获取"11，22，33；44，55，66；77，88，99"字符串中被“，”号隔开的每一个字符串

\#include<string.h>

\#include<stdio.h>  
void main()  
\{  
    char quick\_dial\_code\[64\]=\{0\};  
    char vanity\[32\]=\{0\};  
    char path\[64\]="11,22,33;44,55,66;77,88,99";  
    char number\[64\] = \{0\};  
    char \*p = NULL;  
    char \*q = NULL;  
    char \*m = NULL;

char phone\_list\[64\] = \{0\};

m=strtok(path, ";");  
    while(m != NULL)  
    \{  
        strncpy(phone\_list, m, 64);  
        p= strstr(phone\_list, ",");  
       if(p!=NULL)  
       \{  
           strncpy(quick\_dial\_code, phone\_list, p-phone\_list);  
           printf("quick\_dial\_code=%s\\n",quick\_dial\_code);  
           q=strstr(p+1, ",");  
           if(q!=NULL)  
           \{  
               strncpy(vanity, p+1, q-p-1);  
               printf("vanity=%s\\n",vanity);  
               strncpy(number, q+1, 64);  
               printf("number=%s\\n",number);  
          \}  
         else  
         \{  
              printf("Can't find , in %s\\n",p);  
         \}  
     \}  
     else  
     \{  
          printf("Can't find ; in phone list %s\\n",phone\_list);  
     \}  
    m = strtok(NULL, ";");  
 \}

运行结果为：  
quick\_dial\_code=11  
vanity=22  
number=33  
quick\_dial\_code=44  
vanity=55  
number=66  
quick\_dial\_code=77  
vanity=88  
number=99
