c語言號碼
1. c語言製作簡單的通訊錄

2. 怎麼給C語言中的字元串編號。
抽象一點，比如一個字元串100字元，內存地址+（編號*100）就是字元串地址了。
3. c語言中的|號表示什麼意思
a|b 就是把整數a b都轉換成2進制，然後右對齊寫出來，兩個都是0就是0，否則是1。
4. c語言通訊錄代碼

5. C語言編寫一個簡短的通訊錄，輸入聯系人得知電話號碼和性別等基本信息就可以，謝謝！
我重寫一個哦
classtongxunlu{
stringa;
stringb;
stringc;
}
tongxunlumyfriend[2];
cin>>myfriend[0].a>>myfriend[0].b>>myfriend[0].c;//給我的朋友賦值，就是添加信息
cout<<myfriend[0].a<<myfriend[0].b<<myfriend[0].c;//輸出這就是給他注入信息然後在取出來個過程，注釋寫得很詳細，根據你的需要自己修改吧，這個是我以前回答別人的時候寫的
6. c語言對號碼的添加和刪除
保存一堆的號碼？
可以用鏈表。 去看看stl中的list
7. C語言，翻譯電話號碼
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
#include<conio.h>
charwords[11][8]={"zero","one","two","three","four","five","six","seven","eight","nine","double"};
intwordslen[11];
intstate;//1double過的0沒有過的
chartext1[1000];
chartext[1000];
charresult[100];
voidsetlen()
{
intn;
for(n=0;n<11;n++)
{
wordslen[n]=strlen(words[n]);
}
}
voidzhengli()
{
intl,n;
charc;
intnt=0;
l=strlen(text1);
for(n=0;n<l;n++)
{
c=text1[n];
if(c>='a'&&c<='z')
{
text[nt++]=c;
}
elseif(c>='A'&&c<='Z')
{
c+=('a'-'A');
text[nt++]=c;
}
text[nt]=' ';
}
}
voidzhuanhua()
{
intl,n,r;
intnr=0;
intnnow=0;//目前到了哪個位。
chartt[8];
l=strlen(text);
while(nnow<l)
{
r=-1;
strncpy(tt,&text[nnow],7);
//printf("提取的段式%s ",tt);
for(n=0;n<11;n++)
{
//printf("跟%s比較 ",words[n]);
if(strncmp(tt,(char*)words[n],wordslen[n])==0)
{
r=n;
nnow+=wordslen[n];
break;
}
}
if(r==-1)
{
printf("ERROR. ");
nnow++;
}
if(n>9)
{
state=1;
}
else
{
if(state==1)
{
result[nr++]='0'+r;
state=0;
}
result[nr++]='0'+r;
}
}
result[nr++]=' ';
printf("結果%s",result);
}
intmain()
{
setlen();
printf("輸入要轉換的字元串，敲鍵盤或右鍵粘貼:");
scanf("%s",text1);
zhengli();//小寫化，去空格，去連接符
zhuanhua();
getch();
return0;
}
8. 關於c語言判斷電話號碼合法問題
#include <stdio.h>
main(){
char phone[15];
int i,flag=0;
int n_digi=0, right_n_digi=9;
printf("please input telephone number\n");
gets(phone);
// 判斷 是否是 數字 和 減號：
for (i=0;i<strlen(phone);i++){
if (phone[i] != '-' && ( phone[i]>'9' || phone[i] < '0')) flag = 1;
}
if (flag==1) printf("wrong number\n"); else printf("may right number\n");
// 根據需要，還可以加別的條件判斷：
// 例如 總長度判斷，例如 必須有 9 個數字:
if (flag==0)
{
for (i=0;i<strlen(phone);i++) { if (phone[i]<='9' && phone[i] >= '0') n_digi++;};
if (n_digi != right_n_digi) printf("wrong number\n"); else printf("may right number\n");
}
return 0;
}
9. 怎麼用C語言實現電話號碼的匹配。
可以看下正則表達式。
