SeqList 顺序表的静态实现

顺序表是C语言中一种基本的结构，可以存储各种基本类型的数据，而且不但可以存储基本类型的数据，也可以存储一种结构。一个顺序表应该具有的功能，头插，尾插，定点插入，排序等等都是一些最基本的功能，通过学习整理，下面来实现一下这些功能：

SeqList.h   //头文件

#ifndef __SEQLIST_H__
#define __SEQLIST_H__
#include <stdio.h>
#include <assert.h>
#include <string.h>

#define MAX 10   //容量

typedef int DataType; //定义数据类型 int类型重命名为DataType  

typedef struct SeqList
{
    DataType data[MAX];
    int sz;  //计数
}SeqList, *pSeqList;

void InitSeqList(pSeqList ps); //顺序表初始化
void PushBack(pSeqList ps, DataType d);  //尾部插入一个元素
void PopBack(pSeqList ps);  //头部插入一个元素
void Display(const pSeqList ps); //打印顺序表
void PushFront(pSeqList ps, DataType d);//尾部删除一个元素
void PopFront(pSeqList ps);//投头部删除一个元素
int Find(pSeqList ps, DataType d);//查找
void Insert(pSeqList ps, DataType d, int pos);//在给定位置插入一个元素
void Remove(pSeqList ps, DataType d);//删除顺序表中第一个出现的指定元素
void RemoveAll(pSeqList ps, DataType d);//删除顺序表中所有指定的元素
void Reverse(pSeqList ps);//逆序顺序表
void Sort(pSeqList ps);//排序
int BinarySearch(pSeqList ps, DataType d);//二分查找
#endif //__SEQLIST_H__

SeqList.c  //函数的实现

//#include <stdio.h>
#include "SeqList.h"
