C语言实现通讯录的示例代码

一、contact.h文件

包含函数的声明

#pragma once
#define _crt_secure_no_warnings 1
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <assert.h>

#define max 100
#define max_name 20
#define max_sex 10
#define max_tele 20
#define max_addr 30
#define max_leg 5

//结构体的定义，用于储存通讯录数据
struct contact
{
	char name[max_name];
	char sex[max_sex];
	char tele[max_tele];
	char addr[max_addr];
	int age;
};

struct peoinfo
{
	struct contact* data;
	int length;
	int capacity;
};

//定义游戏菜单函数
void menu();

//定义初始结构体函数
void initcontact(struct peoinfo* abs);

//添加通讯录消息函数的声明
void addconinfo(struct peoinfo* abs);

//查询信息是否存在函数
int isexist(struct peoinfo* abs, char* name);

//删除指定信息函数的定义
void delconinfo(struct peoinfo* abs);

//修改指定信息函数的定义
void modefiinfo(struct peoinfo* abs);

//查询指定信息函数的定义
void searchinfo(struct peoinfo* abs);

//展示通讯录信息函数的定义
void showinfo(struct peoinfo* abs);

//清空通讯录列表函数的定义
void clearinfo(struct peoinfo* abs);

//排序通讯录信息函数的定义
void sortinfo(struct peoinfo* abs);

//扩容函数的定义
int incmemmery(struct peoinfo* abs);

二、contact.c文件

包含函数的实现

#include "contact.h";



//游戏菜单函数的实现
void menu()
{
	printf("***********************************\n");
	printf("*******1.add          2.del********\n");
	printf("*******3.modefi       4.search*****\n");
	printf("*******5.show         6.clear******\n");
	printf("*******7.sort         0.exit*******\n");
	printf("***********************************\n");
}


//扩容函数的实现
int incmemmery(struct peoinfo* abs)
{
	struct contact* ptr = (struct contact*)realloc(abs->data, (abs->capacity + 3) * sizeof(struct contact));
	if (ptr == null)
	{
		perror("getmemmery():");
		return -1;
	}
	else
	{
		abs->data = ptr;
		abs->capacity += 3;
		return 1;
	}
}

//初始化通讯录函数的实现
void loadinfo(struct peoinfo* abs)
{
	file* pf;
	pf = fopen("contact.txt", "rb");
	if (pf == null)
	{
		perror("initcontact():");
		return;
	}
	struct contact tmp = { 0 };
	while (fread(&tmp, sizeof(struct contact), 1, pf))
	{
		if (abs->length == abs->capacity)
		{
			incmemmery(abs);
		}
		*(abs->data + abs->length) = tmp;
		abs->length++;
	}
	fclose(pf);
	pf == null;
}

void initcontact(struct peoinfo* abs)
{
	assert(abs);
	abs->length = 0;
	abs->data = (struct contact*)malloc(max_leg * sizeof(struct contact));
	abs->capacity = max_leg;
	loadinfo(abs);
}

//查询信息是否存在函数的实现
int isexist(struct peoinfo* abs, char* name)
{
	for (int i = 0; i < abs->length; i++)
	{
		if (strcmp(abs->data[i].name, name) == 0)
		{
			return i;
		}
	}
	return -1;
}

//添加通讯录消息函数的实现
void addconinfo(struct peoinfo* abs)
{
	assert(abs);
	if (abs->capacity == abs->length)
	{
		int ret  = incmemmery(abs);
		if (ret == 1)
		{
			printf("扩容成功！\n");
		}
		else
		{
			printf("扩容失败，内存不足！\n");
			return;
		}
	}
	
	printf("请输入添加的姓名：>");
	scanf("%s", abs->data[abs->length].name);
	printf("请输入添加的姓别：>");
	scanf("%s", abs->data[abs->length].sex);
	printf("请输入添加的联系方式：>");
	scanf("%s", abs->data[abs->length].tele);
	printf("请输入添加的住址：>");
	scanf("%s", abs->data[abs->length].addr);
	printf("请输入添加的年龄：>");
	scanf("%d", &(abs->data[abs->length].age));

	abs->length++;
	printf("已成功添加联系人！\n");
}

//删除指定信息函数的实现
void delconinfo(struct peoinfo* abs)
{
	assert(abs);
	char name[max_name];
	printf("请输入要删除通讯录的姓名：>");
	scanf("%s", name);
	int ret = isexist(abs, name);
	if (ret == -1)
	{
		printf("不存在此联系人！\n");
	}
	else
	{
		for (int i = ret; i < abs->length; i++)
		{
			abs->data[i] = abs->data[i + 1];
		}
		abs->length--;
	}
}

