When the below code is run, I get garbage output. I have debugged it enough to figure out the error comes when I try to access hobbies[i]->hobby
. Any help would be appreciated. I have been trying to figure out what is going on for hours.
int Graph::addUserToHobby(std::string hobby, std::string id){
int key = ((int)hobby[0] + (int)hobby[1])%HASHMAP_SIZE;
int collisions = 0;
while(hobbies[key] != NULL && hobbies[key]->hobby.compare(hobby) != 0 ){
key++;
collisions++;
if(key >= HASHMAP_SIZE){
key = 0;
}
}
if(hobbies[key] == NULL){
hobbylist hob;
hob.hobby = hobby;
hob.list.push_back(findVertex(id));
hobbies[key] = &hob;
}
else{
hobbies[key]->list.push_back(findVertex(id));
}
return collisions;
}
void Graph::displayHobbies(){
for(int i=0; i<HASHMAP_SIZE; i++){
if(hobbies[i] != NULL){
cout << hobbies[i]->hobby << ": ";
for(unsigned int j=0; j<hobbies[i]->list.size()-1; j++){
cout << hobbies[i]->list[j]->name << ", ";
}
cout << hobbies[i]->list[hobbies[i]->list.size()-1]->name << endl;
}
}
}
