What am I doing wrong? This code gives a compile error:
'SortedList<T>: :insert' : illegal call of non-static member function. I've
tried several variations of this, but keep getting the same error.
template <typename T>
class SortedList
{
public:
void insert( T item); // Write this
};
//-------------------------------------------------
template <typename T>
void SortedList<T>:: insert( T item)
{
}
int main()
{
int i = 123;
SortedList<int> ::insert(i);
return 0;
} 7 32085

It looks like you are trying to call a member function from a class,
which cannot be done.
Try this insted:
int main() {
int i = 123;
SortedList<int> slist;
slist.insert(i) ;
}

The second line of main tries to call a class method, insert(), without
a class instance.

On the above line, you are calling a member function of SortedList<int> .
Since there is no object involved on that line, you can use that syntax only
with static member functions.
Since it is natural to 'insert' into a SortedList object, I don't think you
want that function to be static.
return 0; }
It looks like you are trying to call a member function from a class, which cannot be done.
Try this insted:
int main() { int i = 123; SortedList<int> slist; slist.insert(i) ;
On the line above, John Ratliff is showing you how to call a non-static
member function with an object. There, slist is an jobject of type
SortedList<int> , and the member function thas is being called is 'insert'.
}

Dooooohhhh!!!! I forgot to instantiate SortedList! Ack, I can't believe I
didn't see that - and John even showed how to do it.... :-P

Yes, I stupidly missed that, even though it was quite obvious. My apologies
for being so dense lol, and thanks as usual to all of the quick help I get
here. Next time I'll read the FAQ and try to come up with a tougher question

Binding a temporary to a non-const reference is illegal. Everybody
