增加联系人函数

void add_peo(pCon pcon)//增加存储人函数{//判断if(pcon->count==PEO_MAX){printf("存储空间已满\n");return ;}printf("name:>");scanf("%s",(pcon->dhb[pcon->count]).name);printf("sex:>");scanf("%s",(pcon->dhb[pcon->count]).sex);printf("age:>");scanf("%d",&((pcon->dhb[pcon->count]).age));printf("tele:>");scanf("%s",(pcon->dhb[pcon->count]).tele);printf("addr:>");scanf("%s",(pcon->dhb[pcon->count]).addr);pcon->count++;}

删除联系人函数

void del_peo(pCon pcon)//删除函数{char tmpName[NAME_MAX];int ret=0;printf("请输入你所要删除的姓名:>");scanf("%s",tmpName);ret=find(pcon,tmpName);if(-1 != ret){int j=ret;for(;j<pcon->count-1;j++){pcon->dhb[j]=pcon->dhb[j+1];//用后面的数据覆盖所要删除的数据}pcon->count--;//存储人数减少一位}else{printf("找不到所要删除的信息\n");}}

查找联系人函数段

void search_peo(pCon pcon)//查找函数{char tmpName[NAME_MAX];int ret=0;printf("请输入你所要查找的姓名:>");scanf("%s",tmpName);ret = find(pcon,tmpName);if(ret != -1){printf("%s\t%s\t%d\t%s\t%s\t\n",pcon->dhb[ret].name,pcon->dhb[ret].sex,pcon->dhb[ret].age,pcon->dhb[ret].tele,pcon->dhb[ret].addr);}else{printf("不存在所要查找的信息\n");}}

修改联系人函数段

void modify_peo(pCon pcon)//修改数据函数{char tmpName[NAME_MAX];int ret=0;printf("请输入你所要修改的姓名:>");scanf("%s",tmpName);ret = find(pcon,tmpName);if(-1 != ret)//找到修改姓名之后重新赋值{printf("name:>");scanf("%s",(pcon->dhb[ret]).name);printf("sex:>");scanf("%s",(pcon->dhb[ret]).sex);printf("age:>");scanf("%d",&((pcon->dhb[ret]).age));printf("tele:>");scanf("%s",(pcon->dhb[ret]).tele);printf("addr:>");scanf("%s",(pcon->dhb[ret]).addr);}}

显示联系人函数段

void show_peo(pCon pcon)//显示函数{int i;for(i=0;i<pcon->count;i++) //显示并打印说有联系人信息{printf("%s\t%s\t%d\t%s\t%s\t\n",pcon->dhb[i].name,pcon->dhb[i].sex,pcon->dhb[i].age,pcon->dhb[i].tele,pcon->dhb[i].addr);}}

清空联系人函数段

void clear_peo(pCon pcon)//清除所有联系人信息{pcon->count = 0;}
