how to cut a string in C -

i have document telephone number , andresses. try copy numbers in 1 part of struct , adress another. @ moment able data of document can't put in struct please me

c code

#define _crt_secure_no_warnings #include <stdio.h> #include <string.h>  struct telefon{     char nummer[16];     char adresse[128]; };  typedef struct telefon telefon;  void main() {     telefon tel;     char buffer[256];     file *fp;     int = 0;     int countsemi = 0;      fp = fopen("telefondatei.txt", "r");      if(fp == null)      {         printf("datei konnte nicht geoeffnet werden.\n");     }     else{          while(fgets(buffer,1000,fp) != 0){             //printf("%s\n",buffer);             while(buffer != 0){                 i++;                 if(buffer[i] == ';'){                     countsemi++;                 }                 while(countsemi <= 7){                     strcpy(tel.adresse,buffer);                     printf("%s\n %d \n",tel.adresse,countsemi);                 }             }         }     } } 

example data in .txt document

"firma";"";"auto gmbh";"gasse 3";"5000";"mon";"";"0456";"45652" "firma";"";"adac";"";"50000";"mon";"";"2156";"545218"

you need use strtok additionally. see example. however, please note example assumes data written in fixed format (and not work if data comes in other format - might want modify needs, illustration):

assumed data format each line:

address;telephonenumber;

#include <string.h> .. char * value; while(fgets(buffer,256,fp) != 0) {    value = strtok(buffer, ";"); // address    strcpy(tel.adresse, value);     value = strtok(null, ";"); // number    strcpy(tel.nummer, value);  } 

also this:

while(buffer != 0) 

in code doesn't make sense. hardly buffer 0. array , value of buffer memory address array starts. can't assign buffer.
