getting the end of an web address in c? -

say pass argument www.bbc.co.uk/news/world-us-canada-11893886 need separate www.bbc.co.uk /news/world-us-canada-11893886 http get

i have tried using strtok , strcat come across weird splits @ runtime. can www.bbc.co.uk fine using strtok( host, "/");

i have tried using combination of strtok , strcat try , rest of string first "/" output this... request: da-11893886 tempstring: news/world! host: www.bbc.co.uk path: news/world!da-11893886

if @ output, strangest part cuts out middle section. in case, "-us-cana"

the section of code attached below

// testing purposes  printf("argv[1]: %s\n", argv[1] );   host = malloc(sizeof(argv[1]));  strcpy(host, argv[1]);  host = strtok(host, "/");   // request  request = malloc(sizeof(argv[1]) + sizeof(char)*6);   char *tok, *tempstring;  tempstring = malloc(sizeof(argv[1]));   tok = strtok( null, "\0");   while( tok ) {   strcpy(tempstring, tok);   printf("request: %s\n", request);   request = strcat(tempstring, request);   tok = strtok(null, "\0");  }   printf("host: %s\n", host);  printf("path: %s\n", request); 

thanks looking on this. direction or link site can figure out how appreciated.

 have modified code work way expecting 

 main(int argc, char *argv[])     {     char *request,*host,*req;      char *tok, *tempstring;     printf("argv[1]: %s\n", argv[1] );      host = malloc(strlen(argv[1]));      strcpy(host, argv[1]);      host = strtok(host, "/");        tempstring = malloc(strlen(argv[1]));       tok = strtok( null, "\0");      printf("sizeof(tok) %d\n",strlen(tok));       strncpy(tempstring, tok,strlen(tok));       while( tok ) {       tok = strtok(null, "\0");       if (tok != null) {       strncat(tempstring, tok,strlen(tok));       }else {        break;       }      }      request = tempstring;      printf("host: %s\n", host);      printf("path: %s\n", request);     }     ~ 

output

./tmp www.bbc.co.uk/news/world-us-canada-11893886/tmp.htmlargv[1]: www.bbc.co.uk/news/world-us-canada-11893886/tmp.html sizeof(tok) 38 host: www.bbc.co.uk path: news/world-us-canada-11893886/tmp.html bash-2.03$
