Thread: linked list help

Code:

struct BLOCK {
	vector <string> say;
	vector <string> resp;
	int index;
	BLOCK *next;
};

BLOCK *first;
	BLOCK *curr;

int cAIBrain::GetWords(char *strWork, char type){
	
	string temp;
	int numwords=0;
	BLOCK *insert = new BLOCK;

	//clear the >, so then the words are left
	for(int i=0;i<=strlen(strWork);i++){
		if(*strWork=='>')
			break;
		
		*strWork++;
	}

	*strWork++;	//clear the >
	while(*strWork!='/'){
		//next time change this with the delimiter chosen
		//by the user, for now it is a |
		if(*strWork=='|' || *strWork=='<'){
			*strWork++;

			if(type=='s')	 {	//if its a say block, add it to the say
				insert->say.push_back(temp);
			} else if(type=='r'){	//if its a resp block, add it to resp
				insert->resp.push_back(temp);
			}

			numwords+=1;
			temp="";
		} else {
			temp += *strWork;
		}

		*strWork++; //move to next character
	}

	AddNode(insert);
    
	return numwords;
}


void cAIBrain::AddNode(BLOCK *node) {
	if(first==NULL){
		first=node;
	} else {
		curr=first;

		while(curr!=NULL){ 
			curr=curr->next; //ERROR HERE!
		}
		curr=node;
		curr->next = NULL;
	}
}

I get an error in the "AddNode" function, that's the entire code. I think maybe my linked list implementation is off. I know its not optimized etc, I'm just trying to get it to work

i set first to NULL in the class initialization, but ahh i cant figure it out


thanks
