C语言实现静态顺序表的实例详解

线性表

定义一张顺序表也就是在内存中开辟一段连续的存储空间，并给它一个名字进行标识。只有定义了一个顺序表，才能利用该顺序表存放数据元素，也才能对该顺序表进行各种操作。

接下来看看静态的顺序表，直接上代码：

SeqList.h

#define _CRT_SECURE_NO_WARNINGS 1

#ifndef __SEQLIST_H__
#define __SEQLIST_H__

#include <stdio.h>
#include <stdlib.h>
#include <assert.h>
#include <string.h>

#define MAX 10

typedef int DataType;

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

void InitSeqList(pSeqList ps);
void PushBack(pSeqList ps, DataType d);
void PopBack(pSeqList ps);
void PushFront(pSeqList ps, DataType d);
void PopFront(pSeqList ps);
void Display(const pSeqList ps);
int Find(pSeqList ps, DataType d);
void Insert(pSeqList ps, DataType d, int pos);
void Remove(pSeqList ps, DataType d);
void RemoveAll(pSeqList ps, DataType d);
void Reverse(pSeqList ps);
void Sort(pSeqList ps);
int BinarySearch(pSeqList ps, DataType d);
