recursion problem

[paper hound]

int caps(char *str) {
   if(str != NULL){
      if(isupper(*str)){
         return 1 + caps(str + 1);
      }
      else{
         caps(str+1);
      }
   }
   else{
      return 0;
   }
}

working on a recursion problem for homework and this is what I have so far but is giving a core dump, some help would be appreciated

wait i believe ive done it with ```c
if(*str != NULL){

odd that it gives me a warning but works

str + 1 will never point to null

strings are null terminated though, which is essentially what *str != NULL checks
