onlylonly

cout<<"Name :"<name<<<"ID :"<ID<<<"Phone Type:"<type<
   
name, id, type 从何处来？ id? list.id ?

还有，
void stack::push(string a, string b, string c)
{
     nodeStack* newnode;
     newnode->name = a;
     newnode->ID = b;
     newnode->type = c;
     newnode->next = Top;
     Top = newnode;
}

nodeStack* newnode; ？？ newnode 只是一个pointer， 她指向哪里？你要的应该是pop， 应该是
     nodeStack* newnode = new notestack; 吧？
