一、顺序表的创建、删除和插入#define _crt_secure_no_warnings 1#includestruct sqlist {int date[10];in...

一、顺序表的创建、删除和插入

#define _crt_secure_no_warnings 1
#include<stdio.h>
struct sqlist {
	int date[10];
	int length;
};
void initlist(sqlist& l) {
	for (int i = 0;i < 10;i++) {
		l.date[i] = 0;
	}
	l.length = 0;
}
void charu(sqlist& l) {
	for (int j = 0;j < 5;j++) {
		scanf("%d", &l.date[j]);
		l.length++;
	}
}
void listinsert(sqlist& l, int i, int e) {
	for (int k = l.length;k >= i;k--) {
		l.date[k] = l.date[k - 1];
	}
	l.date[i - 1] = e;
	l.length++;
}
void print(sqlist& l) {
	for (int i = 0;i < l.length;i++) {
		printf("%d ", l.date[i]);
	}
	printf("\n");
}
void listdelete(sqlist& l, int i, int e) {
	for (int j = i;j < l.length;j++) {
		l.date[j-1] = l.date[j];
	}
	l.length--;
}
int main() {
	sqlist l;//创建顺序表l
	initlist(l);//初始化顺序表
	shuru(l);//输入值
	listinsert(l, 3, 3);//插入值
	print(l);//打印
	listdelete(l, 3, 3);//删除值
	print(l);
	return 0;
}

以上操作分别实现了对顺序表的创建,插入,删除和打印

二、单链表的创建、删除、增加和输出

#define _crt_secure_no_warnings 1
#include<stdio.h>
#include<stdlib.h>
struct listnode {
    int num;
    struct listnode* next;
};
struct listnode* create(struct listnode* head) {
    struct listnode * p1, * p2;
    p1 = p2 = (struct listnode*)malloc(sizeof(struct listnode));
    scanf("%d", &p1->num);
    while (p1->num!=0){
        if (head == null) {
            head = p1;
        }
        else {
            p2->next = p1;
        }
        p2 = p1;
        p1= (struct listnode*)malloc(sizeof(struct listnode));
        scanf("%d", &p1->num);
    }
    p2->next = null;
    free(p1);
    return head;
}
void print(struct listnode* head) {
    while (head != null) {
        printf("%d ", head->num);
        head = head->next;
    }
}
int main() {
    struct listnode* head=null;
    head=create(head);//创建链表
    print(head);//输出链表
	return 0;
}

以上操作为创建链表并打印,效果如下:

现在增加插入操作

#define _crt_secure_no_warnings 1
#include<stdio.h>
#include<stdlib.h>
struct listnode {
    int num;
    struct listnode* next;
};
struct listnode* create(struct listnode* head) {
    struct listnode * p1, * p2;
    p1 = p2 = (struct listnode*)malloc(sizeof(struct listnode));
    scanf("%d", &p1->num);
    while (p1->num!=0){
        if (head == null) {
            head = p1;
        }
        else {
            p2->next = p1;
        }
        p2 = p1;
        p1= (struct listnode*)malloc(sizeof(struct listnode));
        scanf("%d", &p1->num);
    }
    p2->next = null;
    free(p1);
    return head;
}
void print(struct listnode* head) {
    while (head != null) {
        printf("%d ", head->num);
        head = head->next;
    }
    printf("\n");
}
struct listnode* insert(struct listnode* head,int i) {
    struct listnode* p1,*p2,*p;
    p1 =p2= head;
    for (int j = 1;j < i;j++) {
        p2 = p1;
        p1 = p1->next;
    }
    p= (struct listnode*)malloc(sizeof(struct listnode));
    printf("请输入插入的数:");
    scanf("%d", &p->num);
    p2->next = p;
    p->next = p1;
    return head;
}
int main() {
    struct listnode* head=null;
    int a, b;
    head=create(head);
    print(head);
    printf("请输入插入位置:");
    scanf("%d", &a);
    head = insert(head,a);//插入新数据
    print(head);
	return 0;
}

效果如下:

现增加删除操作

#define _crt_secure_no_warnings 1
#include<stdio.h>
#include<stdlib.h>
struct listnode {
    int num;
    struct listnode* next;
};
struct listnode* create(struct listnode* head) {
    struct listnode * p1, * p2;
    p1 = p2 = (struct listnode*)malloc(sizeof(struct listnode));
    scanf("%d", &p1->num);
    while (p1->num!=0){
        if (head == null) {
            head = p1;
        }
        else {
            p2->next = p1;
        }
        p2 = p1;
        p1= (struct listnode*)malloc(sizeof(struct listnode));
        scanf("%d", &p1->num);
    }
    p2->next = null;
    free(p1);
    return head;
}
void print(struct listnode* head) {
    while (head != null) {
        printf("%d ", head->num);
        head = head->next;
    }
    printf("\n");
}
struct listnode* insert(struct listnode* head,int i) {
    struct listnode* p1,*p2,*p;
    p1 =p2= head;
    for (int j = 1;j < i;j++) {
        p2 = p1;
        p1 = p1->next;
    }
    p= (struct listnode*)malloc(sizeof(struct listnode));
    printf("请输入插入的数:");
    scanf("%d", &p->num);
    p2->next = p;
    p->next = p1;
    return head;
}
struct listnode* delete(struct listnode* head, int i) {
    struct listnode* p1, * p2;
    p1 = p2 = head;
    while (p1!=null&&p1->num != i) {
        p2 = p1;
        p1 = p1->next;
    }
    if (p1 == head) {
        head = head->next;
    }
    else {
        p2->next = p1->next;
    }
    return head;
}
int main() {
    struct listnode* head=null;
    int a, b;
    head=create(head);
    print(head);
    printf("请输入插入位置:");
    scanf("%d", &a);
    head = insert(head,a);
    print(head);
    printf("请输入删除值:");
    scanf("%d", &b);
    head = delete(head, b);//删除数据
    print(head);
	return 0;
}

效果如下:

C语言数据结构之顺序表和单链表

因此,我们便实现了对单链表的创建、删除、增加和输出
