int main()
   {
     mainscreen();
     return 0;
   }
  void InitList(Sqlist &L)
   {

   }
