本文实例为大家分享了C++实现基于静态数组的顺序表，供大家参考，具体内容如下
实现的基本操作有：
1. 初始化
2. 尾插
3. 尾删
4. 头插
5. 头删
6.查找任意元素
7. 读任意位置元素
8. 修改任意位置元素
9. 查找指定元素值的下标
10. 在任意位置插入元素
11.删除指定位置的元素
12.删除任意元素
13.打印数据
头文件seqlist.h:
#pragma once
#include<stdio.h>
#include<stdlib.h>
#include<assert.h>
#define maxsize 1000//链表最多元素个数
typedef int seqType;
typedef struct seqlist
{
seqType arr[maxsize];//数据域，存放数据
size_t size;//size_t是无符号长整型，是一种类型,size在数组中表示元素个数
}seqlist ;
void PrintSeqList(seqlist *seq); //打印数据
void print_seqlist(char *s); //打印标题
void seqlistInit(seqlist *seq); //链表初始化
void seqlistPushBack(seqlist *seq, seqType value); //尾插元素，value是插入元素的值
void seqlistPopBack(seqlist *seq); //尾删元素，value是插入元素的值
void seqlistPushHead(seqlist*seq, seqType value); //头插元素
void seqlistPopHead(seqlist*seq); //头删元素
seqType seqlistFind(seqlist *seq, seqType data); //查找任意元素
seqType seqlistRead_pos(seqlist*seq, size_t pos); //读取任意位置的元素
size_t seqlistFind_pos(seqlist*seq, seqType value); //查找指定元素的下标
seqType seqlistModify(seqlist*seq, size_t pos, seqType data); //修改任意位置的元素

在进行插入、删除等操作中，若对元素的位置移动不清楚的借助画图能更好地理解。
