Reading number from a string

I have problem with string reading. From Hell13 World i need to get the number 13.

while (*znak){
   if (isdigit(*znak)){
    x=*znak - '0';
    printf("%d\n", x);
   }
    *dst++ = * znak;
    znak ++;
    }

with my solution, i get number 1 and number 3 separately.

You only get the first digit and then print it. After seeing a digit you must loop until you see no more digits.

if (isdigit(*znak)){
    while (*znak && isdigit(*znak))
        x= x*10 + *znak++ - '0';
    printf("%d\n", x);
}
