1. 數(shù)組(存儲):

• 靜態(tài)數(shù)組
• 動態(tài)int* parr=calloc(size,sizeof(type));

2. 容量：capacity
3. 有效元素個數(shù)：size

2.定義

typedef int Elementtype;   //ADT抽象數(shù)據(jù)類型
typedef struct seqlist
{int capacity;          //容量
    int size;              //有效元素個數(shù)
    Elementtype* data;     //定義數(shù)組指針
}seqlest;

3.斷言

#include
assert(...);   //斷言...為真，如果不為真，則會中斷程序

4.初始化

//法一：
void seqlist_init(seqlist* list)
{list->size = 0;
	list->capacity = 8;
	list->data = calloc(list->capacity,sizeof(Elementtype));
	if (!list->data)
	{assert(list->data);
	}
}

//法二：
seqlist* seqlist_creat()
{seqlist* list = calloc(1, sizeof(seqlist));
	if(!list)
	{assert(list);
	}
	seqlist_init(list);
	return list;
}

void seqlist_destory(seqlist* list)
{//先釋放數(shù)組
	free(list->data);
	//再釋放順序表
	if (list)
	{free(list);
	}
}

5.元素的插入 1.尾插

//尾插
void seqlist_pushback(seqlist* list, Elementtype val)
{if(seqlist_full(list))
	{printf("seqlist is full , can't insert ! \n");
		return;
	}
	list->data[list->size++] = val;
}

2.頭插

//頭插
void seqlist_pushfront(seqlist* list, Elementtype val)
{if (seqlist_full(list))
	{printf("seqlist is full , can't insert !\n");
		return;
	}
	//先移動后面的元素，為新插入的元素的元素的騰出空間
	for ( int i = list->size; i >0 ; i--)
	{list->data[i] = list->data[i - 1];
	}
	//插入新元素
	list->data[0] = val;
	list->size++;
}

3.任意插

//任意插
void seqlist_insert(seqlist* list, int pos, Elementtype val)
{if (seqlist_full(list))
	{printf("seqlist is full , can't insert !\n");
		return;
	}
	//判斷pos是否合法
	if( pos< 0 || pos >list->size )
	{pos = list->size;
	}
	//移動
	for ( int i = list->size ; i >pos ; i--)
	{list->data[i] = list->data[i - 1];
	}
	list->data[pos] = val;
	list->size++;
}

6.元素的刪除 1.尾刪

//尾刪
void seqlist_popback(seqlist* list)
{if(seqlist_empty(list))
	{printf("seqlist is emoty , can't delete !\n");
		return;
	}
	list->size--;
}

2.頭刪

//頭刪
void seqlist_popfront(seqlist* list)
{if (seqlist_empty(list))
	{printf("seqlist is emoty , can't delete !\n");
		return;
	}
	for ( int i = 0; i< list->size-1; i++)
	{list->data[i] = list->data[i + 1];
	}
	list->size--;
}

3.查找

//查找
int seqlist_find(seqlist* list, Elementtype val)
{for (int i = 0; i< list->size; i++)
	{if (list->data[i] == val)
		{	return i;
		}
	}
	return -1;
}

4.指定刪(元素)

//指定刪(元素)
void seqlist_removeOne(seqlist* list, Elementtype val)
{if (seqlist_empty(list))
	{printf("seqlist is emoty , can't delete !\n");
		return;
	}
	if(seqlist_find(list,val))
	{for (int j = seqlist_find(list, val); j< list->size - 1; j++)
		{	list->data[j] = list->data[j + 1];
		}
	}
	list->size--;
}

5.指定位置刪除

//指定位置刪除
void seqlist_removePos(seqlist* list, int pos)
{if (seqlist_empty(list))
	{printf("seqlist is emoty , can't delete !\n");
		return;
	}
	assert(pos >0 && pos< list->size);
	for (int i = pos; i< list->size-1 ; i++)
	{list->data[i] = list->data[i + 1];
	}
	list->size--;
}

7.擴容

bool inc(seqlist* list)
{seqlist* newlist = realloc(list->data, list->capacity + list->capacity * 2, sizeof(Elementtype));
	if( !newlist )
	{return false;
	}
	list->data = newlist;
	list->capacity += list->capacity * 2;
	return true;
}
