动态顺序表能够根据数据存储的需要动态地管理内存空间。

SeqList.h

#include<stdio.h>
#include<stdlib.h>//静态顺序表
//小了不够用，多了浪费
//#define N 10
//typedef int SLDatatype;
//struct SeqList
//{
//	SLDatatype a[N];
//	int size;
//
//};typedef int SLDatatype;
typedef struct SeqList
{SLDatatype* a;int size;//数据个数int capacity;//容量
}SL;
void SLInit(SL* psl);
void SLDestory(SL* psl);
void SLPrint(SL* psl);
void SLPushBack(SL* psl, SLDatatype x);
void SLPushFront(SL* psl, SLDatatype x);
void SLPopBack(SL* psl);
void SLPopBack(SL* psl);

SeqList.c

#include"SeqList.h"void SLInit(SL *psl) {psl->a = (SLDatatype*)malloc(sizeof(SLDatatype) * 4);if (psl->a == NULL) {perror("malloc fail");return 0;}psl->capacity = 4;psl->size = 0;

Test.c

#include"SeqList.h"
int main() {SL s;SLInit(&s);SLPushBack(&s, 1);SLPushBack(&s, 2);SLPushBack(&s, 3);SLPushBack(&s, 4);SLPushBack(&s, 5);SLPushBack(&s, 6);SLPushBack(&s, 6);SLPushBack(&s, 6);SLPushBack(&s, 6);SLPrint(&s);SLDestory(&s);return 0;
