    concatenating 2 bytes of an array

    hello,

    I have an unsigned char array which is basically 17bytes long with a null terminator

    in the form 0 0 : 1 1 : 2 2 : 3 3 : 4 4 : 5 5 \0

    i can take the \0 off easily, but i would like to know how i can make a 6 byte array

    in the form 00 11 22 33 44 55


    this is what little code i have so far, however this only creates the 18 byte array which i dont want...
    Code:
    for(iterator = 0; iterator < num_hosts; iterator++){
    	while(i < 17){
    	//printf("%c",return_string[i+1]);
    	bdaddr[i] = return_string[iterator*25+i+1];
    	i++;
    	}
    	bdaddr[17+1] = 0x00;
    	printf("device: %s ",bdaddr);
    	i = 0;
    	//get_device_name(bdaddr, &remote_name);
    	//printf("name: %s\n\n",remote_name);
    }
    thanks for your help

    Use strtok() - check out this FAQ link that explains with code how to extract substrings delimited by tokens.
