【C语言习题】用程序实现“顺序表”的以下 *** 作：初始化、取值、查找、插入、删除、清空、退出...

题目内容：

用程序实现“顺序表”的以下 *** 作：

①初始化、取值、查找、插入、删除、清空、退出...——存为“头文件”；

②主函数调用以上 *** 作——用switch。

个人解法如下：

1.自定义的头文件

#include
#define Maxsize 100
#define Succeed 1
#define Error 0
#define Overflow -1
 
typedef int Status;
typedef int ElemType;

typedef struct
{
	int* elem;
	int length;
}SqList;
 
Status InitList_Sq(SqList& L)
{
	L.elem = (int*)malloc(sizeof(int) * Maxsize);
	if (!L.elem)
		return Overflow;
	L.length = 0;
	return Succeed;
}
 
Status GetElem_Sq(SqList& L, int i, ElemType e)
{
	if (i<1 || i>L.length)
		return Error;
	e = L.elem[i - 1];
		return Succeed;
}

Status ListInsert_Sq(SqList& L, int i, ElemType e)
{
	if (i<1 || i>L.length+1)
		return Error;
	if (L.length == Maxsize)
		return Overflow;
	for (int j = L.length - 1; j >= i - 1; j--)
		L.elem[j + 1] = L.elem[j];
	L.elem[i - 1] = e;
	++L.length;
		return Succeed;
}

Status ListDelete_Sq(SqList& L, int i)
{
	if (i<1 || i>L.length)
		return Error;
	if (L.length == Maxsize)
		return Overflow;
	for (int j = i - 1; j < L.length - 1; j++)
		L.elem[j] = L.elem[j + 1];
	--L.length;
	return Succeed;
}

int LocateElem_Sq(SqList& L, ElemType e)
{
	for (int i = 0; i < L.length; i++)
		if (L.elem[i] == e)
			return i + 1;
	return 0;
}

void CreateList_Sq(SqList& L)
{
	int n, i;
	printf("\n请输入数据元素个数:");
	scanf("%d", &n);
	printf("\n请输入%d个数据元素:\n", n);
	for (int i = 0; i < n; i++)
	{
		scanf("%d", &L.elem[i]);
		L.length++;
	}
}
 
void PrintList_Sq(SqList& L)
{
	if (!L.elem)
		printf("\n顺序表不存在!");
	else if (L.length)
	{
		printf("\n该顺序表的元素有:\n");
		for (int i = 0; i < L.length; i++)
			printf("%d\n", L.elem[i]);
	}
	else
		printf("\n顺序表不存在!");
}
 
void DestroyList_Sq(SqList& L)
{
	if (L.elem)
		free(L.elem);
	L.elem = NULL;
}
 
void ClearList_Sq(SqList& L)
{
	L.length = 0;
}

2.主文件（注意主文件内调用的头文件名须与自定义的头文件名相同）

#define _CRT_SECURE_NO_WARNINGS //防报错
#include
#include"SqList.h"

int main()
{
	system("color 3");
	SqList TargetList;
	ElemType Value;
	int Location, Location2, Choice;
	if (InitList_Sq(TargetList) == Succeed)
	{
		printf("顺序表初始化成功!\n");
		while (1)
		{
			system("cls");
			printf("0--------结束\n");
			printf("1--------创建\n");
			printf("2--------显示\n");
			printf("3--------取值\n");
			printf("4--------查找\n");
			printf("5--------插入\n");
			printf("6--------删除\n");
			printf("7--------清空\n");
			printf("8--------销毁\n");
			printf("\n请选择你所需要的 *** 作项:\n");
			scanf("%d", &Choice);
			switch (Choice)
			{
			case 0:
				exit(0);
			case 1:
				CreateList_Sq(TargetList);
			case 2:
				PrintList_Sq(TargetList);
			case 3:
				printf("\n请输入欲获取的元素的位置:\n");
				scanf("%d", &Location);
				if (GetElem_Sq(TargetList, Location, Value) == Succeed)
					printf("获取的元素的值为:%d\n", Value);
				else
					printf("获取失败，请检查输入的元素的位置!\n");
				break;
			case 4:
				printf("\n请输入欲查找的元素的值:\n");
				scanf("%d", &Value);
				if (Location2 = LocateElem_Sq(TargetList, Value))
					printf("查找的元素的位置为:%d\n", Location2);
				else
					printf("查找失败，请检查输入的元素的值!\n");
				break;
			case 5:
				printf("\n请输入欲插入的元素的值:\n");
				scanf("%d", &Value);
				printf("请输入欲插入的元素的位置:\n");
				scanf("%d", &Location);
				if (GetElem_Sq(TargetList, Location, Value) == Succeed)
					PrintList_Sq(TargetList);
				else
					printf("插入失败，请检查输入的元素的位置!\n");
				break;
			case 6:
				printf("\n请输入欲删除的元素的位置:\n");
				scanf("%d", &Location);
				if (ListDelete_Sq(TargetList, Location) == Succeed)
					PrintList_Sq(TargetList);
				else
					printf("删除失败，请检查输入的元素的位置!\n");
				break;
			case 7:
				DestroyList_Sq(TargetList);
			case 8:
				ClearList_Sq(TargetList);
			default:
				printf(" *** 作项不存在，请重新选择!\n"); 
			}system("pause");
		}
		printf("缓存已被清除!\n");
	}
	else
		printf("顺序表初始化失败!\n");
	return 0;
}

运行结果：

本人拙作，请大佬们点评。
