线性表和单链表的问题

主要实验内容：

1、 建立一个顺序存储的线性表，实现线性表的插入、删除操作

2、 建立一个单链表，实现单链表的插入、删除操作

要求：

（1）建立一个按关键字有序的线性表，从键盘上输入一个数，将该数插入到表中，使该线性表插入数据后仍按关键字有序

（2）建立一个线性表，从键盘上输入一个数，查找表中是否存在该数，若有则删除所有与该数相等的数。

C/C++都可以~

测试通过后给300分，帮帮忙~

第一个，我把以前写过的代码搬了过来，用的是数组，关键字就是元素本身的大小：

#include <stdio.h>

int* binary_search( int* beg, int* end, int val )
{
int* mid;
while( beg < end ) {
mid = beg + ( (end - beg) >> 1 );
if( *mid == val )
return mid;
else if( *mid < val )
beg = mid + 1;
else
end = mid;
}
return beg;
}

int main()
{
int a[] = { 1,1,2,3,5,5,6,7,8,9,-1 };
int b, *p, *q;

for( p = a; *p != -1; ++p )
printf( "%d ", *p );

putchar( '\n' );
scanf( "%d", &b );
p = binary_search( a, a + 10, b );
for( q = a + 10; q != p; --q )
*q = q[-1];
*p = b;
for( p = a; p != a + 11; ++p )
printf( "%d ", *p );
return 0;
}


第二个，单链表查找删除：

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

typedef struct _list {
int val;
struct _list* next;
} *node, list;

node Insert( node* head, node pos, int val )
{
node tmp;
tmp = ( node )malloc( sizeof( list ) );
tmp->val = val;
tmp->next = pos ? pos->next : *head;
if ( pos ) {
pos->next = tmp;
} else {
*head = tmp;
}
return tmp;
}

node Find( node head, int n ) {
if ( !head )
return NULL;
while ( head && head->val != n ) {
head = head->next;
}
return head;
}

node Create( int* beg, int* end )
{
node head, t;
head = t = NULL;
while ( beg != end ) {
t = Insert( &head, t, *beg++ );
}
return head;
}

void Remove( node* head, node n )
{
node prev, next;
prev = next = *head;
while ( next != n ) {
prev = next;
next = next->next;
}
if ( prev == *head ) {
*head = next->next;
} else {
prev->next = next->next;
}
free( next );
}

void Print( node head )
{
while ( head ) {
printf( "%d ", head->val );
head = head->next;
}
putchar( '\n' );
}


int main()
{
int a[] = { 6,1,3,9,2,8,5,0,7,4 };
int n;
node head, pos;
head = Create( a, a + 10 );
Print( head );
printf( "plz enter a num:" );
scanf( "%d", &n );

while( ( pos = Find( head, n ) ) != NULL ) {
Remove( &head, pos );
}
printf( "after delete all node with value %d:\n", n );
Print( head );
return 0;
}

给你个链表的操作吧

#include<stdio.h> #include<stdlib.h> #define MAX 20 #define ELEMTP int

#define v (*p)

struct node { ELEMTP data; struct node *next; };

struct node *p,*q,*s,*head; int j=0,i,k; void main() { int x,y,cord; void outlin(struct node *h); void create(); void insert(struct node *h,int x,int y); void deletes(struct node *h,int x); struct node *MaxCompare(struct node *h); struct node *MinCompare(struct node *h); int delIterance(struct node *h); void batchInsert(struct node *h,int x); void batchDelete(struct node *h,int x,int y); void Cz(struct node* h); void Xg(struct node * h); printf("建立链表，输入-999完成链表: \n"); create(); i=j; outlin(head); do{ printf("\n 主菜单 \n"); printf(" 1 插入一个元素 \n"); printf(" 2 删除一个元素 \n"); printf(" 3 升序排序 \n"); printf(" 4 降序排序 \n"); printf(" 5 查找元素 \n"); printf(" 6 修改元素 \n"); printf(" 7 删除重复元素 \n"); printf(" 8 批量加入元素 \n"); printf(" 9 批量删除元素 \n"); printf(" 0 结束程序运行 \n"); printf("-----------------------------------------\n"); printf(" 请输入您的选择(1, 2, 3, 4, 5, 6, 7, 8, 9, 0) "); scanf("%d",&cord); switch(cord) { case 1: { printf("请输入插入的位置 i: "); scanf("%d",&x); printf("请输入插入的数据 y: "); scanf("%d",&y); insert(head,x,y); i=j; outlin(head); }break; case 2: { printf("x=?"); scanf("%d",&x); deletes(head,x); i=j; outlin(head); }break; case 4: { printf("链表由大到小是"); s=MaxCompare(head); j=i; outlin(s); //outlin(head); }break; case 3: { printf("链表由小到大是"); s=MinCompare(head); j=i; outlin(s); }break; case 5: { Cz(head); outlin(head); }break; case 6: { Xg(head); outlin(head); }break; case 7: { k=delIterance(head); i=i-k; j=i; outlin(head); }break; case 8: { printf("请输入插入的位置 i: "); scanf("%d",&x); batchInsert(head,x); i=j; outlin(head); }break; case 9: { printf("请输入删除的起始位置 i: "); scanf("%d",&x); printf("请输入删除的结束位置 y: "); scanf("%d",&y); batchDelete(head,x,y); i=j; outlin(head); }break; case 0: { exit(0); }break; } }while(cord<=9&&cord>=0); }

void outlin(struct node *h) { p=h->next; while(p!=NULL) { printf(" data=%4d ",p->data); p=p->next; } printf("\n输出结束\n\n"); }

void deletes(struct node *h,int x)//删除节点 { p=h; while(p->next!=NULL&&p->next->data!=x) p=p->next; if(p->next==NULL) printf("x 不存在 !"); else { q=p->next; p->next=q->next; free(q); --j; }

}

void insert(struct node *h,int x,int y) { s=(struct node*)malloc(sizeof(struct node)); s->data=y; q=h;p=h->next; while(p!=NULL&&p->data!=x) { q=p; p=p->next; } q->next=s; s->next=p; ++j; }

void create()//建立链表 { int x; head=(struct node*)malloc(sizeof(struct node)); head->next=NULL; p=head; printf("x=?"); scanf("%d",&x); while(x!=-999) { s=(struct node*)malloc(sizeof(struct node)); s->data=x; s->next=NULL; p->next=s; p=s; printf("x=?");++j; scanf("%d",&x); } }
