单链表应用

本文主要是介绍单链表应用，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

基于单链表实现通讯录项目

//Contact.c
#define _CRT_SECURE_NO_WARNINGS 1
#include"contact.h"
#include"list.h"//初始化通讯录
void InitContact(contact** con)
{con = NULL;}
//添加通讯录数据
void AddContact(contact** con)
{PeoInfo info;printf("address:");scanf_s("%s", info.address, ADDR_MAX);printf("name:");scanf_s("%s", info.name, NAME_MAX);printf("sex:");scanf_s("%s", info.sex, SEX_MAX);printf("tel:");scanf_s("%s", info.tel, TEL_MAX);printf("age:");scanf_s("%d", &info.age);SLTPushBack(con, info);
}
//删除通讯录数据
void DelContact(contact** con)
{SListDesTroy(con);
}
//展示通讯录数据
void ShowContact(contact* con)
{SLTPrint(con);
}
//查找通讯录数据
void FindContact(contact* con)
{PeoInfo info;info.name[NAME_MAX];scanf_s("%s", info.name, NAME_MAX);printf("%p\n", SLTFind(con, info));
}
//修改通讯录数据
void ModifyContact(contact** con)
{PeoInfo info;info.name[NAME_MAX];scanf_s("%s", info.name, NAME_MAX);SLTNode* find = SLTFind(*con, info);if (find){printf("address:");scanf_s("%s", find->val.address, ADDR_MAX);printf("name:");scanf_s("%s", find->val.name, NAME_MAX);printf("sex:");scanf_s("%s", find->val.sex, SEX_MAX);printf("tel:");scanf_s("%s", find->val.tel, TEL_MAX);printf("age:");scanf_s("%d", &find->val.age);printf("修改完成\n");return;}else{printf("没找到");}
}
//销毁通讯录数据
void DestroyContact(contact** con)
{SListDesTroy(con);
}
