增加連絡人函數

void add_peo(pCon pcon)//增加儲存人函數{//判斷if(pcon->count==PEO_MAX){printf("儲存空間已滿\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++;}

刪除連絡人函數

void del_peo(pCon pcon)//刪除函數{char tmpName[NAME_MAX];int ret=0;printf("請輸入你所要刪除的姓名:>");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];//用後面的資料覆蓋所要刪除的資料}pcon->count--;//儲存人數減少一位}else{printf("找不到所要刪除的資訊\n");}}

尋找連絡人函數段

void search_peo(pCon pcon)//尋找函數{char tmpName[NAME_MAX];int ret=0;printf("請輸入你所要尋找的姓名:>");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("不存在所要尋找的資訊\n");}}

修改連絡人函數段

void modify_peo(pCon pcon)//修改資料函數{char tmpName[NAME_MAX];int ret=0;printf("請輸入你所要修改的姓名:>");scanf("%s",tmpName);ret = find(pcon,tmpName);if(-1 != ret)//找到修改姓名之後重新賦值{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);}}

顯示連絡人函數段

void show_peo(pCon pcon)//顯示函數{int i;for(i=0;i<pcon->count;i++) //顯示並列印說有連絡人資訊{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);}}

清空連絡人函數段

void clear_peo(pCon pcon)//清除所有連絡人資訊{pcon->count = 0;}