//修改制定信息函数的实现
void modefiinfo(struct peoinfo* abs)
{
	char name[max_name];
	printf("请输入要修改通讯录信息的姓名：>");
	scanf("%s", name);
	int ret = isexist(abs, name);
	if (ret == -1)
	{
		printf("要修改指定联系人不存在！\n");
	}
	else
	{
		printf("请输入要修改的姓名：>");
		scanf("%s", abs->data[ret].name);
		printf("请输入要修改的性别：>");
		scanf("%s", abs->data[ret].sex);
		printf("请输入要修改的联系方式：>");
		scanf("%s", abs->data[ret].tele);
		printf("请输入要修改的住址：>");
		scanf("%s", abs->data[ret].addr);
		printf("请输入要修改的年龄：>");
		scanf("%d", &(abs->data[ret].age));

		printf("修改成功！\n");

	}
}

//查询指定信息函数的实现
void searchinfo(struct peoinfo* abs)
{
	assert(abs);
	char name[max_name];
	printf("请输入要查询通讯录的姓名：>");
	scanf("%s", name);
	int ret = isexist(abs, name);
	if (ret == -1)
	{
		printf("要查找的信息不存在！");
	}
	else
	{
		printf("%-20s\t%-10s\t%-20s\t%-20s\t%-10s\n","姓名","性别","联系方式","住址","年龄");
		printf("%-20s\t%-10s\t%-20s\t%-20s\t%-10d\n",
			abs->data[ret].name,
			abs->data[ret].sex,
			abs->data[ret].tele,
			abs->data[ret].addr,
			abs->data[ret].age);

		printf("查询成功！\n");
	}
	
}

//展示通讯录信息函数的实现
void showinfo(struct peoinfo* abs)
{
	assert(abs);
	printf("%-20s\t%-10s\t%-20s\t%-20s\t%-10s\n", "姓名", "性别", "联系方式", "住址", "年龄");
	for (int i = 0; i < abs->length; i++)
	{
		printf("%-20s\t%-10s\t%-20s\t%-20s\t%-10d\n",
			abs->data[i].name,
			abs->data[i].sex,
			abs->data[i].tele,
			abs->data[i].addr,
			abs->data[i].age);
	}
}

//清空通讯录列表函数的实现
void clearinfo(struct peoinfo* abs)
{
	assert(abs);
	struct contact* ptr = (struct contact*)realloc(abs->data, max_leg * (sizeof(struct contact)));
	if (ptr == null)
	{
		perror("clearinfo():");
	}
	else
	{
		abs->length = 0;
		abs->data = ptr;
		memset(abs->data, 0, max_leg * sizeof(struct contact));
		abs->capacity = max_leg;
		printf("清空通讯录成功！\n");
	}
}


//排序通讯录函数的实现
int cmpbyage(const void* e1, const void* e2)
{
	return ((struct contact*)e1)->age - ((struct contact*)e2)->age;
}

int cmpbyname(const void* e1, const void* e2)
{
	return strcmp(((struct contact*)e1)->name, ((struct contact*)e2)->name);
}

void sortinfo(struct peoinfo* abs)
{
	getchar();
	char ch;
	printf("请输入排序的方式:>n(姓名)、a(年龄)，n or a：>");
	ch = getchar();
	if (ch == 'a')
	{
		qsort(abs->data, abs->length, sizeof(struct contact), cmpbyage);
		printf("已按照年龄排序成功！\n");
	}
	else if(ch == 'n')
	{
		qsort(abs->data, abs->length, sizeof(struct contact), cmpbyname);
		printf("已按照姓名排序成功！\n");
	}
	else
	{
		printf("输入错误！\n");
	}
}

//释放内存函数的实现
void freeinfo(struct peoinfo* abs)
{
	free(abs->data);
	abs->data = null;
}


//保存通讯录函数的实现
void saveinfo(struct peoinfo* abs)
{
	file* pf;
	pf = fopen("contact.txt", "wb");
	if (pf == null)
	{
		perror("saveinfo():");
		return;
	}
	for (int i = 0; i < abs->length; i++)
	{
		fwrite(abs->data + i, sizeof(struct contact), 1, pf);
	}
	fclose(pf);
	pf = null;
}

三、test.c文件

包含主函数即代码思想

#include "contact.h";

int main()
{
	int input = 0;
	struct peoinfo con;
	//初始化结构体
	initcontact(&con);
	do
	{
		menu();
		printf("请选择：>");
		scanf("%d", &input);
		switch (input)
		{
		case 1:
			addconinfo(&con);
			break;
		case 2:
			delconinfo(&con);
			break;
		case 3:
			modefiinfo(&con);
			break;
		case 4:
			searchinfo(&con);
			break;
		case 5:
			showinfo(&con);
			break;
		case 6:
			clearinfo(&con);
			break;
		case 7:
			sortinfo(&con);
			break;
		case 0:
			saveinfo(&con);
			freeinfo(&con);
			printf("退出通讯录！");
			break;
		default:
			printf("选择错误！\n");
		}
	} while (input);
	return 0;
}
